White Willow Bark (Salix alba)

Family: Salicaceae

Part Used: Bark

Flavor/Aroma: Astringent; Bitter

Energetics: Cooling; Drying

Overview:

In 1828, the active constituent salicin was isolated from Willow bark, paving the way for its modern application in drugs such as Aspirin and other pain-relieving therapeutics. Before this pharmaceutical adaptation, Willow was being utilized amongst Native American tribes, vikings, and in ancient civilizations in Asia for thousands of years. Willow botanical medicine has a great potential for a variety of systemic pain that should not be overlooked.

Willow trees can grow to a mighty 80 feet tall in ideal conditions. Its bark matures from a smooth, light-colored look to deeply cracked, darker pigmented expression. The leaves provide a full canopy and are serrated, slender, and elongated in appearance. Willow prefers to grow close to rivers and streams in disturbed, wetter soil types. They are also helpful in maintaining soil integrity and preventing erosion. Willow will express flowers in the spring to early summer months.2

Cultivation and Harvesting:

Willow species are native to Europe and were introduced to the United States as medicinal and ornamental botanicals. It is easily propagated using a piece of a branch by simply partially burying it in soil and allowing roots to generate. Willow bark is best harvested with care in the early fall, before the buds on the branches begin to fully express, but after the flowers have cycled. The easiest way to harvest is by cutting a few younger branches from the tree and stripping them for their bark, and propagating them as to regenerate this valuable medicinal herb.

Southern Oregon Cultivation:

Willow species are commonly found throughout the Rogue Valley and Southern Oregon regions. Although usually found near water sources, Willow makes a great addition to most home-garden spaces and provides an excellent source of shade when cared for properly. It is popularly used as a living fence in landscape design and can offer a unique aesthetic appeal.

History and Folklore:

American Native Uses: Due to the unique flexibility of Willow branches, they were commonly harvested for crafting uniquely weaved baskets, bed frames and other furniture, and for sweat lodges and ceremonial spaces. Willow was commonly brewed into tea to remedy systemic pain and the younger shoots were chewed-on for their analgesic effect. WIllow was used as a febrifuge by the Cherokee and Blackfoot, and as an analgesic by the Eskimo and Iroquois. Willow trees were the clan symbol of the Hopi, Kahabi, Navajo, Apache, and Pueblo tribes. 

WIllow became known as the “toothache tree” by many, and was used to treat a variety of aches and pains.5

European Medicinal Uses: Willow bark was commonly infused into teas to treat pain, chronic diarrhea, dysentery, to dispel worms, and to support debility of the digestive organs. It was also used in crafting and weaving techniques in certain cultures across the continent.1, 2    

Modern Applications:

White willow bark (from the Salix alba tree) has been used for centuries and is often recognized for its constituent, salicin, which is a chemical precursor to salicylic acid. This is the same class of compounds from which the synthetic drug aspirin was developed. Modern uses of white willow bark are primarily studied in the context of its traditional applications.

Key Points for Education on White Willow Bark:

• Mechanism of Action: White willow bark contains a compound called salicin. When ingested, the body metabolizes salicin into salicylic acid. Salicylic acid is believed to be responsible for the plant's effects. The bark also contains other compounds, such as polyphenols and flavonoids, which may work synergistically with salicin.

• Forms of Use: White willow bark is available in various forms, including capsules, tinctures, powders, and teas. The concentration of salicin can vary significantly between different products and preparations.

• Current Research and Studies:

  • Musculoskeletal Discomfort: Some studies have investigated the use of white willow bark for occasional discomfort in the lower back and joints. A few clinical trials suggest that extracts may offer some benefit for short-term improvements in these areas, although results can be mixed. Higher doses of salicin have been noted to be more effective than lower doses in some studies.

  • Other Traditional Uses: Historically, white willow bark was also used to address fever and headaches. While some people continue to use it for these purposes, there is limited scientific evidence from clinical trials to support these uses.

Uses and Preparations

Dried Herb Tea Preparation: 

Place 1 Tablespoon and broken bark into a pot of cold water and boil, allowing it to decoct for at least 5 minutes. Drink 3 to 4 times daily.

Using a reusable tea bag or tea ball, immerse the loose dried herbs into boiling water and allow to steep for 5-10 minutes, preferably covered, in order to release the maximum amount of herbal goodness. Some herbal tea can carry a strong flavor. We recommend organic honey as a sweetener which preserves the beneficial herbal compounds. 

Tincture: 

4-6 mL up to 3 times daily.

Some herbal tinctures can have a strong flavor on their own. Adding your tincture to a glass of 6-8oz of water is one easy way to help, should you wish to dilute the flavor.

Precautions:

We recommend consulting with your practitioner if you are pregnant, or plan to become pregnant, or if you are using any other medications. 

• Aspirin Sensitivity: Individuals with a known sensitivity or allergy to aspirin should avoid white willow bark due to the presence of salicylates.

• Medical Conditions: People with certain medical conditions, such as bleeding disorders, kidney disease, or stomach ulcers, should exercise caution and consult with a healthcare professional before using white willow bark.

• Medication Interactions: White willow bark may interact with medications that slow blood clotting (anticoagulants), as well as other medications containing salicylates.

• Special Populations: The use of white willow bark is not recommended for children, pregnant women, or nursing mothers due to safety concerns and a lack of reliable data. In children, there is a concern that, like aspirin, it might increase the risk of Reye's syndrome in the context of a viral infection.
