Dose:

Comment:
Tabanus is considered stronger than Leech to break blood stasis and resolve masses, however, it has a shorter lasting effect. Leech is considered to have a long-lasting, more sustained effect. Therefore, they work well together, especially in fixed abdominal masses and Tumors.
Preparation:
1. Stir-fried or Baked Gad Fly:
They are generally baked until brown and crispy, then remove the legs and wings. This facilitates powdering, lessens their foul smell, and reduces toxicity.
2. "When they bite oxen and horses, wait until their abdomen is filled, squeeze them to remove the blood, and dry them". (Ben Cao Gang Mu)
Decoction: 1500mg–3 grams
