How Chinese herbs can help your pregnancy Herbs are used in China and East Asia to treat all aspects of a woman's life, from early childhood, to menstruating, fertility, pregnancy, post labour, menopause and in old age. There are thousands of different herbs that exist in Chinese herbal medicine. Certain herbs are known to have health benefits during pregnancy. Chinese herbs can be used in pregnancy to reduce commonly seen problems, for example slow foetal growth rate, poor energy levels, anxiety, poor sleep, poor appetite, stress and depression. Herbs are safe to take during pregnancy when they are prescribed by a qualified herbalist. I would recommend not buying herbs over the counter to self-medicate.
