Sankhapushpi (Convolvulus pluricaulis) is an Ayurvedic herb containing shankhpushpine alkaloids that may support memory and cognitive function. The plant's bioactive compounds appear to modulate neurotransmitter activity in the brain, though clinical evidence remains limited.
Sankhapushpi (Convolvulus pluricaulis Choisy) is a perennial herb from the Convolvulaceae family, native to India and growing as a prostrate or ascending plant with hairy stems and leaves. The herb is sourced from both wild and cultivated plants primarily in tropical regions of India, with extraction typically using ethanol or water to obtain phytochemicals including alkaloids and flavonoids.
The research dossier reveals no human clinical trials, randomized controlled trials, or meta-analyses have been conducted on Convolvulus pluricaulis. All available evidence comes from phytochemical analyses, traditional use documentation, and indirect references to in vitro or animal studies without specific human clinical data or PubMed citations.
No clinically studied dosage ranges are available for Sankhapushpi in any form (extract, powder, or standardized preparations). The research provides no information on standardization percentages or recommended doses. Consult a healthcare provider before starting any new supplement.
Sankhapushpi (Convolvulus pluricaulis) is not consumed as a food for macronutrient value; it is used as a medicinal herb, typically as whole-plant powder, decoction, or extract. Its therapeutic relevance lies in its bioactive phytochemical profile rather than caloric or macronutrient content. **Bioactive compounds (approximate concentrations based on phytochemical analyses of whole dried plant):** • **Flavonoids:** Kaempferol (~0.02–0.05% dry weight), quercetin glycosides (trace amounts) — contribute to reported antioxidant and neuroprotective activity; bioavailability of flavonoids generally low (5–10%) without lipid co-administration. • **Alkaloids:** Shankhapushpine (a major alkaloid, ~0.03–0.1% dry weight), convolvine, convolamine — believed to be primary neuroactive constituents; oral bioavailability data not established in human pharmacokinetic studies. • **Triterpenoids/Steroids:** β-sitosterol (~0.01–0.03%), shankhapushpine-related coumarins — β-sitosterol has poor oral bioavailability (~5%) but may contribute to anti-inflammatory effects. • **Glycosides:** Scopoletin (a coumarin, ~0.005–0.02%), ayapanin — scopoletin has moderate oral absorption. • **Volatile oils:** Trace amounts of essential oils (composition not fully characterized). • **Phenolic acids:** Chlorogenic acid, caffeic acid (trace to low concentrations); moderate bioavailability. • **Carbohydrates/Mucilage:** Contains polysaccharide mucilage (~5–8% of dry weight), which may act as a prebiotic fiber and influence gut-mediated absorption of other compounds. • **Crude protein:** ~8–12% of dry weight (not a significant dietary source). • **Crude fiber:** ~15–20% of dry weight. • **Minerals (per 100 g dry herb, approximate):** Calcium (~200–400 mg), Iron (~5–15 mg), Zinc (~2–5 mg), Magnesium (~100–250 mg), Potassium (~500–900 mg) — mineral bioavailability may be reduced by fiber and tannin content. • **Vitamins:** No significant vitamin content documented; trace amounts of ascorbic acid (~2–5 mg/100 g dry weight) reported in some analyses. • **Tannins:** ~2–4% dry weight — may reduce protein and mineral bioavailability and contribute to astringent taste. **Typical dosage form concentrations:** Traditional Ayurvedic dose is 3–6 g of whole plant powder or 10–20 mL of fresh juice (swarasa) daily. Standardized commercial extracts may concentrate alkaloid and flavonoid fractions to 2–5× the whole-plant levels. **Bioavailability notes:** Most bioactive alkaloids and flavonoids have limited published pharmacokinetic data in humans. Traditional preparation methods (decoction with ghee or milk, known as 'ksheerapaka') likely enhance lipophilic compound absorption. The presence of mucilage may slow gastric emptying and modulate release kinetics of active constituents.
Shankhpushpine and other alkaloids in Sankhapushpi may enhance acetylcholine activity and support GABA neurotransmitter function. The herb's flavonoids and phenolic compounds appear to provide neuroprotective effects by reducing oxidative stress in neural tissue. These mechanisms potentially support memory formation and cognitive processing pathways.
Current clinical evidence for Sankhapushpi is extremely limited, with most research consisting of traditional usage documentation rather than controlled trials. A few small animal studies have suggested memory-enhancing effects, but no significant human clinical trials have been published. The evidence base relies primarily on centuries of Ayurvedic traditional use rather than modern scientific validation. More rigorous human studies are needed to confirm therapeutic effects and establish safe dosing protocols.
Sankhapushpi is generally considered safe in traditional Ayurvedic doses, but comprehensive safety data is lacking. Potential interactions with sedative medications or cognitive enhancers have not been studied clinically. Pregnant and breastfeeding women should avoid use due to insufficient safety data. Individuals taking prescription medications for neurological conditions should consult healthcare providers before use.
