Tokito is used to treat patients with an asthenic, cold constitution, who have symptoms of chronic pleuritic pain, epigastralgia, and backache. There is no previous report on treatment of pruritus cutaneus with tokito. However, here we report a case of combined cutaneus pruritus and coldness, successfully treated with tokito. Our patient was a 38-year-old female, who reported having had facial pruritus cutaneus for one year. She attended our clinic in May of the year, because she had taken a turn for the worse. She was sensitive to cold, had poor circulation, felt cold in the abdomen, and reported that sleeping was difficult due to a cold back. We prescribed tokito (5.0 g/day). Her symptoms improved within six days. However, her symptoms, especially cold abdomen and cold back, returned when she drank cold water or stopped taking tokito. She was quite informative in that she prepared detailed records of her symptoms on visiting our clinic.
Tokito contains herbal medicines common to daikenchuto and tokikenchuto and hangekobokuto. Therefore, tokito could be a suitable herbal medicine for patients with pruritus cutaneus caused by coldness and qi stagnation and spleen deficiency.
