Reflexology evolved in China about 5000 years ago. It is a deeply relaxing treatment which involves massaging and working on pressure points on the feet to clear energy blockages in the body. The soles of the feet contain a number of reflexes and zone that correspond and connect with organs, glands or nerves in the body. It is especially effective for relief of back pain, headaches, fertility problems, hormone imbalances, asthma, insomnia and depression. It soothes nerve endings, boosts the immune system and increases blood flow.
