Wind is a pathogenic factor belonging to Yang. Cold is a pathogenic factor belonging to Yin. Wind belongs to Yang, and its nature is characterized by movement and change. Cold belongs to Yin, and its nature is characterized by stillness and stability. Therefore, when discussing diseases involving wind, symptoms become unpredictable and difficult to control; when discussing herbs for treating wind, their efficacy varies and becomes indeterminate depending on the specific presentation.
For instance, the Liver (Gan) is associated with wind. If a disease originates from wind, it often manifests through Liver-related signs. However, there are cases where wind does not reside in the Liver but affects the exterior of the muscles. In such cases, presenting with aversion to wind and spontaneous sweating, Guizhi Tang (Cinnamon Twig Decoction) should be used to release the muscle layer. If wind affects the Taiyang Bladder channel, presenting with migratory wind attacking the head, Qianghuo (Notopterygii Rhizoma et Radix) should be used. If the symptom is generalized bone pain, Fangfeng (Saposhnikoviae Radix) should be used. If wind attacks the vertex of the head, Gaoben (Ligustici Rhizoma et Radix) should be used. Such are the situations.
Furthermore, if wind resides in the Shaoyin Kidney channel, presenting with latent wind attacking the head, Duhuo (Angelicae Pubescenti Radix) should be used. If the symptom is dry mouth with thirst, Xixin (Asari Radix) should be used. If wind penetrates into the bone marrow, presenting with phlegm misting the orifices and causing closure, Bingpian (Borneolum Syntheticum) should be used. If wind is between the skin and bone marrow, presenting with convulsions, scabies, and leprosy-like conditions, Baihuashe (Agkistrodon) should be used. If wind is in the joints, presenting with obstruction of all nine orifices, Shexiang (Moschus) should be used. If the symptom is bi-syndrome pain due to wind-dampness, Yinyu (Skimmiae Japonicae Fructus) should be used. If wind is in the meridians, presenting with sores, ulcers, and carbuncles, Shanji (Manis Squama) should be used. If the symptom is congestion of phlegm and saliva, Zaojiao (Gleditsiae Sinensis Fructus Spina) should be used. If wind is in the twelve meridians, presenting with stubborn bi-syndrome and cold pain, Weilingxian (Clematidis Radix) should be used. If wind is in the intestines and stomach, presenting with foul sores and swelling/toxins, Feizao (Soapberry Fruit) should be used. If wind is in the Yangming Stomach channel, presenting with various diseases of the head and face, Baifuzi (Typhonii Rhizoma) and Baizhi (Angelicae Dahuricae Radix) should be used. Such are other situations.
Moreover, if wind-heat is in the Lung, presenting with nasal congestion and rhinorrhea (bi-yuan), Xinyi (Magnoliae Flos) should be used. If the symptom is visual opacity and vertigo, Ganju (Chrysanthemi Indici Flos) should be used. If the symptoms are aversion to cold, fever, anhidrosis, and wheezing, Xingren (Armeniacae Semen Amarum) should be used. If the symptom is carbuncles and sores/toxins, Niubangzi (Arctii Fructus) should be used. If the symptoms are wheezing, coughing, and bodily edema, Qianhu (Peucedani Radix) should be used. Such are other situations.
When wind has already entered the Liver and the symptoms involve dampness, then Qinjiao (Gentianae Macrophyllae Radix) can clear damp-heat in the intestines and stomach while dispersing wind pathogens in the Liver channel; Fuping (Spirodelae Herba) enters the Liver channel to disperse wind and promotes diuresis to remove dampness from the Spleen channel; Haitongpi (Erythrophleumi Cortex) treats various pains due to wind-dampness; Bibi (Dioscoreae Hypoglaucae Rhizoma) treats numbness, pain, and cold; Can'erzi (Xanthii Fructus) treats skin sores, tinea, and generalized bi-syndrome; Bajitian (Morindae Officinalis Radix), Gouji (Cibotii Rhizoma), and Sangjisheng (Taxilli Herba) strengthen bones and sinews. Additionally, combining Ruiru (Polygonati Odorati Rhizoma), Bibi, Yinyu, Baizhi, and Baifuzi allows for the treatment of wind-dampness, which can be inferred analogously.
If wind has entered the Liver and the symptoms involve heat transforming into toxicity, then Quanxie (Scorpio) treats fetal wind convulsions; Gouteng (Uncariae Ramulus cum Uncis) treats fright epilepsy and spasms; Chantui (Bombyx Batryticatus) treats skin urticaria; Bohe (Menthae Haplocalycis Herba) treats throat and dental diseases; Shinanye (Rhododendri Mollis Folium) expels heat and strengthens the kidneys; Juemingzi (Cassiae Semen), Muzei (Equiseti Herba), and Ruiren (Prunus Persica Seed) treat wind-heat visual opacities. Combining Xinyi, Bingpian, and Niubangzi allows for the management of wind-heat, which can be envisioned.
If wind disease is in the Liver and symptoms involve phlegm and qi stagnation, then Nanting (Arisaematis Cum Bile Rhizoma) disperses wind-phlegm in the meridians; Tianma (Gastrodiae Rhizoma) treats Liver qi stagnation and deficient wind; Chuanxiong (Chuanxiong Rhizoma) disperses Liver qi stagnation. Combining these with Shexiang allows for the simultaneous regulation of phlegm and qi, which can be contemplated.
If wind disease is in the Liver and symptoms involve wind-toxin, then Shetui (Boa Constrictor Skin) kills gu-poison and wards off evil; Wugong (Scolopendra) dissipates blood stasis and resolves masses. Combining Shanji, Caowu (Aconiti Radix Lateralis Preparata), Niubangzi, and Feizao allows for the management of wind-toxin, which constitutes the remaining scenarios.
If wind disease is in the Liver and presents with cold-dampness symptoms, then Manjingzi (Viticis Fructus), Jiangcan (Bombyx Batryticatus), Wujiaopi (Acanthopanacis Cortex), and Wu Jian Fu (Aconiti Radix Lateralis Preparata) may be suitable. However, their functions and therapeutic effects differ.
If wind disease is in the Liver and presents with bone atrophy and weakness, then Hugutou (Os Tigris, now substituted) and Hu Jiao (Colla Corii Tigris, now substituted) may be suitable. However, their flavors and actions vary in speed and intensity.
Regarding wind disease in the Liver presenting with dry and hot skin, Jingjie (Schizonepetae Herba) must be used to reach the skin and unblock the blood vessels. If wind disease in the Liver presents with sores, scabies, and red eyes, Jili (Tribuli Fructus) must be used to disperse wind and drive out blood stasis. If wind disease in the Liver presents with damp-heat and dry itching, Wuyi (Terminalia Chebulae Fructus) must be used to drain dampness. All these require careful assessment of symptoms to determine the therapeutic direction. The principles are infinite and changes endless. The profound essence lies in daily contemplation and understanding, which cannot be grasped in haste or urgency.
