Herbal beauty baths have been used for ages to pamper, treat, and beautify. Chinese medicine has employed herbal baths as far back as the Shang Dynasty (1700 to 1027 BC). The main usage was to relieve stress and slow the aging process. Simply adding herbs to your bath water can help treat just about any beauty problem, and can be very helpful in resting and relaxing the body and skin. Use one or more of these herbs to tighten and tone the skin. Perfect for new mothers trying to tone after pregnancy skin : thyme, lavender (also an antiseptic and stimulates circulation), milfoil, peppermint (also an antiseptic), nettle.
