Aligning with Invasive Trees as Herbal Medicine

This is part of a series of writings exploring plant communities and herbal practice in the Anthropocene….more to come.

Walking the urban sidewalks, riparian woodlands, and other forested areas around your home you may have noticed that the effects of globalization are not limited to fashion styles, international trade agreements, and other aspects of human culture. Plant communities are becoming globalized, too. That is to say, many ecosystems now include a russian-olive-branchmixture of native and non-native species that collectively create a new concept of what wild lands are today. This emerging new feature of landscapes is a defining characteristic of plant communities in the Anthropocene, the proposed current era in which humans are the primary influence on Earth’s systems. While we can agree that this change is undoubtedly taking place, what precisely is happening within these plant communities is not always clear. Arguments continue to be made that non-native plants are both harmful and beneficial to native plant communities. Regardless of how we feel about that, invasive plants bring something valuable to the medicine cabinet. As highly adaptable and opportunistic newcomers, they can sometimes play a remediation role in landscapes with moderate levels of disturbance. With this characteristic, invasive plants may be uniquely qualified to defend us against rapidly evolving pathogens, like drug-resistant flu strains and MRSA, if we allow them to colonize and infiltrate areas of the body struggling with dis-ease. Let’s take a quick look at why our ecological understanding of invasive plants remains unsettled and then see what roles five common non-native tree species can play in their ecosystems and in our apothecaries.

For decades, invasive non-native plants such as the infamous Salt Cedar/Tamarisk (Tamarix sp., shown below in flower) and many others have been vilified, poisoned, and scapegoated as the destroyers of ecosystems and the annihilators of biodiversity. In recent years a new perspective has emerged that these plants are, in fact, the saviors of ecosystems that have been severely altered by humans, reinvigorating the health of these systems and increasing biodiversity. How could we change our minds so dramatically and which viewpoint more accurately represents the role of these non-native plants? It would be nice if there was a simple answer but there is not. Every ecosystem and each one of these plants is unique. Furthermore, one species can play different roles in different situations, as invasive plants tend to proliferate in accordance with the degree of ecosystem alteration. We must also consider that ecosystems are continually dynamic. The kinds of changes that are taking place today are new patterns that are salt-cedar-flowersstill unfolding.  They are without historical precedent, which makes it difficult to accurately predict where these changes are taking any given plant community in the long term. Many plant communities of the Anthropocene will experience dramatic changes as new climate conditions accelerate and native and non-native plants co-mingle. Some experts see evidence for increased regional-scale biodiversity (while global diversity declines) as newcomers outnumber extinctions in the plant world and ecosystem fragmentation creates opportunities for new plant taxa to evolve but others warn of the likelihood that invasive plants will continue to expand their range at the expense of natives in the coming decades and centuries. Tamarisk, as one of the most successful and one of the most targeted non-native plants, exemplifies the ongoing debate about the role of invasive plants in regional biodiversity. Some of the accusations, such as the idea that it desiccates floodplains through high levels of evapotranspiration, have been largely debunked. Other assertions including its influence on vegetative biodiversity and impact on wildlife habitat are still debated with evidence pointing in different directions (more on this below).

I know it can be difficult to see the changes taking place in the wilds around us, but these plants are here to stay. They are a part of our local plant communities and we can align with the way nature unfolds around us by integrating them into our ecological understandings and into our herbal practice. In looking more deeply at the following non-native invasive trees, we can begin to understand their roles in our wild lands, how we can incorporate them into our medicines, and how our thoughts and opinions about them are evolving.

