Himekawa Yakuishi
It is a type of igneous rock mined in Itoigawa City, Niigata Prefecture. It has been used for centuries in Chinese medicine as "tiger stone" for medicinal purposes. It is believed to boost the immune system, and locals say it is good to hug a Himekawa Yagishi when you are not feeling well.
The stone contains trace amounts of radioactive elements such as radium and thorium, and also produces radioactive rare gases such as radon and thoron.
Hormesis (an adaptive response that creates resistance to certain substances) is expected to improve the immune system.
