Cuscuta Cuscuta is spherical, with a diameter of 1 ~ 1.5 mm and a grayish brown or yellowish brown surface. Observing under a magnifying glass, there are tiny bumps on the surface and a concave linear hilum at one end. Solid texture, not easy to be crushed by nails, sticky and slippery when wet with water, easy to break when boiled in boiling water, revealing yellow to brown curly embryos, like spinning yarn. Slight breath and light taste.
The easiest way is to try dodder, which is slightly salty.
Cuscuta chinensis contains a large proportion of impurities, which are very common, and some of them are artificially adulterated. In order to increase the weight, cement particles, sand grains, clods, etc. Similar in appearance, size and color, mixed with dodder to illegally obtain economic benefits. Cuscuta Cuscuta is spherical or ovoid with a diameter of about one millimeter. Very small, it is difficult to recognize with the naked eye. Some grass-roots hospitals and pharmacies are limited by objective conditions, so it is difficult to identify adulterated dodder. Bian Xiao suggested that the following simple identification methods can be adopted during acceptance:
1, color identification: pure dodder is taupe or yellowish brown with smooth surface; The adulterated surface is earthy and dull.
2, twisting method: take a small amount of dodder in the palm, twist with the other thumb. Cuscuta chinensis is firm and not easy to break; If there is dirt in the palm of your hand, it means it is mixed with clods.
3. Soaking method: a small amount of Semen Cuscutae is soaked in a transparent glass container for a period of time to make the water absorption volume of Semen Cuscutae expand; Those mixed with cement grains, sand grains and clods will sink to the bottom of the container, but the cement grains and sand grains will not swell, and the clods will dissolve quickly, making the liquid turbid.
4. Cooking method: take a small amount of dodder and soak it in boiling water, and the surface will be sticky; When heated and boiled until the seed coat breaks, the yellow-white tendril-like embryo is exposed, which seems to be spinning, and it is genuine.
