Kali-Sulph #7 oxygenates the tissue salts, keeping the different salts active. It is also part of skin cells and internal organ linings. It is good for joint pain, feeling of heaviness and hair loss. A German homeopathic physician, Dr. Schussler, identified 12 cell salts (mineral salts) that were all that was needed to maintain the body in perfect health and balance. A lack of a specific cell salt would result in a deficiency that would eventually lead to a symptom and possibly disease. By replacing the deficient cell salt, the balance was restored and healing took place.
