doctors must show that such unconventional treatment provides
relief and prevention of illness. “The total projected out-of-
pocket expenditure for unconventional therapy plus
supplements(such as diet pills and megavitamins)was 10.3 billion
dollars in 1990. This is comparable to the out-of-pocket
expenditure for all hospital care in the Unite ...

... not yet immune to it. This could lead to the belief of chickenpox being one of the oldest diseases.
