Professor Fujiwara Shihshi, Kyoto University School of Medicine, Japan began collecting coral, seagrass and starfish off the coast of Japan a few years ago and studying its effective medicinal substances. After dissolving a soft coral collected near Ishigaki Island in Okinawa, they injected blood into the dog’s artery and expanded the blood vessels.

Change the concentration of this substance to observe its effect and found that when adding one billionth of a gram of the substance per milliliter of Ringer’s solution, the effect can occur with a significant effect by adding one hundred millionth of a gram per milliliter. In addition, it is also characterized by having cerebral vasoconstrictor physiological substances, serotonin, hair
