Chaste tree extract is widely prescribed in the management of both physical and emotional symptoms associated with PMT. Symptoms can include mood swings, trouble sleeping, inability to concentrate, tiredness, acne, breast tenderness, irregular periods, headaches, and bloating. Several studies have provided evidence supporting the efficacy of Chaste tree in alleviating these symptoms.
In one study, participants were administered 20 mg of Vitex extract daily for three months. The results showed significant improvements in various PMT symptoms including irritability, mood swings, headaches, bloating, and breast fullness. Another study observed similar outcomes over three menstrual cycles in women experiencing moderate-to-severe PMT. Those taking Chaste tree extract showed a notable reduction in negative symptoms, water retention, food cravings, and pain compared to the placebo group by the end of the third cycle.
Fertility
Chaste tree has garnered attention as a potential natural remedy for enhancing fertility, especially in individuals with conditions such as luteal phase defect (LPD) that may be attributed to elevated prolactin levels. Through its ability to regulate prolactin levels and promote a balance between progesterone and oestrogen, Chaste tree has been investigated for its fertility-boosting properties.
In a randomised controlled trial involving 96 women with fertility disorders, those receiving an herbal formula containing Chaste tree twice daily for three months showed higher pregnancy rates compared to the placebo group. Notably, women with conditions like amenorrhea or LPD experienced more than double the rate of pregnancy in the treatment group compared to the placebo.
Menopause
Clinical research suggests that an eight-week regimen of Chaste tree improves anxiety and vasomotor dysfunction by 76% and 88%, respectively, in menopausal women. Many studies investigating the benefits of Chaste tree for managing menopausal symptoms involve combining it with other herbs. For instance, a study incorporating pre- and post-menopausal women administered an herbal formula containing various herbs, including American ginseng, black cohosh, dong quai, milk thistle, red clover, and chaste tree berry for three months. Women taking part in the study reported significant reductions in hot flushes, night sweats, and sleep disturbances following the supplementation.
