How do you prepare anaesthesia from the substances we get at home?

Answer 1

You don't, quite simply. If you're asking, then you're not qualified to prepare substances that cause anesthesia. Furthermore, anesthesia should only be employed for medical purposes, in which case medical help should be sought. The only anesthesia a person can try at home would be local anesthesia, which results in the loss of sensation in a specific location on the body. This can be done simply with the application of ice to alleviate pain.
