Mugwort ash has antibacterial and anti-inflammatory properties, stopping bleeding and astringent sores, and is mainly used in the treatment of bleeding sores, foot eczema and other diseases. Modern clinical research suggests that mugwort ash can be used for the prevention and treatment of decubitus ulcers. The external application of mugwort ash can effectively promote the healing of bedsores, shorten the course of the disease and reduce pain. The liner made of moxa ash is significantly better than the traditional rubber air cushion in terms of anti-infection, maintaining local dryness, and comfort. Moreover, studies have shown that the exudate from bedsores after moxibustion alone dries out quickly and forms a hard, thick scab, while the scabs after moxibustion treatment with moxa ash are thinner and softer, and the healing process is faster than the former. Although moxa ash is more versatile, it should not be used blindly. If you need to use it, it is recommended that you consult a medical professional before using it.
