Prevention of Varicose Veins
Abstract: Varicose veins are abnormal, dilated blood vessels caused by weakening in the vessel wall. Such conditions that increase pressure on the leg veins such as overweight, lack of exercises, hormonal fluctuations during pregnancy and menopause, smoking; constipation or people who have prolonged standing or sedentary position or repeated heavy lifting make veins of legs very weak and develop into varicose veins. Researchers report that a mild care of varicose veins …

Effect of Panchtikt Ksheer Basti in Management of Avascular Necrosis of Head of Femur (Case Study)
Abstract: AbstractAvascular necrosis (AVN) is temporary or permanent loss of blood supply to bone. Without blood, the bone tissue dies and ultimately the bone may collapse. Without treatment, the process is almost always progressive, leading to joint destruction within five years. AVN accounts for more than 10% of total hip replacement surgeries performed. A diagnosed case of male patient with complaint of severe pain in right hip joint and upper aspect …
