Usnea: Nature’s Antibiotic

by
Usnea—Old Man’s Beard—is one of those wild medicines that seasoned Michigan foragers and hard core survivalists learn to spot long before they ever need it. Out in the backwoods around Manistee and the Great Lakes, you’ll see it swaying from conifers and old hardwoods like ghost green sinew, light as air but tough enough to stretch without snapping. When you’re miles from a trailhead and the nearest first aid kit is whatever you can scavenge from your pack, this stringy lichen becomes more than a curiosity. It’s a field tested ally. For generations, woodsmen, trappers, and modern bushcrafters have turned to Usnea as a reliable topical antiseptic and emergency wound dressing—one of the few things in the forest you can grab straight off a branch and put to work. Many call it nature’s antibiotic, and while that’s a folk nickname rather than a clinical claim, its long history of use speaks for itself.
What it is and where to find it
Usnea (Old Man’s Beard) is a fruticose lichen that grows as long, stringy, beard like tufts on branches and rocks. It often hangs from twigs in shady, humid stands—look for it on conifers and older hardwoods near lakes and wetlands in northern Michigan. Usnea is also an indicator of clean air and is common in less polluted forest pockets.
How to identify it by its stringyness
• Appearance: pale green to gray green strands, sometimes several inches to feet long.
• Pull test (definitive): a strand pulled apart reveals a white, elastic inner cord (the central axis) and the outer cortex flakes into pale green particles that feel slightly elastic. This “stringy” elasticity distinguishes Usnea from look alikes.
Why foragers and survivalists value it
• Primary traditional actions: antimicrobial, antifungal, antiviral, anti inflammatory, wound healing, analgesic, antioxidant. Usnic acid and polyphenols are the compounds most often credited with these effects; lab studies show activity against Staphylococcus and other gram positive bacteria.
• Practical survival uses: lightweight wound dressing, emergency antiseptic poultice, tinder in wet conditions (when dry), and a field antiseptic for minor cuts. Every part of the dried thallus has been used in folk medicine.
Simple preparations (folk recipes)
• Tea (infusion): 1 cup water : 1 teaspoon dried usnea. Bring to a boil, reduce to a simmer, cover 30 minutes, cool and strain. Traditional dose: up to 1 cup, 3× per day in folk practice (not a medical recommendation).
• Tincture: alcohol extraction of dried usnea for throat or topical use.
• Topical: powdered dried usnea in salves, creams, or as a poultice for minor wounds and infections.
Safety, limits, and evidence
• Major safety warning: usnic acid has been associated with hepatotoxicity, including severe liver injury and rare deaths after oral supplement use; regulatory and toxicology reviews document this risk. Do not take internal usnea preparations without consulting a clinician.
Foraging ethics and quick tips for Michigan
• Harvest sustainably: take small amounts from multiple trees, avoid rare species, and never strip entire clumps. Usnea regenerates slowly.
• Collect from clean air sites: avoid lichens near roads or industrial areas. Store dried usnea in a breathable container and label with location/date.
Bottom line: Usnea is a true field apothecary for Michigan foragers and survivalists—an easy to identify, stringy lichen with powerful topical antimicrobial uses—but internal use carries documented liver risks, so treat it as a traditional emergency tool rather than a substitute for professional medical care.

Mullein

by
 

Mullein (Verbascum thapsus) is one of the most valuable wild plants a forager or plant‑medicine enthusiast can know. It thrives where other plants struggle—poor fields, sandy soil, waste areas, and sun‑baked ground. You’ll often find it along railroad tracks, abandoned lots, and dry open spaces where its unmistakable form stands out.

In its first year, mullein grows as a low rosette of large, gray‑green, fuzzy leaves. These soft, felted leaves are one of its most recognizable features. In the second year, it sends up a tall flowering stalk that can reach six feet or more, topped with bright yellow blossoms from July through September.

Mullein has a long history in traditional herbalism, especially for respiratory health. The leaves and flowers make a soothing tea that supports the lungs, acts as an expectorant, and calms irritated mucus membranes. It has been used for chest colds, asthma, bronchitis, and persistent coughs. The yellow flowers infused in honey create a highly effective natural cough syrup. The same flowers soaked in warm olive oil have been used as a classic remedy for earaches.

