Rating (out of 5): 2

Chaste tree (Vitex agnus-castus) has a long history of use in traditional and herbal medicine, particularly in Europe and the Mediterranean region, for various gynecological conditions, including menstrual irregularities and supporting fertility. Its use for miscarriage prevention is primarily grounded in traditional practices rather than robust modern scientific validation. Historically, chaste tree was believed to balance female hormones, notably by influencing the pituitary gland to promote progesterone production. Progesterone is crucial in maintaining a healthy pregnancy, especially in the early stages, and low levels are associated with an increased risk of miscarriage.

Traditional herbalists have recommended chaste tree for women who experience recurrent miscarriages believed to be due to luteal phase defects (a disorder characterized by insufficient progesterone production). Some small studies and anecdotal reports suggest that chaste tree may help regulate menstrual cycles and improve luteal phase length, which in turn could theoretically reduce miscarriage risk in women with diagnosed progesterone deficiency. However, there are no large, well-designed clinical trials specifically confirming its efficacy in preventing miscarriage. Most supporting evidence remains anecdotal or based on traditional use.

In summary, while chaste tree is traditionally used for supporting female reproductive health and has some preliminary evidence suggesting hormonal benefits, its use for miscarriage prevention is not strongly supported by modern scientific research. Consultation with a healthcare provider is essential before using chaste tree for this purpose.
