My kitchen includes a bunch of chemicals that aren’t kept under the sink or handled only with gloves, including sodium bicarbonate, acetic acid, potassium bitartrate, lecithin, pectin, and ascorbic acid.

I have found bitartrate of potassium the most grateful and efficient saline for depurative action.
