Tiger penis is not a traditional medicine for impotence. It is only 4cm long and it would shorten to half of the size when dried, said Huang Lin Huang of the Committee on Chinese Medicine and Pharmacy, Department of Health of Taiwan.
According to the Compendium of Materia Medica (Bencao Gangmu) – the most complete and comprehensive traditional Chinese medicine book – horse and deer penises could revive vitality.
This is a myth. There was no mention of tiger penis in any of the medical books, said Huang. He added that the sexual intercourse time of a tiger was also very short.