Russian Olive (Elaeagnus angustifolia):

Ecological: Arriving from Asia and southern Europe in the 1800s, Russian Olive (also shown flowering in top photo) has come to fill an ecologicalrussian-olive-tree niche in the altered environments downstream from dams. It fixes nitrogen in the soil, provides forage for wildlife, and nectar for pollinators. Once established this tree has a tendency to become dominant or co-dominant in the landscape, sometimes forming mono-typic stands. Although the changes in water flow caused by dams are a primary driver in the changing plant communities and the successful establishment of Russian Olive, Russian Olive accelerates human-caused changes by stabilizing soil surfaces and shading out seedlings of native pioneer species such as Cottonwoods that rely on flood disturbance areas for germination and open sunny conditions to grow. It may be considered a thorny protector of damaged ecosystems in some cases, but it may also be a facilitator of change contributing to the reduction in biodiversity by inhibiting the reproduction of keystone native plants in stressed riparian areas.

Medicinal: Leaves and stems can be harvested for antimicrobial/antibacterial/antifungal medicinal preparations for wound care or systemic infections. Russian Olive is also used when an anti-inflammatory or muscle-relaxing analgesic is needed. Extracts of this plant have been shown in clinical trials to be as effective as NSAIDS for relief of pain and inflammation but with added gastro-protective properties. Research also suggests that it may optimize blood pressure and have anti-tumor properties.

 

Siberian Elm (Ulmus pumila):

Ecological: Another Asian tree, Siberian Elm is the first tree to leaf-out all over my fair city each spring. The burst of green is followed by the raining-down of confetti as its seeds fill siberian-elm-leavesthe air and germinate wherever they land, in between concrete cracks or the earthly surfaces of the surrounding natural areas. This tree is known to spread quickly in disturbed areas and will tolerate difficult growing conditions where few others can succeed. Siberian Elm binds heavy metals in soil, providing remediation in polluted urbanized areas and provides early spring nectar for pollinators. Along with Russian Olive and Tamarisk, Siberian Elm is one of the trees expected to redefine the Cottonwood Bosque along the Rio Grande in the coming decades if water management practices remain unaltered.

Medicinal: This invasive tree is a very useful and abundant medicine and wild edible. The inner bark can be collected and powdered as a substitute for the threatened and popular medicine of Slippery Elm. It is anti-parasitic, antifungal, antilithic, expectorant, and demulcent. Next time you find Siberian Elm growing through your backyard fence or coming up along a roadway, cut off a small branch, peel off the bark, and feel its soft slippery mucilage inside. Recent research also suggests its potential usefulness in cervical, melanoma, breast, and lymphoma cancer treatments. Gathered in the early spring while still green, the seeds are a nutritious edible and are tasty served raw on top of salads, in sandwiches, and as an edible garnish.

 

White Mulberry (Morus alba):

mulberrries-eatingEcological: Probably the least invasive of the trees discussed here (at least in my area), Mulberry is a common yard tree and has also made a home for itself in the riparian corridor. Originating in China, it came to the eastern United States in the 1600s as part of a British effort to establish a silk industry. Although it can form dense thickets in some places, White Mulberry typically does not grow in clusters. Little information has been published regarding its impacts on native plant communities.

Medicinal: Mulberry has a long history of use in Chinese medicine with different parts of the tree being used for different areas in the body. The leaves are antimicrobial, detoxifying, cooling, and moistening to dryness in the upper body, particularly the head, throat, and lungs. The twigs are used to increase circulation in the joints and extremities. The bark is anti-inflammatory and increases the movement of fluids in the lower body and the fruit is a nourishing antioxidant tonic for heart health. Also the fruit is delicious to eat right off the tree.

 

Tree of Heaven (Ailanthus altissima):

Ecological: Originally from China and Taiwan, this tree is considered by some to be an unstoppable menace sending new shoots up wherever possible. It will grow in a variety of tree-of-heaven-seedingchallenging environments including urban areas that are heavily concretized or contaminated and degraded natural areas such as disconnected floodplains in riparian corridors. Growing in such conditions, it can act as a remediator of damaged land and polluted air but its propensity for sending up new shoots could prove to be a problem in ecosystems where there are not sufficient factors to limit its growth.

