HERBAL FACTORS - Black Cohosh - 90 Capsule(s) - NPN: 80010409 -- As women age, production of estrogen tends to decrease while production of luteinizing hormone (LH) increases. This hormonal imbalance is what leads to the symptoms associated with perimenopause and menopause. High levels of LH are linked to night sweats, hot flashes, palpitations and thinning of the vaginal walls. Black cohosh (Cimicifuga racemosa) is one of the most popular and effective and supportive herbal remedies for menopause due to its hormone-balancing, analgesic, and anti-inflammatory properties. It has been clinically shown to help relieve symptoms associated with menopause. The herb contains multiple active ingredients, including triterpene glycosides, anti-inflammatory salicylic acid (the base for the active ingredient in aspirin), aromatic acids, tannins, and resins. A phytoestrogen, black cohosh has effects similar to estrogen and may interact with estrogen receptors, making it helpful for restoring the delicate balance between estrogen and progesterone. Black Cohosh helps restore balance of hormone levels for effective relief from the symptoms of menopause and perimenopause. Natural Factors Black Cohosh delivers 40 mg of standardized herb per capsule to guarantee 2.5% tripterpene glycosides, the main active constituent in black cohosh responsible for balancing hormones and relieving symptoms.
