Wide-body golden leech does not contain hirudin, why is it more expensive than Philippine leech containing hirudin?

Leech wide body has an ID card in the pharmaceutical industry-it belongs to traditional Chinese medicine in China Pharmacopoeia. But because it is not included in the Pharmacopoeia, it is not strictly Chinese medicine. A white household and a black household, even if the black household is better than the white household, the reward cannot be higher than the white household. That's the reason.

Philippine leeches suck blood and contain very high anticoagulant hirudin, but the wide body does not suck blood, so the activity and content of anticoagulant substances in the body are not as good as those in Philippine cattle.

Leeches are not cold-tolerant, only distributed in several provinces in southern China, while Borrelia Borrelia is distributed in China, Central China and even North China.

After the wide-body purchase, it will be sold to pharmaceutical companies, which will make Chinese patent medicines after processing, such as Xiong Zhi capsules (many varieties). Leeches in general ingredients are dried leeches with wide body.
