Bulk turmeric powder is the ground, dried rhizome of Curcuma longa, and India grows most of the world supply. Heavy metal testing matters more here than for most spices.
Bulk moringa is the dried leaf of Moringa oleifera, sold as powder or tea bag cut. Origin, certification, and microbiology results are what separate one lot from another.
