Wild wormwood is edible, but it is crucial to recognize it during the collection process, and also to prevent whether it has been beaten with insecticides on it, so extra care should be taken during the collection process. Patients are not recommended to collect if they do not know whether the land has been pesticided or not. It is better to consume some domestic wormwood, which is safe, so as not to cause poisoning by accidental ingestion of pesticide-beaten wormwood. Wormwood has a strong odor, especially wild wormwood, which can be used to smoke and cure some mosquitoes and flies, and at the same time, home wormwood is safer to consume. The difference in taste between home wormwood and wild wormwood is not much, so there is no need to consume wild wormwood, but home cultivated wormwood can also achieve the function of taste regulation and consumption.
