This is the method currently used by Jinzhong Baizhebei Essential Oil Studio. The equipment is simple and cheap, and individuals can operate it at home, but the extraction rate is low, the purity is not high, the taste is pungent, and many effective components cannot be extracted. The price of essential oil extracted by this method will also be lower.

And because no organic solvent is used in the whole process, there is no residual solvent substance in the extract, which avoids the existence of harmful substances to human body and environmental pollution in the extraction process and ensures the pure nature of 100%.
