About Chasteberry

The chasteberry, or monk's pepper, comes from the chaste tree, which grows in western Asia, southwestern Europe and the southeastern United States. Its use dates back more than 2500 years. It is still used today, sold under the name Vitex agnus-castus.

History

• In the Middle Ages, monks added the chasteberry to their meals, thinking it would stifle their libido; this is likely where the name "monk's berry" comes from. It is believed that the ancient Greeks brewed a beverage from the chasteberry for their wives to drink while they were away fighting wars, in an effort to keep them chaste. The Romans copied this practice and also spread the leaves around their homes, believing the aroma would serve the same purpose.

Early Medicinal Uses

• Aside from squelching sexual desire, chasteberry has been used for thousands of years to alleviate the symptoms of premenstrual syndrome (PMS) and other female problems such as menopause or infertility. Chasteberries were also believed to stimulate the production of milk in nursing women. The seeds were sought for treatment of indigestion, headaches, fevers, diarrhea and colic. Both the seeds and leaves of the chasteberry were used to treat snake and spider bites. Later, the Persians discovered that blending the berries with other herbs created cures for epilepsy, madness and hysteria.

Modern Medicine

• No data exists to support the claim that chasteberry aids in lactation or in controlling sexual libido. Studies have shown some benefits when it is used to treat PMS. Patients with symptoms such as breast pain, irritability, constipation, headache and depressed mood showed some improvement after treatment with the herb. Chasteberry has been widely used in Europe for the last 50 years to treat PMS, menstrual cycle irregularities and cyclical breast discomfort. Germany approves and prescribes the plant for the treatment of these symptoms.

Side Effects

• The use of chasteberry has very few side effects. Most effects are relatively minor. Dry mouth, tiredness, dizziness, headache and gastrointestinal discomfort are occasionally reported. There are no known drug interactions with chasteberry and prescription drugs. Not enough is known about the effects of using chasteberry during pregnancy or breast feeding. Consult your doctor before using chasteberry at these times.

Availablilty

• Chasteberry is available primarily in capsules of 80 to 225 milligrams. The dosage depends on the manufacturer and the number of milligrams per capsule. It is available as an extract, as an extract blended with ground berries to enhance the effect or blended with other supplements such as vitamin B6. Your symptoms and your physician's advice will determine the best choice for you.
