Common Bean
Phaseolus vulgaris
The common bean was domesticated independently in Mesoamerica and the Andes thousands of years ago, and it became one of the great staple foods of the Americas. Indigenous farmers grew it as one of the Three Sisters, planted alongside corn and squash in a partnership where the bean climbed the cornstalk and fed the soil with nitrogen while the squash shaded the ground below. After the Columbian exchange it traveled to Europe, Africa, and Asia and was folded into cuisines and folk medicine everywhere it landed. In European and Latin American folk herbalism, the dried pods, left over once the beans themselves were shelled, were simmered into a tea traditionally used to support healthy fluid balance and steady blood sugar.

Traditional preparations.
A gentle old-fashioned infusion made from the papery dried pods, once the beans have been shelled out, traditionally sipped to support healthy fluid balance and everyday blood sugar wellness.
Traditionally, a decoction is made by simmering about 2 tablespoons of dried, crumbled bean pods in 500 ml of water for 15 to 20 minutes, then straining and drinking warm, once daily.
A mild, nourishing broth traditionally offered to those recovering from illness or in need of gentle, easily digested sustenance.
Simmer 1/2 cup of dried beans, soaked overnight and rinsed well, in 4 cups of fresh water until very soft, about 1 to 2 hours. Strain off the broth and sip it warm.
Safety.
Raw or undercooked beans, especially red kidney beans, contain a natural toxin that can cause severe vomiting and diarrhea. Dried beans must be soaked and then boiled hard for at least 10 minutes before eating or slow cooking; a slow cooker alone doesn't reach a high enough temperature to destroy the toxin. Bean pod preparations used for blood sugar support may interact with diabetes medication or diuretics.
