Effects of Chasteberry

Chasteberry is often used to relieve symptoms of menstruation, premenstrual syndrome and menopause because it contains elements that balance the hormones. Because of its therapeutic effect on the female reproductive system, chasteberry is found in homeopathic remedies as well as in allopathic formulas dealing with estrogen and progesterone ratios. Effective during menstruation and premenstrual syndrome, chasteberry has been used for thousands of years to relieve symptoms of discomfort.

History

Chasteberry is known scientifically as Vitex agnus-castus and more commonly as monk's pepper. Used for centuries to ease cramps and stimulate the production of breast milk, it has been found in the annals of medicinal history as far back as Hippocrates in the fourth century B.C.. The ancient Greeks and Romans associated the plant with chastity as well as with warding off evil spirits. In medieval times, monks chewed the leaves of the chasteberry plant to help them stay celibate, hence the correlation with its name.

Characteristics

A small shrub that grows up to 2 feet high, the chasteberry plant is native to tropical and Mediterranean climates, however it can be cultivated in any garden with the right kind of care. The plant produces small violet flowers along with berries that are dried before use. As a phytoestrogen, chasteberry contains flavenoids, glycosides, and other essential oils that help to balance estrogen and progesterone levels. Because of its antioxidant content, it is also able to help neutralize free radicals.

Regulating Estrogen and Progesterone

Chasteberry functions by affecting the hypothalamus and pituitary glands in order to balance hormones. In this way, it is able to regulate estrogen and progesterone production by the ovaries, which is especially effective throughout the menstrual cycle. Generally, progesterone levels lower during menstruation, which results in estrogen dominance. This can lead to abnormal bleeding, be it too light, too heavy, or too frequent, as well as other symptoms of discomfort. Because of chasteberry's ability to raise progesterone levels, it is able to help control cramps, irritability, depression, bloating and other symptoms of menstruation and PMS. Chasteberry is also used to relieve the pain of tender breasts by suppressing the production of prolactin, a hormone that, when elevated during menstruation and PMS, causes tenderness in the area. Chasteberry also eases the uncomfortable symptoms of menopause, such as hot flashes, irregular periods and other discomforts.

Other Benefits

As an anti-inflammatory and antioxidant, chasteberry is also used to help reduce uterine fibroids, reduce epileptic seizures, and improve bone density. According to herbalist and author Christopher Hobbs, chasteberry has positive results when used to treat acne.
In a double-blind study done at the Department of Gynecology/Obstetrics at Stanford School of Medicine in Stanford, California, scientists found that there was an increase in progesterone production when chasteberry was given to 93 women trying to conceive. Chasteberry is associated with helping counteract infertility through its ability to regulate ovulation through hormonal rebalancing.

Using Chasteberry

Chasteberry comes in tablet, capsule, and tincture form. The dried berries can also be brewed as a tea. As with any herbal product, patience is needed as it can take three to six months to feel its effects.

Side Effects

Side effects from taking chasteberry are rare. Because of its role in balancing hormonal function, if it is taken along with birth control pills, it can alter the effectiveness of the treatment. This is also true in the case of combining chasteberry with proscribed estrogen supplements. Side effects can include nausea and stomach upset. As with any formula, it is important to first consult with a health care provider, especially if you are taking other medications.
