Chaste Berry: Snapshot


One of the few herbal medicines known to have a progesterone-type activity within the body, chaste berry is a specific for menstrual and perimenopausal problems. Vitex increases the production of progesterone, luteinizing hormones, and prolactin and inhibits the release of follicle stimulating hormone. It helps to reregulate the menstrual cycle for women coming off birth control pills. It can help normalize the menses, shortening a long cycle or lengthening a short one. It also helps normalize the functions of the pituitary gland.

Botanical Name

Vitex agnus-castus

Part Used

Berry

Common Names

Agnus castus, Chaste Berry, Chaste Tree, monk’s pepper, Vitex

Brief History

Chaste Berry is a a time tested herbal therapeutic going back so far as 600BC where it’s mentioned in Homer’s Iliad as a symbol of chastity. As the name implies, it was thought to reduce libido and was used for that purpose by medieval monks throughout the centuries as a pepper substitute or as a tea. This peculiar hormonal modulating property has been empirically observed by herbalists and scientifically confirmed by modern science, making Chaste Berry a primary botanical in the herbal medicine chest. But before we get to the uses let’s look at how to grow and keep it.

Cultivation

A deciduous, aromatic tree growing to 7 meters with palm shaped leaves and small lilac flowers in dense clusters to 6 inches followed by little red-black fruits. It blooms in Summer. The entire plant is aromatic, especially the flowers and fruits.Native to the Mediterranean region and western Asia. It is cultivated in subtropical areas around the world, and has become naturalized in many regions.

Chaste Berry

It is grown from seed in spring or autumn. For best seed germination prefers soil temperatures of 15 – 22°C in average, well-drained dry soil. Very drought tolerant. Soil pH of 5.5-8.5. Full sun or partial shade. Can also be propagated by cutting or layering from young woody cuttings. A dip in a rooting hormone and misting cuttings is suggested for optimum propagation. Bottom heat also helps. Cuttings taken once flowering starts do not take as easily. Plant on 6-8 foot centers with a small amount of balanced slow release fertilizer.

Prune back old growth in the late winter since leaves will sprout on new growth. The ripe berries are collected in autumn. The berries are already dry on the plant and can just be stripped with the fingers. To process clean out the few leaves and stems that might be included: only the dried berries are used  for therapeutic purposes

Constituents

Essential oils (cineol, limonene, pinene, sabinene), flavonoids (casticin, isovitexin, orientin), alkaloids (vitticine), iridoglycosides (agnuside, aucubin, eurostoside)

Edible

The seeds can be ground into a peppery condiment.

Hormonal modulator, uterine tonic, galactagogue

Clinical Actions

Dopaminergic, Prolactin inhibitor

Therapeutic Indications

Amenorrhea, cysts (in the breasts, ovaries, and uterus), depression (related to menopause), dysmenorrhea, endometriosis, fibroids (in the breasts, ovaries, or uterus), infertility, herpes (related to menses), menorrhagia, migraines (related to menstrual cycle), polymenorrhea, premenstrual acne, premenstrual syndrome, and threatened miscarriage. It can also be beneficial after hysterectomy.

Primary Uses

Chaste Berry is sometimes called “the women’s herb.” It is used for menstrual cycle irregularities, premenstrual syndrome (PMS), a more severe form of PMS called premenstrual dysphoric disorder (PMDD), and symptoms of menopause. It is also used for treating “lumpy” (fibrocystic) breasts, female infertility and preventing miscarriage in women with low levels of progesterone

Men use Chaste Berry for increasing the flow of urine, benign prostatic hyperplasia (BPH), and for reducing sexual desire.

Hormonal Issues

The most important therapeutic application comes from its ability to normalise the activity of female sex hormones. It is thus indicated for dysmenorrhea (painful periods), pre-menstrual syndrome (PMS), and menopause. Similarly, it may help the body regain hormonal balance faster after discontinuation of oral contraceptives.

Chaste Berry not only eases symptoms of PMS, but also, over time, may actually cure the disorder. PMS has been linked to abnormally high levels of estrogen, and has proved especially helpful for cases in which symptoms tend to disappear when menstruation begins. Positive results may be perceived as early as the second to the third menstrual cycle, but permanent improvement may take up to one year or longer.

Combination idea: Black Cohosh (Cimicifuga racemosa), Dong Quai (Angelica sinensis)

Premenstrual dysphoric disorder (PMDD)

Chaste Berry is about as effective as the prescription drug fluoxetine (Prozac) for relieving symptoms of PMDD. However, it seems to be somewhat more effective for physical symptoms such as breast tenderness, swelling, cramps, and food cravings. Fluoxetine seems to be somewhat more effective for psychological symptoms such as depression, irritability, insomnia, nervous tension, and feeling out of control.

Combination idea: St. John’s Wort (Hypericum perforatum) or Vervain (Verbena spp.) could be an effective choice for a complete address to those issues.

Infertility (Female)

Chaste Berry is the classical first herb to consider for women who are trying to get pregnant as it may effectively regulate the ovulatory cycle as well as stimulate growth of the uterine lining. There is some evidence that taking it can help some women get pregnant. However, it does not seem to work quickly and can take from 3 – 7 months of treatment to achieve pregnancy.

Combination idea: Shatavari (Asparagus racemosus) is a common herb used in Ayurvedic medicine to facilitate fertility.
