Active Components and Constitutional Formula
Rhodiola contains a number of potentially active compounds, including phenylpropanoids (rosavin, rosin, rosarin); phenylethanol derivatives (salidroside, tyrosol); flavonoids (rodiolin, rodionin, rodiosin, acetylrodalgin, tricin); monoterpenes (rosiridol, rosaridin); tritrpenes (daucosterol, beta-sitosterol); and phenolic acids (chlorogenic, hydroxycinnamic, and gallic acids). The presence of rosavin distingusihes the species R.rosea from other rhodiolas, and many products are standarized to rosavin content to ensure that they contain the proper species.

Indications and Usage
There are numerous animal and test tube studies showing that rhodiola has both a stimulating and a sedating effect on the central nervous system; enhance physical endurance; improves thyroid, thymus, and adrenal function; protects the nervous system, heart and liver; and has antioxidant and anticancer properties.
According to the result of a research concerning physical duration, the swimming time of mice was prolonged to 135-159% after intake of Rhodiola. Based on another research, intake of standardized Rhodiola Extract improved the physical condition, neuro-sports ability, mental condition and overall healthy sense of the students. The targets under treatment also felt improvement from tireness, insomnia, emotion instability and lack of original motives.
Rhodiola has a more stimulating effort at lower amounts, and a more sedating effect at higher amounts. In medical treatment, the usual amounts taken are 200 to 600mg per day of a standardized extract to at least 3% rosavins and 0.8% to 1% salidroside, Rhodiola Extract is usually taken before meal. No side effects or interaction have been reported.
