A total of 147 subjects presenting with common colds were discussed in the context of traditional Japanese medicine. Using diagnoses and treatment based on traditional Japanese medicine, the subjects were divided into three groups, including wind-cold and wind-heat, and were prescribed herbal medicines. The subjects were compared in terms of time-of-onset, complaints, subjective and objective symptoms, and constitution.1) Wind-cold was observed in 42.9% of their cases, mostly treated with kakkonto/keishito. This type of common cold occurred frequently during winter but was less common in summer. Many patients were found to have a weak stomach and/or an excessive sensitivity to cold. Typical symptoms were chills (often the chief complaint) and cold sensations in the limbs, both of which are external cold symptoms. There were no objective symptoms other than a floating pulse. 2) The percentage of wind-heat colds was 46.3%. Gingyosan was frequently used. This type of common cold occurred more frequently in spring, but was also seen in autumn. Slightly more subjects were sensitive to heat and/or had a healthy constitution. Symptoms were extensive, including external/internal heat symptoms, such as pharyngeal pain (often the chief complaint), redness of the pharynx, hot sensation, feverishness, dry mouth favoring cold water, and dryness symptoms and, less often, cold state symptoms. 3) The remaining subjects, accounting for 10.9%, were regarded as a complex of cold and heat states, and were treated with kufugedokuto.
