Identification of true and false Ferula
Ferula ferula, also known as Wei Qujia and Cai Wuwei, is the resin of Ferula ferula, Ferula Sinkiang and Ferula Fukang, mainly produced in Central Asia, Iran, Afghanistan and other countries and regions, and also produced in Xinjiang, China, mainly growing in Gobi desert, barren hills and other sandy land. Most of them were harvested before their trees blossomed. First loosen the soil, expose the roots, and cut the stems from the roots, that is, the emulsion flows out from the cross section and covers the leaves. After about 10 days, the exudate solidifies into fat, and then it can be scraped off, dried in the shade, sealed and insulated. It is warm in nature, bitter and pungent in taste, and has the effects of promoting digestion, eliminating stagnation and killing insects. It is often used to treat abdominal mass, insect accumulation, meat accumulation, chills and pains, malaria, dysentery and other diseases. There are counterfeit products processed and imitated from the bulbs of Allium plants in the market, posing as authentic Ferula, so attention should be paid to identification when using them.
The authentic Ferula Ferula is mostly concentrated from small pills into blocks of different sizes. The appearance is dark yellow or dark brown, and it will turn red-brown after long storage. The newly collected Ferula Ferula is called "colorful Ferula Ferula" because its cross section is milky white or yellowish brown, or reddish brown staggered. Quality such as grease, hardness such as ash; Adding water and grinding to form white emulsion; Because it contains nearly 20% volatile oil, it has a strong and lasting smell similar to garlic, so it is also called "Ferula", which tastes bitter and spicy, like garlic.
The appearance of the processed fake is irregular block or granular, the surface is yellow-brown or brown, with a little luster, and the cross section does not have the characteristics of genuine products; Hand-polished, loose and fragile; There is no special smell of genuine garlic, only onion and garlic, but it is not strong.
Modern pharmacological research shows that the unique smell of Ferula can be absorbed from the intestine and can be used as enema to drive away wind. Its decoction has inhibitory effect on Mycobacterium tuberculosis and can be used as stimulating expectorant, but the processed fake medicine does not have these effects, and misuse will delay treatment, so it should be carefully distinguished.
