Yan Shi Xiongqi Decoction (Szechuan Lovage and Angelica Decoction): Treats vertigo and loss of consciousness caused by excessive blood loss from various sources.
Ingredients: Chuanxiong Rhizoma (Chuanxiong), Danggui Radix (Angelica Sinensis) (soaked in wine, equal parts).
Usage: Cut the herbs into small pieces. Take 4 qian per dose, decoct with water, and take orally.

Liang Fang Zhi Feng Liuhe Tang (Wind-Regulating Six-Harmony Decoction from "Excellent Prescriptions"): Treats vertigo caused by wind deficiency.
Ingredients: Siwu Tang (Four Substances Decoction) plus Qinjiao Radix Gentianae (Gentiana Macrophylla), Qianghuo Rhizoma et Radix Notopterygii (Notopterygium). (See details under the Stroke section).
Note: Both of the above prescriptions are medicines for nourishing blood and harmonizing blood, originating from the treatment principles of the Jueyin Liver channel. However, Xiongui Tang focuses on supplementing the yang within the blood, whereas Siwu Tang supplements both yin and yang. Qinjiao and Qianghuo can be used as assistant drugs (Zuo Shi), but should not be used in equal proportions to the main ingredients.

Zhizhi Fang Xiangju Yin (Aromatic Citrus Drink from "Direct Insights"): Treats vertigo due to Qi deficiency.
Ingredients: Muxiang Radix Aucklandiae (Aucklandia), Baizhu Rhizoma Atractylodis Macrocephalae (Atractylodes Macrocephala), Banxia Qu Fermented Pinelliae (Pinellia Leaven), Jupe Pericarpium Citri Reticulatae (Tangerine Peel), Baifuling Poria (Poria with Hostwood), Sharen Fructus Amomi Rotundus (Amomum), Gancao Radix Glycyrrhizae (Licorice) (roasted with honey), Dingxiang Flos Caryophylli (Clove) (each 1 fen).
Usage: Coarsely crush the herbs. Take 3 qian per dose, decoct with five slices of fresh ginger, and swallow Suhe Xiang Wan (Styrax Pill). If this prescription is modified by adding Chuanxiong Rhizoma (Chuanxiong) and Danggui Radix (Danggui) each 3 qian, and Guigui Cortex Cinnamomi (Cinnamon Bark) 0.5 liang, it treats vertigo due to Blood deficiency.
Note: The book *Zhizhi Fang* states: "Excessive sexual indulgence causes the Kidney organ to fail to grasp Qi and return it to its origin, leading to chaotic Qi rushing upward; this is vertigo arising from Qi deficiency. Hematemesis, epistaxis, and metrorrhagia cause the Liver organ to fail to secure Ying Blood, leading to chaotic bleeding deviating from normal pathways; this is vertigo arising from Blood deficiency." Since it claims that the Kidney fails to grasp Qi, causing Qi to rush upward, how can using these aromatic, drying, acrid, and hot medications truly descend Qi? It also claims Qi deficiency, yet can these medications truly tonify Qi? It mentions Blood deficiency, stating that adding Chuanxiong and Danggui is acceptable, but the added Guigui, Dingxiang, and Muxiang— even if Blood deficiency involves cold deficiency—are difficult to apply universally. What would be the harm if the patient has Heat due to Blood deficiency? Mencius said, "To believe everything in books is worse than having no books at all," which precisely applies to such cases.

Ju Fang Heixi Dan (Black Tin Pill from "Official Formulary"): Treats vertigo and dizziness of the head and eyes caused by failure of Yin and Yang to ascend and descend, characterized by excess above and deficiency below.
Yangzheng Dan (Nourish Righteousness Pill): Treats vertigo and continuous salivation caused by deficient wind. This medication regulates the ascending and descending of Yin and Yang.
Both prescriptions are found in the *Ju Fang*; they should be taken with a decoction of Rushing Xiang Resina Agallochae (Frankincense) soaked in water.

