Current patent laws prohibit companies from patenting any substance that is naturally found on the earth or in our bodies. So by deduction all patented drugs since not found on this earth are extraterrestrials. I am of the belief that we have everything on this earth to treat disease. For example, numerous studies dating back to the early 70’s, have shown that the element rubidium is 60-70% successful in treating depression. I have also found that specific amino acids and vitamins can cure depression. The only reason these therapies not used as a first line treatment for depression is there are no pharmaceutical companies extolling their virtue to medical students or drug reps promoting them to physicians. So the everyday consumer is left with using extraterrestrial medicines.
