Analysis and testing have determined that medical stone is a type of subvolcanic rock ore, containing over 20 trace elements beneficial to human health, including iron, magnesium, potassium, sodium, calcium, manganese, zinc, phosphorus, silicon, and sulfur. Medical stone has a sweet, warm nature and is non-toxic. It is primarily used to treat various carbuncles and deep-rooted boils, has a certain therapeutic effect on vascular sclerosis in the elderly, and possesses diuretic, stomach-strengthening, and liver-protecting functions. Medical stone can adsorb bacteria and germs on the surface of the human body. It promotes recovery from skin conditions such as dermatitis, itching, and dry skin, while also adsorbing dirt, keratinized skin, and excess fat from cells on the skin's surface, restoring skin elasticity. Additionally, it can adsorb various toxins excreted from the body, beautifying the skin. It is known as a health-protecting medicinal stone. Water soaked with medical stone is equivalent to mineral water, and medical stone is also an excellent natural food preservative and deodorizer for refrigeration.