Medicinal: Tree of Heaven can also play a remediation role in the digestive and respiratory systems. It is an antimicrobial, astringent, febrifuge, anthelmintic, antispasmodic, antiseptic, expectorant, clearing heat and dampness in the body. The stems, leaves, and especially the root bark are useful in treatments for diarrhea and digestive ailments caused by microbes and parasites including Giardia. In the respiratory system it reduces inflammation and cleans the airways of mucus and other irritants, facilitating recovery from a variety of ailments. Additionally, Tree of Heaven is soothing to the nervous system and helpful for reducing muscular contractions, shakes, and tremors.

Salt Cedar/Tamarisk (Tamarix spp.):

Ecological: The poster child for vilified non-native invasive plants since the early 1900s, Tamarisk is the most successful non-native tree in the western United States and has become the third most common woody plant in that region’s riparian corridors. Originating from the Mediterranean and Asia, it has come to symbolize the water struggles of the Southwest by covering well over 600,000 hectares of severely degraded riparian salt-cedar-bighabitat in the Southwest. Numerous bird species use it for shelter including the endangered Western Willow Flycatcher but overall Tamarisk forests support fewer species and fewer individuals than native forests. It is an opportunistic reproducer that is tolerant of drought, heat, fires, and saline soils. Similar to Russian Olive, it stabilizes surface soils inhibiting the germination of native riparian trees and shades out native tree seedlings. It can grow in vast mono-typic stands forming dense thickets, changing soil composition, and greatly reducing the beneficial mycorrhizal community that facilitates native plant growth. Like Russian Olive, Tamarisk finds a habitat niche in degraded riparian ecosystems with altered flow regimes and contributes to the process of change initiated by human interference. This tree may be considered a willing colonizer of damaged ecosystems where natives are in decline but it can also play a role in inhibiting the growth of native plants and further reducing biodiversity.

Medicinal: The bark and galls are harvested and used for topical application or small internal doses. It is an effective antimicrobial, antioxidant, diaphoretic, diuretic, astringent, and detoxifier that is used to make first aid wound washes or mouthwash. Internally it can be included in formulas for detoxification, microbial diarrhea, and other infections.

For the Love of Weeds ~ Wild Lettuce and Company

A weed by almost any account…

Horehound the weed-2What do we mean when we call a plant a ‘weed’? Usually that indicates a plant that is growing where we don’t want it to be, a plant that spreads prolifically, or a plant that competes with others we regard to be of higher value. This Horehound (Marrubium vulgare, see photo) certainly is growing with great abundance, having spread throughout my garden on its own accord. It also grows out of the cracks in the concrete walkway leading to the shed in the hinter-lands of my yard. I’ll admit that it also crowds out some plants with more demure personalities. But what about the connotation of the word ‘weed’? Usually it is negative and that is where some of us beg to differ. Weeds, as a group, are my favorite plants. They offer nutrition, medicine, food and habitat for pollinators and other wildlife, and they hold down the fragile desert topsoil after disturbance. I love their tenacity, persistence, and their willingness to stand by our side, regardless of how destructive we may be to the natural cycles of things. I feel that they accept us as we are and offer so much, so freely. Horehound for example, is a pure beauty. Not in the traditional sense, of course. Its got tiny, barely noticeable flowers and produces annoying burrs that get stuck in everyone’s clothes and hair. But that wild form and that penetrating aroma! One whiff and I am taken back to times and places of healing and recovery. Bitterness, expectoration, and the bees simply love her.

