The inner bark contains tannins, flavonoids, phenolic glycosides, and anti-inflammatory and fever-reducing salicylates. The high concentration of tannins may be responsible for relieving gastrointestinal disturbances and reducing tumors of the esophagus, stomach, colon, and rectum.
White willow's analgesic effect works to inhibit the production of prostaglandins, a hormone-like chemical that is produced by the body in response to injury and causes aches, pains, and inflammation. Thus, white willow is beneficial in treating acute and chronic pain and inflammation in conditions such as painful menstruation, arthritis, and neuralgia. White willow is best when used over long periods of time and can take days to improve conditions.
The active ingredient in white willow is salicin. Salicin is gradually converted along with other compounds in white willow into salicylic acid in the intestine and liver. Because of this conversion process, white willow generally takes longer to act than aspirin, but the effects may last for an extended period of time. As a result, white willow is mild on the stomach and usually does
not cause bleeding or other gastrointestinal discomfort that often occurs with aspirin usage.
Herbalists claim that white willow can sometimes be used in the same conditions as aspirin. One benefit to white willow use is that the natural salicylic acid present in white willow reportedly produces fewer side effects than the synthetically produced acetylsalicylic acid of aspirin.
Aspirin has been recommended as a treatment to reduce the risk of heart attacks and stroke by lessening the chance of internal blood clots. Preventative benefits of white willow in these cases have not been determined, primarily because the salicin content of the bark varies. Herbal experts believe that most willow bark samples contain enough salicin to have a similar effect.
The bark of young tree branches (two or three years old) is harvested during the early spring. The grayish bark
The recommended daily dosage is 100–250 mg of white willow every four hours. To relieve arthritic, back, and muscle aches and pains, the recommended dosage is 225 mg of white willow bark four times daily.
A decoction made from willow bark is used both internally and externally. To make a decoction, combine 1 tsp chopped or powdered white willow bark with 8–10 oz of water. Bring to a boil, then simmer for five minutes. Drink three or four times daily. This mixture can also be gargled to help inflamed gums and tonsils. Cooled and applied externally, the decoction helps aid healing of sores, burns, or cuts.
Tincture dosage: 2 ml three times daily.
