Catch in winter, when the fat is thickest. After slaughter, take the subcutaneous fat and the fat on the intestinal omentum, put them in a pot and boil them into light yellow fat, and filter off the oil residue.

Improve the quality standard of badger oil. Methods: The appearance characteristics of five batches of badger oil and four other animal oils were compared, and their relative density, refractive index, acid value and peroxide value were determined according to the method in the appendix of China Pharmacopoeia 2005. Results: The relative density of badger oil should be 0.905 ~ 0.908, the refractive index should be 1.460 ~ 1.463, the acid value should not be greater than 4.0 and the peroxide value should not be greater than 0.5. Conclusion: The quality standard of badger oil was improved through research.

Badger seed oil is an oil extracted from badger seed fat. Badger, also known as badger, pig badger, Carnivora, ferret species.

There are powerful dark brown claws on the toes of the front and rear feet, and the front claws are longer than the rear claws. Badger's back has long and thick needle-like hair from beginning to end, which is black, brown and white, so it is called "Sesame Badger".

From the clinical observation, badger oil is effective in treating scalds and burns (healing is fast and scars are not obvious). The analysis shows that badger oil has the function of sterilization. "Obvious scar" means that it can promote cell regeneration.
