Miswak is a teeth-cleaning stick derived from the Salvadora persica tree, commonly known as the "toothbrush tree." It has been used for oral hygiene for centuries, especially in the Middle East, Africa, and South Asia. Miswak contains natural antibacterial properties, which help reduce plaque, fight gum disease, and freshen breath. It's a traditional, eco-friendly alternative to modern toothbrushes, offering both mechanical and medicinal benefits for oral care.