 

Weeds are inevitable in our lives so why not make the most of it? Just like our digestive Arugula wild Bosque flower croppedsystems, which are colonized by microbes, so too will our gardens and urban areas become prime habitat for opportunistic plants.  As with our own bodies, we want those to be helpful or useful organisms and lucky for us most common weeds are actually very valuable plants.   Many of those pesky weedy plants growing in your yard and garden make tasty and nutritious foods and they make great medicine, too.  As foods, many weedy greens, flowers, and seeds add an array of wild-spirited phyto-nutrients to your diet.  Wild Lettuce (Lactuca serriola) and Wild Spinach (Chenopodium) are two of the most abundant wild vegetables that make up my spring and summer diet.  Harvesting invasive mustards such as London Rocket (Sisymbrium irio) and Wild Arugula flowers (see photo) are another way to add easy wild beauty to your meals while incorporating a little punch of mustard flavor.  Likewise, Siberian Elm (Ulmus pumila, see photo) and Common Mallow (Malva neglecta) provide a seemingly endless supply of tasty green seeds plentiful for the picking during early spring and mid-summer. I particularly enjoy using weeds in my food and medicine because of their wonderfully tenacious and persistent nature and their ability to adapt to wide-rangingSiberian Elm seeds 3 conditions, thriving in even the most inhospitable of environments. Weeds are unique and intriguing in their paradoxical way of being in the natural world. They are stubborn in their resilience, yet yielding in their willingness to be harvested and included in any herbal arts. I like imbuing my meals and formulas with this sort of life force and plant personality because we all need a little more durability and adaptability at times. If there were ever herbs to help us meet success against the odds, we will find that medicine in ordinary weeds.

 

 

Many of our most common medicinal weeds are so adaptable and successful that they are seen ubiquitously across much of the country. Dandelion (Taraxacum officinale), Plantain (Plantago major), and Clovers (Trifolium spp.) are all plants that are widely familiar and help to create shared experiences and herbal practices for people across the continent. However, what plants are considered to be weeds varies depending on where you Geranium filaree patch 2live. For example, Burdock (Arctium minus), St. John’s Wort (Hypericum perforatum), Mullein (Verbascum thapsus), Self Heal (Prunella vulgaris), Nettles (Urtica dioica), and Dock (Rumex crispus) are all useful herbs that are considered to be weeds in some regions. Local medicinal weeds most commonly seen in my area include Dandelion, Sunflower (Helianthus annuus), Plantain, Redstem Filaree (Erodium cicutarium, see photo), Shepherd’s Purse (Capsella bursa-pastoris), Sweet Clover (Melilotus spp.), Common Mallow (Malva neglecta, see photo), Siberian Elm, and Wild Lettuce among others. Collecting a basket full of these weedy herbs will provide you a wide variety of medicinal effects including nutritives, diuretics, choleretics, astringents, demulcents, emollients, styptics, lymph and blood movers, stomachics, immune modulators, anti-spasmodics, and more. These persistent plants can be made into tinctures, salves, creams, sprays, tea, food, liniment, poultices, soaks, and anything else you can dream up.  Working withMalva neglecta flower2 weeds, we integrate ourselves more deeply with our immediate surroundings, we create a more sustainable and cost-effective practice, and we can produce formulas for health and well-being while alleviating the pressure on less common medicinal plants.  In a world of changing plant communities and growing human populations, I am always grateful for those plants that are willing to grow alongside us in the perpetual and dramatic landscape alterations that we make.

 

Wild Lettuce:

Wild Lettuce (Lactuca serriola) is one of the local weeds that I most commonly call upon in my herbal practice. I love its scruffy yet elegant form, its an abundant and nutritious spring green, and its medicine is as good as any of the other herbs that I find growing around me.  It was one of the first herbs that transformed my thinking about weeds years ago.  While pregnant with one of my children, I came down with a vicious and unrelenting cough that rocked my third trimester world.  My herbal mentor at the time gave me a formula that effectively relieved the coughing when nothing else worked.  It was a weedy remedy that included Wild Lettuce.  That experience changed my life as I began to realize the power that resided iWild Lettuce rosette.JPGn some of the overlooked and under appreciated living beings all around me everyday.

