7 betel nuts, 30g each of dried tangerine peel and papaya, 6g evodia fruit, 15g platycodon root, 15g fresh ginger (with skin), 9g perilla stem and leaves.

bubble_chart Preparation and Dosage

Grind the above ingredients into coarse powder and divide into eight doses. Soak overnight in 750 ml of water, then simmer over low heat until reduced to 375 ml. Remove the dregs, add 500 ml of water to the residue, and simmer again to obtain 200 ml of liquid. Combine the two decoctions and place by the bedside. The next day before dawn, take the mixture in two or three doses, preferably cold, though slightly warmed in winter is acceptable. After taking, consume some pastries to settle the stomach. If not all is consumed, the remainder can be taken gradually the next day. By dawn, a bowl of black stool should be passed, indicating the expulsion of cold-damp toxins from the kidneys. Pain and swelling should subside by breakfast time. Wait until the medicine's effects have passed before eating.

bubble_chart Formula Principles

In the formula, Areca Seed, being heavy in nature, descends and moves qi to expel dampness, serving as the sovereign; Flowering Quince Fruit eliminates dampness and unblocks collaterals, while Dried Tangerine Peel regulates qi and dries dampness, acting as ministers; Perilla Leaf and Platycodon Root unblock qi movement, and Evodia Fruit and Fresh Ginger Rhizome warm and disperse cold pathogens, serving as assistants. When these herbs are combined, they collectively achieve the effects of moving qi to descend turbidity and eliminating dampness to unblock collaterals.
