Excessive Hair Growth in Women
Experiments in modifying the amount of androgen levels in women who have an excessive amount of hair is reported by the USNLM at https://www.ncbi.nlm.nih.gov/pubmed/17310494. Researchers in Turkey conducted controlled experiments on 21 hirsute female patients by applying findings from previous tests on laboratory rats. The women drank Spearmint tea twice a day for five days as part of a specially designed program of treatment. The results showed that spearmint has potential as an alternative to other forms of antiandrogenic treatment when hirsutism is in a mild form. The report indicates that further testing is required to validate the results of the study prior to recommending spearmint as a drug to reduce the incidence of hirsutism (excessive hair growth in women).
