The words right are not those of a religious zealot. Neither are they transcribed from a holy book. They are, in fact, the Dr’s prescribed cure for zits.

On pimples and blackheads: "To promote cure, all bad habits must be stopped. Tobacco in all forms must be given up. All stimulants, such as beer, wine, and spirits must be avoided. Drugs (especially arsenic) must be shunned, even though they are called "blood purifiers". Good habits must be learnt. Meals must be limited to three a day; pig in any form must never be eaten, meat must only be taken once a day, or even every other day, and then not fat."
