Stoopid thought. The list of diseases cured by de-wormers is increasing. I remember when castor oil was used for almost anything. i bet it is a pretty good dewormer as well.
It would be interesting to see a correlation in the use of castor oil.. like castor oil sales vs. increased deseases.
We de-worm almost all domestic pets. Maybe it should be a part of a health conscious procol.
