In fact, he clearly explains when you should see a doctor and when you should avoid one because sometimes doing nothing but rest, fluid, and a cool mist humidifier is the best treatment.
For example, I grew up on frequent doses of antibiotics for the strep throat. Practically all winter long I was sick. Regarding treating the strep throat Dr. Mendelsohn writes,” ...although the use of penicillin may shorten the course of the strep throat by three or four days, it may also cause the recurrence of the infection all winter long. Antibiotics, while knocking out the strep bacilli, also prevent the development of antibodies that are the body’s natural defense against disease. If the strep infection is not treated but is allowed to run its course, the body will produce antibodies to fight it that can continue to protect the child against reinfection during the remainder of the winter season.” Considering most colds and sore throats are not as severe as a strep infection, this insight alone is quite important.

As a baby, she had a blocked tear duct and so did her first baby. Her first child was facing possible surgery for it. After many months of massaging the area eventually, the tear duct opened and the toddler avoided surgery. Fortunately a few weeks before the birth of her second child she read Dr. Mendelsohn's book and learned that a blocked tear duct is a side effect of silver nitrate drops put in the eyes of a newborn at birth. These drops are prescribed with the assumption that the mother has gonorrhea and can cause a blocked tear duct in 30 percent of babies. Knowing why this is done, she refused the eye drops for her second baby and he did not develop a blocked tear duct.
