What are the common uses of TCE?

TCE had many uses in the past. It was used as a grain fumigant and pet food additive until its use was banned for food and medical uses in 1977. Until the mid-1970s, it was used to extract vegetable oils and spices and to extract caffeine for the production of decaffeinated coffee. TCE was used for anesthesia in hospitals—especially for women during childbirth during the 1950s and 60s, as a surgical disinfectant, and to treat migraines and trigeminal neuralgia –which is a nerve disorder that causes severe pain in the face.