Wild Lettuce is a prolific reproducer that thrives in the most hostile of environments. I often see this plant growing happily out of cracks in the sidewalk, in vacant lots, or along the busiest of highways. In its early stages (see upper photo) Wild Lettuce can be confused with Dandelion or other weedy green rosettes, so look for the spiny hairs on the midrib under the leaves and on the mature stem (see lower photo). In the spring (around here that’s March and April), Wild Lettuce leaves are still young, supple, and good tasting.  Gather them for cooking at this time befoWIld Lettuce leaves and pricklesre the central main stem begins to form.  Use it as you would any other leafy green in your daily culinary arts (see bottom photo).  Once the central stalk grows, it becomes rather bitter tasting and much more fibrous in texture.  Now it is moving into its medicinal phase.  This plant’s mild pain relieving action and its anti-spasmodic properties make it a great addition to any formula for coughing, cramping, or other twitchy uncomfortable situations. I also add the tincture to sleep formulas, especially for those who toss and turn at night. In order to incorporate the milky white secretions from the woodier parts of the plant, tincture Wild Lettuce fresh and include the main stem. This plant can grow in dense stands where ample water resources exist (such as your garden) so make sure to look for mildew, which can grow on the leaves and appears as a white powdery film.

Ready to get started?  Try making your own Wild Lettuce Polenta Casserole.  This is a simple and versatile recipe that can be prepared with endless variations according to the foods that are in season around you.  Its gluten free and you can make it vegan by replacing the butter with coconut oil and leaving out the cheese.  Here’s what you’ll need:

Polenta Layer:

  • 4 cups of water
  • 1 1/2 cups cornmeal
  • 2 TBSP of butter or cooking oil of choice
  • a sprinkling of dried crushed Bee Balm (Monarda) or Oregano
  • a sprinkling of Cayenne to your taste
  • 1/2 cup pecorino cheese (optional)
  • a pinch of salt

Vegetable Layer (Use vegetables of your choice, but here’s what I like.):

  •  1 to 2 chopped onions
  • 3 cups of chopped mushrooms
  • 2 cups of chopped Wild Lettuce leaves
  • 2 or 3 chopped garlic cloves
  • add more herbs of your choice including more Monarda, fresh Basil, or Rosemary
  • enough oil to saute the vegetables

Cheese Layers:

  • 2 cups of grated cheese  (I like to use sharp cheddar, but it comes out nicely with others, too, including dill havarti.)

Toppings:

  • Add more color with sliced tomatoes or thinly sliced red bell peppers.
  • Add protein by sprinkling with ground nuts and seeds such as almonds or hemp seeds.
Wild Lettuce Polenta Casserole

Making Wild Lettuce Polenta Casserole

Directions:

  • Cook your polenta and layer it on the bottom of your casserole pan.  To cook the polenta, bring the water to a boil and add the remaining polenta layer ingredients, whisking constantly.  Cook this mixture on a low simmer, whisking frequently, for about 15 to 20 minutes.  It should be smooth, not gritty in texture, and the water should be fully absorbed. When it is finished, put it in the bottom of an oiled casserole pan.
  • In another pot, saute the onions, garlic, and herbs for the vegetable layer.  Add the Wild Lettuce leaves and a small amount of water.  Cover and cook for several minutes.  Then add the mushrooms and continuance cooking, covered, until the vegetable are to your liking.
  • Back to the casserole pan with the polenta in it. Layer half of the cheese on top of the polenta and then add the vegetable layer on top of that.  Cover it with the rest of the cheese and your other toppings.
  • Cover the casserole with foil and bake in an oven preheated to 350 degrees for about 10 minutes or until the cheese is melted.

Herbal Shorts from the Rio Grande Bosque

Yerba Mansa Path 3If you haven’t figured out that I love the Rio Grande Bosque by now, you are falling behind. I’ve already written about lovely Yerba Mansa and her companion Cottonwood, but what about all those other plants hiding away in the understory? The understory of the Middle Rio Grande Bosque can be quite varied. Some places far enough downstream from Cochiti Dam are more wild and jungle-like with lower riverbanks and side channels of water that nourish the health of the ecosystem. Meanwhile in other places, including much of the Rio Grande Valley State Park within the city limits of Albuquerque, the understory is often open with few plants to speak of or it is covered in weedy non-natives such as the dreaded prickly Kochia. Furthermore, the Bosque is a mosaic of differing habitat types including native Cottonwood stands, invasive Salt Cedar stands, open areas, riverbanks and sandbars, and wetlands.  Exploring the healthier areas of this ecosystem brings unexpected experiences like feeling lost within a rare urban wilderness area or discovering hidden jewels within the dense off-trail vegetation. Here is a small selection of those treasured plants of our wild Bosque:

.

