Self-heating wormwood foot and hand warmer patches, known in TCM as Ai Cao (艾草) from Artemisia argyi, are wearable warming pads for the foot sole and wrist. In TCM theory, wormwood is warm in nature and associated with dispersing cold, while these patches use air-activated heat to provide comforting warmth.
