In addition to the authentic wisteria scintila, another variety of SCintila scintila was found in some areas of Fujian, Hunan, Sichuan, Guangdong, Guangxi and Yunnan in the south of Latitude 27.30 in China through field research. The similarities and differences of two kinds of treophyllum are elaborated.
In jiangxi and Zhejiang mountainous areas north of latitude 27.30 degrees, the epidermis color of the vine near the root at mature stage is purplish brown (referred to as brown wisteria sanyeqing), which is an authentic variety. The surface color of the vine of another species is bluish-white (abbreviated as bluish-white vine). The growth area of the two is distinct, not mixed growth. But they have the same way of reproduction and growth habit. The leaves and fruits have roughly the same appearance. Their differences are as follows: in addition to the different color of the epidermis of the vine, the green leaves of the three leaves of the vine are larger, the vine is thicker, the tuber individual is larger (the largest can reach 400 g/grain), the meat is yellowish and slightly bitter, and there is a fibrous tendon running through the center of the root. Tuber root surface has many emulsion protuberant, show gourd shape rarely. The distribution area of Green vine three leaves is wider, the growth is vigorous, the yield is higher, the number is more.
The two kinds of tubers were found to be different in composition and medicinal effect, so they should not be confused. Through clinical application comparison, qingteng Sanye Green tuber cold, the medicinal effect is not as good as Wisteria sanye green, the dosage of toxic side effects. Authentic wisteria trifoliate green tubers are rare, expensive, medicinal and extremely precious. At present, the three leaf green decoction pieces and preparations sold in the market are the root tuber of Green Vine. Large cargo of three - leaf green is often soil reuteria root posing as.
