Though primarily used for the female system, it can be equally beneficial for men. It is known to contain precursors of the oestrogens (female hormones). However, it acts in an amphoteric way to normalise function. The body may use this herb to balance and tone and thus it will aid in apprently opposite situations. Whilst being of help in all uterine problems, it is specifically useful in delayed or absent menstruation (amenorrhoea). Where ovarian pain occurs False Unicorn Root may be safely used. It is also indicated to prevent threatened miscarriage and ease vomiting associated with pregnancy. However, large doses with cause nausea and vomiting.
