People who “automedicate” can be making a horrible mistake.
Consider that a physician relies on courses in anatomy, physiology, organic chemistry, biochemistry, pathology, immunology, virology, parasitology, and others to get his basic knowledge of the human body and its associate workings, as well as courses in pharmacology to get a knowledge of drugs.
Replacing those basics, as well as years of experience, with a few bits of knowledge gleaned form the internet, or what was told you by your “interlaws” does not make sense. Just as there are good, logical reasons that we get piskei halacha from Rabbanim, we get medical opinions from doctors. While they do not know everything, their knowledge is better than that of those who have not acquired it.
Regarding all the “herbal” remedies mentioned above, a word of caution. Many people feel that these, since they are not “drugs”, need not be approached with caution. This is a misconception. They are not regulated by agencies such as the FDA. This, however, is a legal issue, not a medical one. Just because these substances occur in nature does not mean that they do not pose any dangers. Many natural substances can kill, be addictive, cause uterine contractions or abortions, and have many other side effects.
Be careful, amass information from reliable sources (usually academic)and consult a physician that knows you. If you don’t have one, get one.
