When something is applied to the soles of the feet, it reaches all the tissues of the body within 20 minutes, and the structure of the skin of the soles of the feet is different from the skin of other parts, and it has the characteristic of absorbing things into the blood like a straw. The skin of the soles of the feet and the palms of the hands has no sebaceous glands at all, so it has been proven that there are 7,200 nerve endings in the soles of the feet, which are able to absorb oil quickly, and that the soles are connected to the thoracic cavity and the middle part to the stomach and digestive organs. Applying oil and massaging your feet is a way to improve the health of body parts. Also, the beneficial oil applied to the feet does not carry the risk of going to the liver and spreading to the entire body through the circulatory system. Add 2-3 drops of essential oil to the massage oil and massage the soles of the feet.