Modern herbalists value mullein for its antiviral, antibacterial, antiseptic, and anti‑tumor properties. Its antimicrobial nature is one reason it performs so well as a wound dressing. The leaves can be used as makeshift bandages or gauze, and their strong anti‑inflammatory action makes them useful for wrapping sprains or twisted ankles. Some foragers even place a leaf in the sole of a boot for a mild energizing effect during long treks.

Mullein also offers a double‑duty poultice system. First‑year leaves can be mashed into a poultice and applied directly to wounds. Larger second‑year leaves can then be wrapped around the poultice to hold it in place. The plant’s tall dried stalks have their own uses: they can be turned into hand‑drill spindles for firecraft, and the leaves can be charred to make excellent char cloth. In winter, the dead stalks make mullein easy to locate even under snow.

The plant’s root has been used traditionally for certain types of lung support and musculoskeletal issues. Some herbalists dig it in late fall or winter when the plant’s energy has returned to the root.

Mullein’s yellow flowers and dried leaves have also been used in steam inhalations, and historically, some cultures smoked small amounts of dried mullein leaf to soothe the lungs. The plant contains compounds that help open the airways and calm irritation.

A few cautions are worth noting. The leaves are covered in fine hairs that can be itchy or irritating to some people, especially when handled fresh. These hairs are also why mullein leaves should not be used as a water filter, despite occasional claims—those hairs can irritate the throat if ingested. When making teas or infusions, strain thoroughly through a fine cloth to remove the hairs.

Despite these cautions, mullein remains one of the most versatile and generous plants in the wild landscape. From medicine to firecraft to field‑expedient first aid, it is a cornerstone species for anyone serious about foraging, herbalism, or survival skills.

Turkey Tail Mushroom: The Forest’s Toughest Healer

by
The turkey tail mushroom (Trametes versicolor) is a tough, wood-loving fungus that thrives on dead hardwood in forests across the globe. Its name comes from its layered, fan-like shape and earthy bands of brown, gray, and rust, resembling the tail feathers of a wild turkey. It’s not flashy, but it is definitely unmistakable.
This mushroom isn’t just a survivor—it’s a healer. Used for centuries in traditional Chinese medicine, turkey tail is packed with immune-modulating compounds like PSK (polysaccharide-K) and PSP (polysaccharide peptide). These have been studied for their ability to support cancer therapies, improve gut health, and strengthen immune response. In Japan, PSK is even approved as a cancer adjunct therapy.
At Arcturus Primitive Skills Institute, it is one of the mushrooms I point out and cover when we go on a foraging mission. Sometimes I will even make a tea out of it.
How to prepare turkey tail tea:
1. Identify and Harvest Carefully • Look for Trametes versicolor growing on dead hardwood. • Confirm identification: real turkey tail has white pores underneath, unlike the smooth underside of false turkey tail (Stereum ostrea). • Harvest sustainably—cut rather than rip, and leave some behind to continue decomposing the wood.
2. Clean the Mushrooms • Brush off dirt and debris. • Rinse briefly in cold water, then pat dry. • Avoid soaking, as this can degrade the mushroom’s texture and potency.
3. Dry for Storage (Optional) • If not using immediately, dry the mushrooms in a dehydrator or by air-drying in a well-ventilated space. • Store in a sealed jar away from light and moisture.
4. Brew the Tea • Use about 2–4 grams of dried turkey tail (or 4–8 grams fresh) per cup of water. • Add mushrooms to a pot with water. • Simmer gently for at least 1 hour, up to 2 hours for stronger extraction. • Optional: add ginger, cinnamon, or lemon to improve flavor.
5. Strain and Serve • Strain out the mushroom pieces using a fine mesh or cheesecloth. • Drink warm or refrigerate for later use. • The taste is earthy and slightly bitter; some prefer mixing it with herbal teas or honey.
6. Dosage and Frequency • Many people drink 1–2 cups daily for immune support. • Effects are cumulative, so consistency matters more than quantity.
Turkey tail is a symbol of endurance. It grows year-round, even in harsh conditions, quietly recycling dead wood into fertile soil. It’s one of the first mushrooms foragers learn to identify—not because it’s edible, but because it’s safe, common, and medicinally potent.
Turkey tail has the following medicinal applications:
• Immune System Modulation Rich in polysaccharides like PSK and PSP, turkey tail helps regulate immune responses. It’s used to support recovery during chemotherapy and radiation and may enhance the body’s ability to fight infections.
• Anti-Cancer Properties PSK is approved in Japan as an adjunct cancer therapy. Studies show it may help slow tumor growth and improve survival rates when used alongside conventional treatments.
• Gut Health and Microbiome Support Turkey tail contains prebiotic fibers that nourish beneficial gut bacteria. This can improve digestion, reduce inflammation, and support overall metabolic health.
• Anti-Inflammatory Effects The mushroom’s bioactive compounds may help reduce systemic inflammation, which is linked to chronic diseases like arthritis, heart disease, and autoimmune conditions.
• Blood Sugar Regulation Some studies suggest turkey tail may help lower blood glucose levels in people with type 2 diabetes, potentially aiding in metabolic control.
• Cognitive and Nervous System Support Early research indicates potential neuroprotective effects, including improved memory and brain function, possibly due to its antioxidant and anti-inflammatory properties.
• Liver Protection Turkey tail may help protect liver cells from damage caused by toxins or infections, though more research is needed to confirm this benefit.
• Antiviral and Antibacterial Activity Extracts from turkey tail have shown promise in fighting viruses and bacteria, making it a candidate for natural antimicrobial support.
These benefits are typically accessed through capsules, powders, or tinctures, as the mushroom itself is too tough to eat. While promising, it is important to consult a healthcare provider before using turkey tail therapeutically, especially alongside other treatments.

