Tian Ma Gou Teng Yin (Gastrodia and Uncaria Drink)

Tian Ma Gou Teng Yin is a multi-herb Traditional Chinese Medicine formula, not a single nutritional ingredient, so its profile reflects a composite of bioactive phytochemicals rather than conventional macronutrients/micronutrients. Key bioactive compounds include: Gastrodin (p-hydroxybenzyl alcohol glucoside) from Tian Ma (Gastrodia elata) at approximately 0.25–1.0 mg/mL in standardized decoctions, serving as the primary neuroprotective alkaloid; Rhynchophylline and Isorhynchophylline from Gou Teng (Uncaria rhynchophylla) at approximately 0.1–0.5% dry weight, functioning as calcium channel blockers with antihypertensive properties; Vanillin and parishin derivatives from Gastrodia at trace concentrations (0.01–0.05 mg/mL). Huang Qin (Scutellaria baicalensis) contributes Baicalin at approximately 5–15 mg per gram dry herb and Baicalein, both potent flavonoids with antioxidant capacity. Du Zhong (Eucommia ulmoides) provides chlorogenic acid (~2–4 mg/g) and pinoresinol diglucoside (~1–3 mg/g) supporting vascular tone. Yi Mu Cao (Leonurus japonicus) contributes leonurine alkaloids (~0.1–0.3 mg/g) with uterine and circulatory activity. Niu Xi (Achyranthes bidentata) provides beta-ecdysterone (~0.1–0.5 mg/g) and saponins. Shen Jing (Loranthus) contributes quercetin and rutin (~1–3 mg/g combined). The formula contains negligible macronutrients (protein <0.5 g per standard dose, carbohydrates 2–5 g per decoction primarily from polysaccharides, fats <0.1 g). Mineral content includes trace calcium (~10–20 mg per dose), potassium (~50–80 mg per dose), and magnesium (~5–10 mg per dose). Bioavailability note: Gastrodin has relatively high oral bioavailability (~80–90% absorption in studies), while flavonoids like baicalin undergo gut microbiota-mediated conversion to baicalein for absorption (~20–40% bioavailability). Alkaloids from Uncaria show moderate bioavailability (~30–50%), enhanced by the synergistic decoction process. Total polyphenol content per standard 200 mL decoction is estimated at 50–150 mg gallic acid equivalents.
