Why Do Purple Bumps Appear When I Hit My Elbow?

The appearance of purple bumps on the inside of the arm after slapping is often caused by the rupture and bleeding of subcutaneous capillaries under external force. As blood leaks out from the ruptured capillaries into the subcutaneous tissue, we can see a bruise on the intact skin. At this point, the leaked blood under the skin is considered a foreign body, and due to the rich nerve endings in the subcutaneous tissue, the pain is usually evident. After 24 hours of the hematoma, warm compresses can be applied to the affected area with warm water to promote local blood circulation and disperse the hematoma. Generally, the hematoma under the skin will be gradually absorbed by the body, and the process may take approximately two weeks.

Actually, slapping the inside of the arm does not detoxify the body. Although slapping is a common technique in traditional Chinese medicine (TCM) massage, its main effects can be summarized as "regulating qi and blood flow, and dredging meridians." This is somewhat similar to other common TCM techniques such as scraping and cupping. Regarding the folk belief that slapping detoxifies, doctors suggest that this is more likely a marketing gimmick used by businesses.

Increasing the intake of whole grains and fruits can promote bowel movement, prevent constipation, and help us eliminate waste and toxins. When our bodies are revitalized internally, we also tend to look more beautiful! It is essential to consume soy milk, vegetables, fruits, green tea, and water regularly. Whole grains (such as beans, corn, and millet), white and black fungus, mushrooms, honey, sesame, red dates, chrysanthemum, seaweed, goji berries, and bone broth should be consumed frequently. These foods are not only nutritious but also effective for detoxification.
