📋 Quick facts

Description: ASPALATHUS LINEARIS EXTRACT — antioxidant (Rooibos).

All Functions: antioxidant (Rooibos)

Quick Facts:

• Category: active

Proven Benefits At A Glance:

• Aspalathus linearis (rooibos) extract contains a compound called eriodictyol-6-C-β-D-glucoside (E6CG)
• E6CG activates muscarinic M3 receptors, which are involved in gland secretion
• Research shows E6CG reaches salivary glands, tear-producing glands, and sweat glands
• Studies in mice and humans suggest potential to address systemic dryness

🔬 The Science

Aspalathus linearis extract, commonly known as rooibos, has been studied for its potential role in addressing systemic dry syndrome—a condition affecting the body’s ability to maintain adequate moisture in various tissues and glands, which impacts quality of life (J Chromatogr B Analyt Technol Biomed Life Sci, 2020). #1: The extract works by activating muscarinic M3 receptors, which are cellular switches that trigger secretory functions in exocrine glands—these are glands that release fluids like saliva, tears, and sweat (J Chromatogr B Analyt Technol Biomed Life Sci, 2020). #2: The active compound responsible for this effect is eriodictyol-6-C-β-D-glucoside (E6CG), a naturally occurring molecule within rooibos extract.

When mice were given rooibos extract, E6CG was detected in their bloodstream, reaching peak levels approximately 19 minutes after administration, and was found to accumulate in key moisture-producing glands including the submandibular and sublingual glands (which produce saliva), parotid glands (also salivary), lacrimal glands (which produce tears), and sweat glands in palm skin (J Chromatogr B Analyt Technol Biomed Life Sci, 2020). #3: The research indicates potential for rooibos extract to function as a food ingredient for improving systemic dryness, though the sources provided are limited to this single study examining pharmacokinetics and gland distribution (J Chromatogr B Analyt Technol Biomed Life Sci, 2020).
