[Da Jupi Tang (Great Tangerine Peel Decoction)] (from *Ju Fang*) treats internal attack of damp-heat, resulting in fullness and distension of the heart and abdomen, difficult urination, and loose diarrhea. (Because fluids from the lower orifice merge into the large intestine, difficult urination and loose diarrhea occur.) It also treats conditions such as edema.
Shihuashi (Talcum, 6 qian), Gancao (Licorice Root), Chifuling (Red Poria, 1 qian), Zhuling (Polyporus), Zexie (Alisma), Baizhu (Atractylodes Macrocephala Rhizome, stir-fried with soil), Rougui (Cinnamon Bark, 5 fen), Chenpi (Tangerine Peel, 1.5 qian), Muxiang (Aucklandia Root), Binglang (Areca Seed).
Chifuling, Zhuling, and Zexie drain fire and promote water metabolism; Baizhu tonifies spleen qi; Rougui transforms qi and promotes water metabolism. These five herbs constitute Wuling San (Five-Poria Decoction). Shihuashi clears heat and promotes dampness drainage; Gancao drains fire and harmonizes; combined with Chenpi to regulate qi, and Muxiang and Binglang to move qi and guide stagnation, they collectively facilitate the free flow of water passages.

[Bazheng San (Eight-Utensils Powder)] (from *Ju Fang*) treats damp-heat pouring downward, causing dry throat and thirst, urgency and fullness in the lower abdomen, and complete urinary retention. (Damp-heat pouring downward causes lower abdominal fullness; logically urination should be smooth, but sudden retention occurs due to heat constipation.) It also treats strangury with pain and hematuria, or edema caused by heat.
Cheqianzi (Plantago Seed), Mutong (Akebia Stem), Qumai (Dianthus Herb), Pianxu (Persicaria Herb), Shihuashi (Talcum), Gancao Gao (Licorice Root Tip), Zhizi (Gardenia Fruit, stir-fried until black), Dahuang (Rhubarb Root and Rhizome). Decoct with Dengcao (Juncus Effusus Pith); another version adds Muxiang (Aucklandia Root).
Mutong and Dengcao clear lung heat and descend heart fire. The Lung is the origin of qi transformation, and the Heart is interiorly-exteriorly related to the Small Intestine. Cheqianzi clears liver heat and unblocks the Bladder; the Liver meridian distributes around the genitalia, possessing the function of dissipating nodules.

[Danggui Niantong Tang (Angelica Joint-Pain Relieving Decoction)] (from Li Dongyuan) treats intermingling of damp-heat, causing vexing pain in limbs and joints, and heaviness in the shoulders and back. It also treats generalized body pain, or gouty swelling and pain, with continuous purulent discharge from the feet and knees. Furthermore, it treats jaundice caused by damp-heat, where the pulse is deep, solid, tight, rapid, moving, and slippery. (Dampness causes swelling, heat causes pain. Sores and swelling of the feet and knees are mostly due to damp-heat sinking downward; jaundice results from damp-heat steaming and steaming the Spleen and Stomach. Gout is primarily associated with water-dampness, but may also involve wind or cold. When damp-heat prevails and causes disease, it may form edema, or red swelling and erysipelas, or act like hernia attacking up and down; all these can be treated with modifications of this decoction. The anterior aspect of the limbs belongs to the Yangming Meridian, the posterior-lateral aspect to the Shaoyang Meridian, the medial aspect to the Jueyin Meridian, the anterior-medial aspect to the Taiyin Meridian, and the posterior-medial aspect to the Shaoyin Meridian. By hanging the arms close to the body, the position of the thumb helps determine the meridian pathways. For pain in the hands and feet, one must distinguish which meridian is involved and use herbs of that meridian as guiding agents to circulate qi and blood for recovery. For the Taiyang Meridian, use Qianghuo (Notopterygium Rhizome), Fangfeng (Saposhnikovia Root), Shengma (Cimicifuga Rhizome), Baizhi (Angelica Dahurica Root), Gegen (Pueraria Root); for the Shaoyang Meridian, use Chaihu (Bupleurum Root); for the Jueyin Meridian, use Wuzhuyu (Evodia Fruit), Chuanxiong (Ligusticum Rhizome), Qingpi (Young Citrus Peel); for the Taiyin Meridian, use Cangzhu (Atractylodes Lancea Rhizome), Baishao (White Peony Root); for the Shaoyin Meridian, use Duhuo (Angelica Pubescens Root), Xixin (Asarum Root).)
Yinchen (Artemisia Capillaris Herb, wine-fried), Qianghuo (Notopterygium Rhizome), Fangfeng (Saposhnikovia Root), Shengma (Cimicifuga Rhizome), Gegen (Pueraria Root), Cangzhu (Atractylodes Lancea Rhizome), Baizhu (Atractylodes Macrocephala Rhizome), Gancao (Licorice Root, honey-fried), Huangqin (Scutellaria Root, wine-fried), Kushen (Sophora Root, wine-fried).
Qianghuo penetrates the joints, and Fangfeng disperses retained dampness, serving as the sovereign herb. Shengma and Gegen have light aromas, guiding the medicinal action upward; bitter substances disperse pathogenic factors. Baizhu is sweet, warm, and balanced; Cangzhu is pungent and dries the spleen, jointly strengthening the stomach and spleen.
