17 Amazing Benefits & Uses of Chasteberry

by John Staughton (BASc, BFA) last updated -

Chasteberry has been used in traditional medicine for centuries, and while research is still limited, it appears to have certain important health benefits.

What is Chasteberry?

Chasteberry is the fruit of the chaste tree, which bears the scientific name Vitex agnus-castus. Other trees and plants in the Vitex genus are typically tropical in nature, but this species is also found in temperate areas. The tree and its berries have the name “chaste” because the fruit was long believed to be an aphrodisiac. The effects that this plant can have on the reproductive health of both men and women is largely why it remains in use to this day. [1]

While chasteberries are perhaps the most well-known part of the plant, the flowers, leaves, and tender shoots are also used in certain medicinal applications. Some of the active ingredients from these berries have been utilized in more formal medicine, specifically to regulate female hormonal health, but there is still some debate about the efficacy of this tree and its fruits.

  • For a liquid extract, 30-40 drops each morning should be sufficient.

Regardless of why you are choosing to use this herbal remedy, it is best to speak with your doctor before beginning a new treatment.
