White Willow Bark Extract

Active Components and Constitutional Formula 

Salicin (C13H18O7) is an alcoholic β-glycoside that contains D-glucose. Salicin is an anti-inflammatory agent that is produced from willow bark.

Salicin is closely related in chemical make-up to aspirin and has a very similar action in the human body although it is considered better than aspirin as it has a higher bioavailability and it does not cause gastric bleeding . When consumed, it is metabolized to salicylic acid. Salicin elicits bitterness like quinine, when consumed.

Indications and Usage  

White Willow Bark contains salicin, which the body converts to salicylic acid and has the same effect on the body as aspirin without any of the side effects. In fact, White Willow Bark was the basis for the synthesis of aspirin. History of usage of White Willow Bark goes back as far as 500 BC when ancient Chinese healers began using it to control pain. Native Americans also discovered the value of the Willow tree for relieving pain from headaches and rheumatism and reducing fevers.


The benefits of White Willow Bark today are that it is an anti-inflammatory, a fever reducer, an analgesic, an anti-rheumatic, and an astringent. Specifically, it helps to relieve headaches; helps to ease pain associated with inflammatory conditions like rheumatism, arthritis, and carpal tunnel syndrome; and helps to control fevers. Studies have shown that if you feel better, you are more likely to want to stick to your weight loss plan and because of that, White Willow Bark can aid in your diet goals. 


Salicin safely be taken long-term at recommended doses. Higher than commonly recommended doses of this herb can cause stomach upset, nausea, or tinnitus (ringing in the ears). If any of these reactions develop. Stop taking the herb.

Avoid white willow bark, which can irritate the stomach, if you are sensitive to aspirin, or if you have an ulcer or other gastrointestinal disorder.

As with aspirin products, never give white willow bark to children or teenagers under age 16 with symptoms of the cold, the flu, or chicken pox. Although white willow bark is unlikely to cause the rare but potentially fatal condition called Reye’s syndrome in such cases—it is metabolized differently than aspirin—the similarity to aspirin is close enough to warrant caution.
