Abstract Thujone is a natural or manmade ketone monoterpenoid, fragment substance which is most famous for its use in absinthe spirit. It is found in various plants which are used as medicines, foods, hard drinks, and for various purposes in our daily life. The plants that contain thujone are wormwood, clary, tansy, sage, some junipers, oregano, thuja, cypress, mentha, lavender, etc. So it is likely to use thujone-containing plants for food and medicine can be harmful to our body. It has been reported that long-term use of these plants may leads to diseases like stomach aches, seizures, renal failure, hallucination, rhabdomyolysis, paralysis and even death. In current review we have discussed different toxic effects of thujone and have tried to search the plausible solutions by which we can minimize or remove the thujone from daily used plant products.
