The syndrome of Cold Strike (Zhong Han) manifests as stiffness and rigidity of the body, lockjaw with inability to speak, or trembling and shaking of the four limbs, or a sensation of chilliness (Sascha Ehan), or a slight fever (Xixi Fare), or sudden vertigo accompanied by absence of sweating. This is caused by the direct invasion of Cold Toxin (Handu). How does it differ from Cold Damage (Shanghan)? It is said: In Cold Damage, there is fever, whereas in Cold Strike, there is no fever. Zhang Zhongjing elaborated extensively on Cold Damage, but did not address Cold Strike because it does not transform into heat. Why? Yang moves and Yin is still; movement generates change, while stillness remains unchanged. Although Cold is a Yin pathogen, once it stagnates and transforms into heat, it follows the movement of Yang and undergoes various transmissions without a fixed pattern. Therefore, the diseases resulting from its transmission must be detailed. However, when it does not transform into heat, the pathogen strikes within the Yin forms, remaining fixed and unchanging. Since it does not change, it stays at the site of the strike and causes illness locally; thus, it is briefly mentioned rather than detailed. Treatment should first employ Suhe Xiang Wan (Styrax Pill) mixed with wine. For mild cases, Wu Ji San (Five Accumulations Powder) is used with one qian of Xiangfu (Cyperus Rhizome) and a small amount of Shexiang (Musk). For severe cases, Jiang Fu Tang (Ginger and Aconite Decoction) is used. If the patient gradually regains consciousness, the body warms up, and speech becomes slightly possible, one must inquire about other symptoms. If the pulse is slow and tight, indicating Qi stagnation with a surging quality, and there are stabbing pains, Fuzi Lizhong Tang (Aconite Decoction for Regulating the Middle) is used with half a qian of Muxiang (Costus Root). If Wind is involved with a floating pulse, causing vertigo and numbness, Fangfeng (Saposhnikovia Root) is added. If Dampness is involved with a soggy pulse, causing swelling, fullness, and pain, Baizhu (Atractylodes Macrocephala Rhizome) is added. If tendons and vessels are pulled and tense, Mugua (Chaenomeles Fruit) is added. If limb joints are painful, Gui (Cinnamon Twig) is added. Acupuncture or moxibustion at the Dantian acupoint is also recommended, preferably with multiple applications. Generally, if Cold strikes the skin, it is superficial; if it strikes the muscles, it feels heavy and burdensome, leading to fluid accumulation and splitting pain, which may occur in the limbs, chest and hypochondrium, shins and back, or lower abdomen radiating to the testicles. If it enters the membrane source between organs, it causes heart and abdominal pain. If it connects to the Zang-Fu organs, it causes severe pain leading to unconsciousness. If it strikes sinews and bones, it causes tendon spasms and bone pain with difficulty in flexion and extension. The treatment of Cold entering the Six Fu and Five Zang organs is described in Zhang Zhongjing's *Jingui Yaolue* (Essential Prescriptions of the Golden Cabinet). Thus, Lung Cold Strike results in expectoration of turbid mucus. Liver Cold Strike results in inability to raise both arms, dryness at the root of the tongue, frequent sighing, chest pain preventing turning over, vomiting, and sweating. Heart Cold Strike causes a sensation of burning like eating garlic in the heart region; severe cases involve heart pain radiating to the back and back pain radiating to the heart, resembling insect biting. If the pulse is floating, spontaneous vomiting leads to recovery. The text lacks information on Spleen and Kidney Cold Strike. However, "Zang Strike" refers to Cold striking the boundaries within which the Zang organs reside, blocking meridians and preventing Zang Qi from entering and exiting, causing disease. True direct strike on the Zang organs would be fatal. *Yonglei Qianfang* states: Liver Cold Strike presents with a tight and wiry pulse at the Yingchong point and left Guan position, with symptoms of chills, fever, red face, apparent sweating, chest irritability, hypochondriac spasm and urgency, and inability to extend the legs. Heart Cold Strike presents with a tight and surging pulse at the Yingchong point and left Cun position, with symptoms like the pungency of leeks, severe heart pain pulling to the back, chills, cold extremities, spontaneous vomiting, and coma. Spleen Cold Strike presents with a tight and deep pulse at the Yingchong point and right Guan position, with symptoms of abdominal distension and fullness, limb spasms, inability to belch, failure of Zang Qi transmission, constipation or diarrhea. Lung Cold Strike presents with a tight and choppy pulse at the Yingchong point and right Cun position, with symptoms of easy expectoration of turbid matter, shortness of breath unable to complete inhalation, chilliness, and coughing upon inhalation. Kidney Cold Strike presents with a tight and slippery pulse at the Yingchong point and left Chi position, with symptoms of dark complexion, weak Qi, shortness of breath, deafness, lower back pain, cramping pain below the knees, and unconsciousness. Treatment requires assessing severity. Severe cases use Jiang Fu Tang as the main formula; mild cases use Buhuanjin Zhengqi San (Non-Exchanging Golden Upright Qi Powder) with Fuzi, or Fuzi Wuji San. For umbilical and abdominal pain with cold extremities, Fuzi Lizhong Tang and Jiang Fu Tang are used. If Cold enters the Liver, add Mugua; if it enters the Lung, add Sangbaipi (Mulberry Root Bark); if it enters the Spleen, add Baizhu; if it enters the Heart, add Fuling (Poria).
