''Gynura bicolor, ''hongfeng cai 紅鳳菜, okinawan spinach or edible gynura, is a member of the chrysanthemum family (Asteraceae). It is native to China, Thailand, and Myanmar but grown in many other places as a vegetable and as a medicinal herb.〔(Flora of China, ''Gynura bicolor'' (Roxburgh ex Willdenow) Candolle, 1838. 红凤菜 hong feng cai )〕 There are two kinds: one that is green on both sides, and another with leaves that are green on the top and purple underneath. Both kinds are considered medicinal vegetables. ''Gynura bicolor'' is a perennial and therefore found for sale throughout the year; however, winter and spring is the best time. ==Uses== ''Gynura bicolor'' is rich in iron and potassium, calcium, vitamin A, etc. According to Chinese food grouping, ''Gynura bicolor'' is a 'cool' food,〔(【引用サイトリンク】 Chinese Kitchen )〕 so the leaves are stir-fried with sesame oil and ginger (both 'hotter' foods) to achieve a balance. The stems and roots of the plant can also be made into tea by boiling with water. Choose leaves with few bruises and without black stains. In Japan, ''Gynura bicolor'' is eaten as local vegetable in Ishikawa, Kumamoto and Okinawa and so on, blanched lightly and served with ponzu, as an ingredient of miso soup, or tempura. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gynura bicolor」の詳細全文を読む スポンサード リンク
