Traditional Japanese Kampo medicine is a holistic healing system that has been practiced for centuries in Japan. It is rooted in ancient Chinese medicine but has evolved over time to incorporate unique Japanese insights and medicinal plants. One such plant that has played a significant role in Kampo medicine is Houttuynia cordata, commonly known as Houttuynia herb. This article explores the historical uses, properties, and modern rediscovery of Houttuynia herb within the context of Japanese Kampo medicine.
Kampo Medicine: A Brief Overview
Kampo medicine, which translates to "Han Chinese medicine," originated in China but was introduced to Japan over a thousand years ago. It combines traditional Chinese medical principles with indigenous Japanese knowledge and botanical resources. Over time, Kampo medicine has developed its own diagnostic methods and unique herbal formulations.
Kampo medicine is officially recognized and integrated into the Japanese healthcare system, and Kampo herbal remedies are commonly prescribed by medical practitioners alongside conventional Western medicine. This integration allows patients to benefit from both systems, making it a hallmark of Japan's unique approach to healthcare.
