A herbal remedy made from dried fruit extract could help ease the unpleasant period symptoms women suffer each month.
In the days leading up to their periods, millions of women suffer mood swings, headaches and sore breasts.
But scientists think a fruit extract first discovered by Greek sages nearly 2,500 years ago can be used to beat the period blues.
Up to 40% of women suffer from pre-menstrual syndrome (PMS) so badly that they need to go to their GP and up to 2% have to take two days off a month sick.
Dieticians have given the research cautious support, but say they will be recommending women suffering from PMS try the extract.
German Researcher Rued Schellenberg from the Institute of Care and Science, near Frankfurt, found that women taking the fruit extract over three months suffered less from mood swings, anger, headaches and sore breasts than those who did not.
Better known as the fruit of the Chaste Tree.
Grows in valleys and riverbanks of the Mediterranean and Central Asia.
Has delicate violet flowers and finger shaped leaves.
Fruit is the size of a peppercorn and it has the taste and smell of pepper.
