Monomer, a molecule of any of a class of compounds, mostly organic, that can react with other molecules to form very large molecules, or polymers.

A standardized extract is created by "pulling out" (extracting) specific compounds from a plant. Standardized Saw Palmetto Berry Extract, for example, is extracted from the fresh berries of the saw palmetto tree. In many cases, standardized extracts are used in studies on herbs because the active ingredients can be monitored for consistency, whereas natural herb powders will vary.

Grains, legumes and seeds are typical sources of Plant Powder, which are made by removing most of the fat and carbs while isolating the protein components.

Essential oils are concentrated plant extracts that retain the natural smell and flavor, or “essence,” of their source. Essential oils are often used in aromatherapy, a form of alternative medicine that employs plant extracts to support health and well-being.
