What Are The Side Effects Of Chasteberry?
1. May Cause Acne

Acne is among the most common adverse effects of chasteberry (2). The herb also causes an erythematous rash, which is redness of the skin characterized by increased blood flow to the superficial capillaries. These side effects are usually mild and may go away once you stop using chasteberry (2).
2. May Cause An Upset Stomach

Chasteberry has often been used to treat constipation in traditional medicine (3). Hence, overuse of chasteberry may cause an upset stomach (4). Further, in rare cases, chasteberry seeds may form a mass called a phytobezoar, creating an obstruction. This happens when undigested material builds up in the digestive tract. It usually forms in the stomach but sometimes may reach the colon, causing blockages or even serious complications that require surgery (3).
Other related gastrointestinal complaints might include nausea, leading to fatigue. However, these mild side effects are usually reversible and may go away once you stop using chasteberry (2).
3. Can Lead To Issues During Pregnancy And Breastfeeding

The use of chasteberry during pregnancy and breastfeeding is controversial. There is poor evidence to support if the use of chasteberry during pregnancy can actually prevent miscarriages. A review examined different studies on chastetree (Vitex agnus-castus) to determine the same. It found that although evidence is weak, some studies suggest that chasteberry may influence hormone levels, stimulate the uterus, regulate periods, or even prevent miscarriage. However, experts disagree on whether it increases or decreases milk production (5).
In another study, 352 breastfeeding mothers took chasteberry. Out of them, 15 mothers experienced side effects like itching, rashes, hives, or an early period. So, it is best to avoid chasteberry while breastfeeding (2).
Though in certain small studies, the use of chasteberry seemed to help achieve pregnancy, its use during pregnancy and breastfeeding is thoroughly discouraged as its effect on babies has not been well documented (6)
4. May Cause Problems During Breast Cancer

Chastberry has phytoestrogenic properties (5). It can mimic the effects of estrogen in the body, a hormone that plays a role in the development of women’s breasts. This way, it might cause breast tenderness or interfere with certain cancers. Hence, individuals with hormone-sensitive cancers, like that of the breast, must consult their doctor before using it (7).
5. Can Interfere With Certain Drugs And Therapies

Chasteberry can interfere with birth control pills. It is known to promote fertility, and the herb may not be a good option if you are looking for birth control (8), (7).
Chasteberry can also disrupt progesteronei An ovarian hormone that plays a crucial role in the menstrual cycle and the maintenance of the early stages of pregnancy. , a hormone used in hormone replacement therapyi A treatment that boosts a woman’s hormone levels to relieve menopausal symptoms like hot flashes, mood changes, and night sweats. (9). Hence, women undergoing therapy must steer clear of the herb and talk to their doctor.
Simultaneous use of chasteberry along with antipsychotic drugs is contraindicated (10). Antipsychotic drugs are used to treat psychosis, a mental disorder that makes you feel disconnected from reality (11). Chasteberry may also interact with medication used to treat Parkinson’s disease, a brain disorder that leads to slow movement and balance issues (7), (12). It may also increase the effects of beta-blockers (medicine for conditions like irregular heartbeat and chest pain) and high blood pressure medication (13).
We have seen the major side effects of chasteberry. Research is ongoing, and its use during pregnancy and breastfeeding is not well documented. So, always consult a doctor before consuming chasteberry. They can recommend the appropriate dosage. For you based on your health condition. Learn more below!
Chasteberry Dosage Guidelines
The dosages of chasteberry used in studies vary widely.
- The ideal dosage of the herb extract is between 20 to 40 milligrams per day (6).
- If you are using a fluid extract, the ideal dosage is 40 drops per day (6).
- For the tincture, 35 to 45 drops, thrice a day, should be ideal (6).
Anything beyond this may cause problems.
Chasteberry may also cause side effects when taken with certain birth control options due to the hormonal changes they cause. A blogger had severe mental health issues that she attributed to chasteberry. She knew these mental health issues were caused by hormonal fluctuations, as she had been told so by a doctor when she had experienced similar adverse reactions using a birth control ring and patch. So when she faced a similar depressive episode, she knew something was affecting her hormones and discovered it was the vitex supplement she was taking. She writes, “Vitex is often recommended by Chinese herbalists to regulate menstrual cycles. It should not be taken with the pill as it may increase the side effects and decrease its effectiveness. Needless to say it increased the side effects x100 for me. I am no herbalist or doctor, but if you tend to react badly to the pill or hormones in general then please stay away from this one (i).”
If your doctor permits, you can easily buy chasteberry supplements in the form of capsules, powder, etc. However, you should purchase products with pure extract free from fillers, artificial additives, or preservatives. Also, look for reputable brands with transparent ingredient sourcing that also offer third-party testing to ensure purity and potency. You may also prepare chasteberry tea or smoothie at home.
