Oral Use Safe?

It's a misunderstanding. A castor oil, USP grade can be taken internally. The castor oil packs means a small towel soaked with castor oil with a hot pack is applied to the area of the body that is needed. The castor oil packs is not taken internally, but for other conditions only a small amount can be taken internally, but not at the dose used to cause a diarrhea. Also, certain grades of castor oil is not suitable for taken internally.

Usually U.S.P. grade or B.P. grade can be taken internally. Although I tend to use it in small amounts mostly as an antibiotic properties, rather than as a use as laxative effect.

A more milder remedy for laxatives is what I would prefer, such as milk of magnesia, or my own favorite baking soda and sea salt to resolve constipation.

The reason why I don't like to use as a laxative using castor oil is the amounts taken in my opinion were large, and also during World War II, Mussolini the dictator of Italy used castor oil as a means of torture and there were reported deaths as a result. In my opinion, castor oil is a laxative that is too strong for some people and a milder laxative should be used just to be on the safe side. However, prefer to deal with the cause of constipation rather than the use of laxative, which is more like a first aid, rather than a preventive. A 1/8 teaspoon of baking soda and 1/8 teaspoon of sea salt in 1 glass of water should reduce constipation, although in most cases it won't have cause a major diarrhea. The cause of constipation I have found is that people don't use toilet breaks in the morning and acidosis from eating acid forming foods, such as eating oily foods, meats, fats and sweets. Hence, getting sufficiently alkalized and avoiding those foods would be sufficient preventive against constipation. Nature's remedy is gentle and preventive