Blue Lettuce (MulgediumBlue Lettuce twin flowers pulchellum or Lactuca tatarica var. pulchella): Blue Lettuce is a native sister of the more common non-native weed Lactuca serriola, or Wild Lettuce, and is present across much of North America. Both share many common attributes including bleeding a milky sap with medicinal properties. This sap is captured in fresh herb tinctures made from all parts of the plant (especially leaves, and stems) and used as part of formulas for promoting restful sleep, calming bodily spasms, relaxing tension and anxiety, coughing, and even acts as a mild pain reliever. Additionally Blue Lettuce is a tasty wild green when collected early in the spring.

.

Pale Wolfberry (Lycium pallidum): This powerful member of the Solanacaea family is a Wolfberry Pale flowersmedicinal shrub related to the more famous Goji berry.  Wolfberry, however, should be used in moderation and works well in formulas where the dosage will be smaller.   Too much of this plant can create imbalance, dryness, and heat—exactly what we don’t need here in the Southwest. It combines well with other herbs that get at the root causes of illness while Wolfberry eases symptoms. Collect the leaves for tincturing or keep some stored dry to reconstitute for topical applications. The latter comes in handy for the pain and swelling that often comes with summertime’s bites, stings, and rashes. In that case, you can mix the powdered herb with some clay and water or just water to make a nice soothing paste. Wolfberry also works in the respiratory system by opening chest congestion and drying the wetness of allergies. It is also an effective anti-spasmodic in the digestive system.

 

Licorice flower BosqueAmerican Licorice (Glycyrrhiza lepidota): Our native Licorice is a frequent find when walking through the Bosque or along Albuquerque’s acequia system (irrigation ditches that carry water throughout the valley). Often this plant grows in compacted soils, which makes digging the roots a difficult chore. Unlike other species of Licorice, ours contains little glycyrrhizin and lacks the super-sweet flavor that typifies this plant. This may be a benefit for those who do not care for the flavor of purchased varieties of Licorice or for those who have contraindications to using this plant. (Usual contraindications include high blood pressure, edema, and diabetes.) Licorice has been used for centuries (or longer) for the treatment of a long list of health conditions including all kinds of inflammations and viral infections, especially coughs and sore throats.  Like other members of the Legume family, Licorice has an important ecological role to play though its symbiotic relationship with soil bacteria and by fixing nitrogen in the soil.

.

Canadian Fleabane (Conyza canadensis): I did not intend to discuss weed species in this Canadian Fleabane leavespost, but I could not resist including this abundant and useful native that is so widespread in the Bosque as well as other areas across the entire continent. The upper leaves of this plant make useful digestive remedies, especially for chronic inflammatory issues, leaky gut, diarrhea, and indigestion. This plant has a unique spicy flavor and can be used to create interesting culinary creations in your kitchen. One of my favorite ways to prepare it is to infuse the leaves in oil or vinegar and use it for medicinal foods, salad dressings, and marinades.

Honeysuckle Bosque 3

.

Japanese Honeysuckle (Lonicera japonica): It seems that every environment in this modern global era must be defined, in part, by the invasive non-natives. That’s why I am including one of them here for the Bosque and believe me there are many to choose from. Besides we can do the ecosystem a favor by harvesting the invaders’ flowers. Honeysuckle flowers are cooling for hot inflamed conditions and provide antibacterial and antiviral power. Prepare as tincture, tea, glycerite, or infused honey.
