香港脚病,是因为双脚接触地面,受到寒、暑、风、湿等邪气侵袭,从而形成这种病症。它起初从足部开始,逐渐向上蔓延至小腹,严重时甚至上攻心胸,如果不及时救治,会导致死亡。然而,该病症有干性和湿性之分。湿性香港脚,表现为双脚肿大,或者向下流注生疮,浸淫流水,用鸡鸣散主治。干性香港脚,表现为两小腿不肿,或者麻木僵硬,或者拘挛紧急,或者松弛无力,这是血虚兼夹湿气所致,用四物汤加味主治。如果脚气疼痛,导致关节无法屈伸,用乌头汤主治。如果出现上气喘急,以及小腹感觉迟钝(不知痛痒),恐怕邪气攻心无法救治的,用肾气丸主治。如果是香港脚邪气冲心,用矾石汤浸泡双脚。

Hong Kong foot disease (Jiaoqi) arises from the feet contacting the ground and being invaded by cold, summer-heat, wind, and dampness pathogens. It initially starts in the feet, gradually ascending to the lower abdomen, and in severe cases, attacks the heart and chest. If not treated promptly, it can be fatal. However, this condition is categorized into dry and wet types. In wet Hong Kong foot, both feet are swollen, or sores form with oozing fluid; Ji Ming San (Cockcrow Decoction) is the primary formula. In dry Hong Kong foot, the calves are not swollen but may present with numbness, stiffness, spasms, or flaccidity; this is due to blood deficiency combined with dampness, treated primarily with Si Wu Tang (Four Substances Decoction) modified. For Jiaoqi pain causing inability to flex or extend the joints, Wu Tou Tang (Aconite Decoction) is used. If there is wheezing and shortness of breath, along with insensibility in the lower abdomen, suggesting impending cardiac attack which may be incurable, Shen Qi Wan (Kidney Qi Pill) is indicated. For Hong Kong foot attacking the heart, Fan Shi Tang (Alum Decoction) is used for foot soaking.