Shunqi San (Qi-Promoting Powder): Treats vertigo and dizziness of the head and eyes caused by constitutional weakness, abundant phlegm-dampness, and stagnant Qi.
Ingredients: Nanxing Rhizoma Arisaematis Preparatum (Prepared Arisaema) (1 liang, processed), Chuanwu Rhizoma Aconiti Kusnezoffii (Kusnezoff Monkshood), Fuzi Radix Aconiti Lateralis Preparata (Prepared Lateral Root of Aconite) (each 0.5 liang), Muxiang Radix Aucklandiae (Aucklandia) (2.5 qian).
Usage: Take 3 qian per dose, decoct with ten slices of fresh ginger.

Yan Shi Chenxiang Cishi Wan (Agarwood and Magnetite Pill by Yan): Treats vertigo, dizziness of the head and eyes, tinnitus, and deafness caused by excess above and deficiency below.
Ingredients: Chenxiang Lignum Aquilariae Resinatum (Agarwood) (0.5 liang, separately ground), Cishi Magnetitum (Magnetite) (calcined, quenched in vinegar seven times, then ground), Hulusba Semen Trichosanthi (Trichosanthes Seed) (stir-fried), Chuanbaji Tian Cortex Morinda Officinalis (Morinda Root Bark) (heart removed), Yangqishi Stilbitum (Stilbite) (processed), Fuzi Radix Aconiti Lateralis Preparata (Prepared Lateral Root of Aconite) (processed), Jiaohong Pericarpium Zanthoxyli (Zanthoxylum Pericarp), Shanzhuyu Fructus Corni (Cornus Fruit), Shanyao Rhizoma Dioscoreae Oppositae (Dioscorea) (stir-fried, each 1 liang), Qingyan Halitum (Rock Salt) (separately ground), Ganhua Ju Flos Chrysanthemi Indici (Chrysanthemum), Manjingzi Fructus Viticis Negundo (Viticis Fructus) (each 0.5 liang).
Usage: Grind into fine powder. Use rice paste boiled in wine to form pills the size of wutong seeds. Take 70 pills per dose on an empty stomach, washed down with salted water.
Note: All the aforementioned prescriptions consist of warm, mineral, and heavy-settling medications. Although they can tonify Yang deficiency in the Lower Jiao, mineral substances are heavy and require proper calcination/fire processing to become effective. When combined with drying and hot medications, they often lead to hyperactive floating Yang. Moreover, vertigo often involves Wind or Fire pathogenic factors; users should reflect deeply on this.

Miscellaneous Prescriptions
Benshi Gouteng San (Uncaria Powder from "Essential Abilities"): Treats liver jue (reversal) causing dizziness, clearing the head and eyes.
Ingredients: Gouteng Ramulus Uncariae cum Uncis (Uncaria Vine with Hooks), Chenpi Pericarpium Citri Reticulatae (Tangerine Peel), Banxia Rhizoma Pinelliae Preparatum (Prepared Pinellia), Maimendong Radix Ophiopogonis (Ophiopogon), Fuling Sclerotium Poria (Poria), Fushen Sclerotium Poria cum Radix Pini (Poria with Pine Root), Renshen Radix Ginseng (Ginseng), Ganhua Ju Flos Chrysanthemi Indici (Chrysanthemum), Fangfeng Radix Saposhnikoviae (Saposhnikovia) (each 0.5 liang), Gancao Radix Glycyrrhizae (Licorice) (1 fen), Shigypsum Fibrosum (Gypsum Fibrosum) (1 liang).
Usage: Cut into small pieces. Take 4 qian per dose, decoct with seven slices of fresh ginger.
Note: The previous discussion by Academician Xu is quite accurate, but the rationale behind the medication in this prescription remains unclear.
Respectful Review: The medication in all previous prescriptions for treating dizziness is not precise enough. The explanation in *Zhizhi Fang* regarding Xiangju Yin is particularly contrary to medical principles. Generally, when external pathogens invade, the principle is to release the exterior, treating according to Cold, Wind, Summerheat, or Heat. For internal accumulation of Phlegm-fluids, clearing Phlegm must be prioritized. For Qi deficiency, tonifying Qi is appropriate, as in Dongyuan's methods. For Blood deficiency, nourishing Blood is suitable, such as modifications of Siwu Tang. For Kidney deficiency where Qi does not descend, nourishing Yin and tonifying the Kidney is required. If one rigidly adheres to the aforementioned medications, how can one hit the vital point of the disease?
