Cream of Tartar helps against constipation. Taking a small amount, about a third or a half teaspoon together with a small amount, about a half teaspoon of Milk of Magnesia, might be enough to help. Since taking magnesium as a laxative regularly, will eventually stop working and even make the original problem worse, it is recommended that the Milk of Magnesia should only be used not more than around once a week. Whether the same applies to Cream of Tartar is not known.
In any case, taking even a teaspoon of Cream of Tartar every day seems to cause weight gain for some people. And taking large amounts can cause heart issues. This is because of Cream of Tartar's high potassium content. (It is reported that someone who took several tablespoons to help constipation ended up in the hospital.)

In the above mentioned link, Cream of Tartar is also mentioned as being used in a suppository combined with Bicarbonate of Soda and polyethylene glycol.
