Collection and processing technology of Bufo bufonis

Abstract: the collection and processing technology of toad venom: toad venom is made from the secretions of retroauricular glands and skin glands of amphibians and reptiles of Bufonidae. It is a traditional Chinese medicine. Toad venom contains steroids, alkaloids and other bioactive substances with detoxification, analgesia, opening, anti-tumor and other functions, so it is widely used.

Bufonis is a traditional Chinese medicine made from the secretions of retroauricular glands and skin glands of amphibians and reptiles of the family Bufonidae. Toad venom contains steroids, alkaloids and other bioactive substances with detoxification, analgesia, opening, anti-tumor and other functions, so it is widely used.

Collection technology of Bufo bufonis

Summer and autumn, especially June and July, are the best time to collect toad buf. the captured or domesticated green and adult toads are washed from the soil, dried, fed to spicy foods such as garlic and peppers, or tapped on the head with small sticks to stimulate it to secrete more serous. Then use metal clip or bamboo clip and horn scraper to squeeze and scrape the large warts (retroauricular glands) near the ear roots on both sides of the head and the large and small warts (skin glands) on the back to get their serous fluid and put them into a non-iron container. When scraping, the manipulation should be moderate, if the force is too small, the output will be low, and if the force is too large, it will be mixed with blood or flesh crumbs and the quality is poor. If impurities are mixed, stainless steel tweezers should be used to remove them in time. In the whole process of collection, attention should be paid to the following two points: first, the slurry should not touch the iron ware, otherwise iron oxide will pollute the toad venom and change its color, affecting its medicinal value and taking effect; second, special care should be taken when scraping the slurry, not to let it splash into the eyes, otherwise the eyes will be poisoned and swollen. If the slurry is mistakenly put into the eye, you should immediately rinse and detoxify it with Zicao juice, and then rinse off with clean water.

Processing technology of Bufo bufonis

First, the pure slurry is removed by 100-120 mesh copper sieve or nylon sieve, and then the filtrate is further mixed evenly, and then the filtrate is poured into the prepared model container to dry into a mass or chess piece crisp, or evenly coated on the flat glass to dry into a piece of crisp. If the environment is dark and humid, it should be dried in time at about 60 ℃, otherwise the fermentation will deteriorate and be scrapped.
