Not safe! Toxic, come to think of it medicine is toxic too - theres been studies provng this, recently a study was released showing that migraine medicine cures migraines in the long run - which makes sense because if medicine cured the problem for good you wouldn't rebuy the product!
If you want to look younger, don't put toxins in your body, in fact if you want to be euphoric and not have your social phobia or disorder don't put toxins in your body. I guess it's impossble to not put toxins in your body at the least flush them out with water.
Raw fresh fruits and veggies and water will cure anything and everything. And shit like dairy, wheat, meat ect make it all worse. Obviously its kinda unrealistic to give up all of that but the point is that the less you eat - the better you will look and feel and function and you won't be sick because sickness is just your body flushing out toxins - google it! Google the water cure and raw food diet and see for yourself