Wheeping Forsythia: Medicine of the Yellow Flower

by

Wheeping Forsythia

Weeping Forsythia (Forsythia suspensa) is a hallmark of spring, and one of the first bloomers to catch my eye each season. I typically spot this plant alongside Snowdrops early in the year. It has been valued in traditional medicine since ancient times for its numerous health benefits. The yellow blossoms can be eaten raw, though they are bitter. However, the flowers make a pleasantly flavored tea. Below are some of the plant’s medicinal uses:

• Anti-inflammatory properties: Weeping Forsythia contains compounds such as phillyrin and forsythoside, which help reduce inflammation throughout the body.

• Respiratory health: It can reduce inflammation in the air passages of the lungs (bronchiolitis).

• Antibacterial properties: The plant inhibits the growth of bacteria such as Staphylococcus aureus.

• Antiviral benefits: Prepare a tea using the flowers and consume it when dealing with colds, the flu, or other viral infections. Gargling the warm tea can also soothe a sore throat. Additionally, it boosts the immune system, aids in tonsillitis relief, and reduces fever.

• Allergy relief: In spring, I use this plant along with Purple Dead Nettle to alleviate allergies.

• Heart health: The plant contains oleanolic acid, which supports heart muscle function and helps regulate blood pressure.

• Pain relief: Weeping Forsythia’s analgesic properties are effective for relieving pain and headaches.

• Topical applications: Prepare a fomentation or wash with the plant for antiseptic use. The tea can be used to clean wounds, cuts, burns, rashes, and other skin problems.

• Support for internal organs: The plant is beneficial for liver health and can help regulate blood sugar levels.

Methods to Prepare Weeping Forsythia for Medicinal Uses:

  1. Tea: Use a tablespoon of fresh or dried yellow flowers and steep them in hot water for 10–15 minutes. This tea helps with fever, sore throat, and inflammation.
  2. Tincture: Fill a mason jar with dried fruits and leaves, then cover them with vodka or brandy. Seal the jar and let it sit for 4–6 weeks, flipping it upside down once a week. Afterward, strain and store the liquid. This tincture offers potent medicinal benefits, boosting your immune system and aiding in fighting infections.
  3. Infused oil: Place dried flowers in a jar and cover them with almond, olive, or coconut oil. Let the jar sit for 4–6 weeks, then strain and store the oil. This infused oil can be used for topical applications, including burns, wounds, and sunburns.
  4. Syrup: First, prepare a tea using the flowers as described above. Strain out the flowers and mix the tea with honey. Store the syrup in the refrigerator for up to one month. This syrup is effective for treating coughs, colds, the flu, other viruses and lung ailments.
