Pygeum in Herbal Medicine: Properties of Pygeum
This plant has been shown to possess, through several pharmacological studies, an anti-edema activity (by inhibiting the synthesis of prostaglandins and leukotrienes). It also contributes to increasing bladder elasticity and helps in the treatment of prostatic hypertrophy. The plant is not toxic and is commercially available as a medicinal product for oral administration.
Daily dose: 75-200 mg of lipidosterolic extract, in divided doses, to be taken with food or milk to minimize gastrointestinal effects.
