Product Details


Salicin is a bitter white crystalline glucoside, found in the bark and leaves and acts as an anti-inflammatory agent in the human body. Salicin was the historical origin of aspirin and is chemically related to it. When consumed, the acetalic ether bridge is broken down. The two parts of the molecule, glucose and salicyl alcohol, then are metabolized separately. By oxidizing the alcohol function the aromatic part finally is metabolized to salicylic acid. Salicin tastes bitter like quinine.

1. treatment of fever, colds and infections

As a "natural aspirin", salicin is used to treat mild fever, colds, infections (influenza), acute and chronic rheumatic discomfort, headache and pain caused by inflammation. Aspirin (acetylsalicylic acid), as a substitute for salicylic acid, has potential gastrointestinal side effects. As its natural configuration, salicylic acid can be converted to salicylic acid through blood and liver through the gastrointestinal system. The transformation takes several hours, so the result is not immediately perceived by the human body, but the general effect will last for hours.

2. alleviated arthritis pain and low back pain

Salicylic acid is considered to be the source of the anti inflammatory and relieving pain of white willow bark. The analgesic effect of white willow bark is usually slower but longer than that of ordinary aspirin. A trial found that a class of herbal compounds containing 100 ng salicylic glycoside could effectively improve the analgesic capacity of patients with arthritis after two months of continuous use. Another experiment found that a daily intake of 1360mg white Salix extract (containing 240mg salicylin) could have a better efficacy in the treatment of joint pain and / or arthritis for two weeks. The use of high-dose extract of willow bark may also help relieve back pain. A four week experiment showed that the extract of Salix peel containing 240mg salicylic acid could effectively reduce the deterioration of back pain.



1. Salicin is used to relieve minor aches and pains, especially those caused by inflammation, to help reduce minor fevers, and as a gastric stimulant.

2. Salicin was used to first produce the drug aspirin, with which it shares many similarities. Both substances, when metabolized in the human body, are partly reduced to salicylic acid. Salicylic acid was studied and found to be an inferior alternative to salicin. Aspirin was developed in an effort to create a similar but more effective compound.
