NEW YORK (Reuters Health) - Pairing up two commonly used
herbal medicines is "very effective" for easing physical and
psychological symptoms of menopause, German researchers report.
St. John's wort is widely used to treat mild to moderate

for menopausal complaints, Dr. Joerg Gruenwald of Analyze &
Realize, a Berlin-based botanical consulting company, and
colleagues write in the February issue of Obstetrics &
To see if a fixed combination of the herbal medicines could
offer an alternative to hormone replacement therapy, the
researchers studied 301 women who had been experiencing
menopausal symptoms for at least three months, along with
depressed mood. Half took the St. John's wort and black cohosh

Study participants took the two tablets twice a day for the
first eight weeks of the study, and once daily thereafter.
After 16 weeks, women who took the two-herb combination
