With respect to the high incidence of hot flash in postmenopausal women and the controversies regarding its treatment, this double-blind clinical trial was conducted to determine the effects of Pimpinella anisum on hot flashes in these women referring to rural and urban health centers of Qazvin Province in 2009.

Seventy-two women with hot flashes were randomly selected according to the predetermined criteria and divided into two experimental and control groups. Their medical records at health centers were used for sampling.

Each woman in the experimental group took a capsule containing 330 mg Pimpinella anisum 3 times a day while in the control group, women took 3 capsules, each containing 330 mg potato starch, over 4 weeks and after that, they were following up for 4 weeks. Before taking the capsules, they were assessed for 2 weeks about the frequency and severity of hot flashes. Data were collected through a questionnaire and an information form. Content validity method was used for validity of the tools. ANOVA and Student›s t-test were applied for statistical analysis.

In the experimental group, the frequency and severity of hot flashes before the treatment were 4.21% and 56.21% and, after that, were 1.06% and 14.44% at the end of the fourth week respectively. No change was found in the frequency and severity of hot flashes in the control group. The frequency and severity of hot flashes was decreased during 4 weeks of follow up period.

P. anisum is effective on the frequency and severity of hot flashes in postmenopausal women.
