The Effects of Ryo-kei-jutsu-kan-to / 日本東洋医学雑誌

ABSTRACT

There are many indications for Ryo-kei-jutsu-kan-to, such as orthostatic hypotension, cardiac neurosis, migraine, congestive heart failure, benign paroxysmal positional vertigo and eye disease. Although in oriental medicine Ryo-kei-jutsu-kan-to is used as a hydragogue agent for sui-doku (disorders of the body's fluid metabolism), its actual effect on hydragogue action remains unclear. We previously carried out hemodynamics tests before and after administration of Ryo-kei-jutsu-kan-to for a patient with orthostatic hypotension due to peripheral autonomic disorder. The pathosis of the patient before administration of Ryo-kei-jutsu-kan-to was found to be sui-doku caused by the excessive increase of circulating blood volume. We reported that after administration of Ryo-kei-jutsu-kan-to the blood pressure of the patient in the standing position was elevated by increased peripheral vascular resistance, while excessively increased circulating blood volume decreased. This time we administered Ryo-kei-jutsu-kan-to for four cases, such as orthostatic hypotension with migraine, cardiac neurosis, congestive heart failure, and hypotension in dialysis. We again realized that it also increases peripheral vascular resistance. As one of the dimensions of so-called hydragogue action, it is important to understand that Ryo-kei-jutsu-kan-to has a hydragogue effect against the retention of excess fluids (sui-doku) in the body through increasing peripheral vascular resistance by vasoconstriction.
