Pharmacological Effects of Tou Tong San

Tou Tong San (Headache Powder) is generally effective in promoting blood circulation, removing blood stasis, dispelling wind, and relieving pain.

1. Promoting Blood Circulation and Removing Stasis: When patients experience headache, Tou Tong San can effectively treat migraine and symptoms associated with blood stasis. It also exerts wind-dispelling and analgesic effects. The main active ingredients in Tou Tong San include caffeine, aspirin, and acetaminophen. Combined, these three components confer additional benefits, including antipyretic, analgesic, and anti-inflammatory effects.

2. Dispelling Wind and Relieving Pain: After administration, Tou Tong San effectively dispels wind and alleviates pain. Clinically, it is commonly used to treat migraine. However, long-term use of Tou Tong San for chronic migraine may lead to adverse effects, including hepatic injury, allergic reactions, and increased metabolic/excretory burden. Potential adverse reactions also include urticaria, skin rash, headache, and asthma.
