One of the reasons Okinawa is justly famed for longevity has to do with the natural healing power of plants. In an extraordinarily beautiful location overlooking the Pacific Ocean, there is a large-ish garden dedicated to growing native healing plants. It's an added attraction to the popular Kurukuma Restaurant in Tsukishiro City, and I spent a refreshing hour strolling through the grounds in the rain the other day. (It's mid-rainy season now in Okinawa.)
When I called the plants grown there herbs, I was duly corrected. The right word is 'yaku-soh'." (literally, medicine-grasses) Herbs are mainly for adding taste and fragrance to food. Okinawan healing plants are linked to specific medical effects, such as lowering blood pressure. However, just like herbs, they are often added to whatever's cooking or made into tea.
Hibiscus tea for beautiful skin. Mulberry tea to cure a cold. Ukon tea for the liver. That sort of thing.
Surely Okinawa isn't the only place where natural healing plants grow. However, it may be one of the few places where the medicinal uses of leaves, flowers, stems and roots are common knowledge and hold a valued place in daily life.
The environment is so generous, if only we would respect it more and take better care of it. As my niece likes to say: "Save the Earth, it's the only planet with chocolate." Kidding aside, chocolate comes from cacao, and cacao is also a traditional healing plant.
