Androstadienone is a pheromone derived from the male hormone, testosterone. Apparently, its presence on the skin produces a certain natural attraction of men on women. A supplier in the cosmetic industry is selling an ingredient that contains this substance.
The root of Markandi (Coleus forskohlii), a tropical plant used in Ayurvedic medicine, stimulates the synthesis of androstadienone. It is the essential element of the cocktail that could make men more attractive. But the mixture also contains polyphenols from the leaves of black tea (Camellia sinensis), which prevents androstadienone from breaking down, causing it to accumulate and thus increasing its effect. Although there are no independent studies that confirm it, the manufacturers assure that the ingredient is effective if included in after-shave, deodorants, gels and body milks.
