Online Medicine Resource: Red Clover

Historically, red clover has been used for cancer and respiratory problems, such as whooping cough, asthma, and bronchitis.
Current uses of red clover are for menopausal symptoms, breast pain associated with menstrual cycles, high cholesterol, osteoporosis, and symptoms of prostate enlargement.

The flowering tops of the red clover plant are used to prepare extracts available in tablets and capsules, as well as in teas and liquid forms.

Although several small studies of red clover for menopausal symptoms had mixed results, a large study found that red clover had no beneficial effects on menopausal symptoms.
There is not enough scientific evidence to determine whether red clover is effective for any other health conditions.
NCCAM is studying red clover to learn more about its active components and how they might work in the body, including a clinical trial investigating the safety and effectiveness of red clover for menopausal symptoms.

Red clover seems to be safe for most adults when used for short periods of time. No serious adverse effects have been reported.
Because red clover contains oestrogen-like compounds, there is a possibility that its long-term use would increase the risk of women developing cancer of the lining of the uterus. However, studies to date have been too brief (less than 6 months) to evaluate whether red clover has oestrogen-like effects on the uterus.
It is unclear whether red clover is safe for women who are pregnant or breastfeeding, or who have breast cancer or other hormone-sensitive cancers.
Tell your health care providers about any herb or dietary supplement you are using, including red clover. This helps to ensure safe and coordinated care.
