Excerpt from Dr. Susan Lark’s Healing Herbs for Women
Chaste tree berry also inhibits the release of follicle-stimulating hormone (FSH). FSH is needed to stimulate estrogen production during the first half of the menstrual cycle. The end result is to promote the estrogen-to-progesterone ratio in favor of progesterone.
Consequently, chaste tree berry can help normalize the secretion of hormones and bring estrogen and progesterone levels into a healthful balance. This makes it a useful treatment for conditions related to estrogen excess, such as PMS and perimenopause.
Suggested Dosage: The dosage for chaste tree berry is 20 mg of the standardized extract, taken twice a day, in the early morning and evening. It is also manufactured as a 10:1 extract. If taken as a liquid, a typical dose is 1 ml once or twice a day. One milliliter is equal to one full dropperful of the herb in a 1 oz. bottle. It may take a while for the benefits of chaste tree berry to manifest, typically about three months or so.
For more information about chaste tree berry or other herbs that help to promote progesterone production or balance estrogen and progesterone, see my book Dr. Susan Lark’s Healing Herbs for Women available on Amazon, AmazonKindle and Womens Wellness Publishing.
