The Frauenmond bar designed by Marc Widmer contains special ingredients that help women during menses.
The combination of 17 herbs and 60 percent chocolate increase the serotonin levels in the body, according to Kidspot. This increase leads to an elevated mood and feeling of calm.
Chocolate with Love is the Lucerne-based company supplying the bars, which retail for about £10.
On its website Mr Widmer explained: "Cocoa contains rich ingredients such as theobromine and the happiness hormone serotonin. This has a positive effect on the heart and circulation and promotes overall well-being. It gives eating chocolate twice as much pleasure. We hope that you enjoy eating the chocolate as much as we have enjoyed making it."
‘Frauenmond roughly translates to ‘Women’s moon’ though the bar is not just restricted to women. Cocoa, the main ingredient is a mood elevator and is believed to ease pain.
The name Frauenmond roughly translates to 'Women's moon'. He advised the product isn't just restricted to women - men can eat it too. "Of course men can also eat the chocolate. I myself have already tried."
Speaking to local newspaper 20 Minuten, he said: "We want to make the menstruation days of women more comfortable.
Chocolate is known to provide many health benefits, including helping to prevent memory loss.
Dr Sally Norton of Vavista.com said: "Scientists at Harvard Medical School suggest that drinking two cups of hot chocolate a day may keep the brain healthy and prevent memory decline in older people by preserving blood flow in working areas of the brain."
Cocoa also reduces blood pressure - numerous trials have shown that even small amounts of chocolate will produce this effect.
