Sanamaki, also known as Senna or Sana Makki, is a natural herb used primarily for its strong laxative properties to relieve occasional constipation. It contains compounds called anthraquinones that stimulate the intestines, aiding bowel movements and potentially assisting with detoxification and temporary weight loss. While it also has some anti-inflammatory effects and can be used to treat certain skin problems, its use should be cautious, especially for weight loss, and ideally under medical guidance.
