Aloe vera powder comes from the inner leaf gel. First the gel is dehydrated, then ground into a fine powder that keeps on the shelf. Most of the latex and aloin get removed during processing. That leaves a product milder than whole-leaf or juice forms.
People use the powder to ease occasional stomach discomfort and keep skin hydrated. Some choose it because the powder is concentrated, without extra additives. Mix it into water or a smoothie.
Stir the powder into liquid once or twice daily, often before meals. Because the powder is concentrated, start with a small amount to gauge your tolerance.
Pay attention to a few cautions. The powder might lower blood sugar, so use care if you take diabetes medication. Avoid it during pregnancy and breastfeeding since effects on uterine activity are unclear. Stop taking it two weeks before surgery. Allergic reactions or mild stomach upset can happen at high doses.
