Which herb has laxative action and cardioprotective effects and contains alpha-linolenic acid, lignans, and mucilage?

• A. Medicago sativa (Alfalfa)
• B. Mentha piperita (Peppermint)
• C. Linum usitatissimum (Flaxseed)
• D. Matricaria chamomilla (Chamomile)

Answer: (C)

Flaxseed stands out because it provides a blend of soluble mucilage, omega-3 fatty acids, and lignans. The mucilage swells in the gut, binds water, and adds bulk to the stool, producing a gentle laxative effect that helps with regularity. At the same time, flaxseed supplies alpha-linolenic acid, an omega-3 fatty acid that supports cardiovascular health by reducing inflammation and triglycerides. The lignans in flaxseed act as phytoestrogens with antioxidant activity, contributing further to heart protection by improving lipid oxidation and vascular health. The other herbs listed don’t combine these three features, so flaxseed best matches the description.
