Thai massage balls, also known as herbal compress balls or herbal balls, are made of a combination of herbs and other natural ingredients that are wrapped in a cloth or muslin ball. The herbs used in the compresses can vary depending on the specific recipe, but commonly include lemongrass, ginger, turmeric, kaffir lime, camphor, and other aromatic herbs. These herbs are known for their anti-inflammatory, analgesic, and muscle-relaxant properties, making them a popular choice for massage therapy.

The compress balls are typically heated with steam or in a microwave and then used during a Thai massage or other types of massage therapy. The heat from the compresses, combined with the therapeutic properties of the herbs, can help to relieve muscle tension, reduce pain and inflammation, and promote relaxation and overall wellbeing.
