Organic Ginkgo Biloba Extract Powder

 A: The extract is standardized to >=24% flavonoid glycosides and >=6% terpene lactones via ethanol/water extraction, providing precise, concentrated bioactive potency for cognitive and circulatory formulations. The leaf powder is air-dried whole leaf, retaining the complete phytochemical matrix with 8-12% natural flavonoids — suited for traditional teas, holistic capsules, and clean-label whole-food products. The extract targets high-potency supplement positioning; the leaf powder targets traditional herbal and whole-food markets.

 A: Standardization means each batch of extract delivers a guaranteed minimum of 24% flavonoid glycosides (quercetin, kaempferol, isorhamnetin) and 6% terpene lactones (ginkgolides A and B + bilobalide) as measured by UV and HPLC respectively. This ensures consistent potency and predictable clinical outcomes across batches — critical for supplement manufacturers and finished-good brands requiring reliable dosing.

 A: Research suggests ginkgo’s ability to support healthy cerebral blood flow may indirectly reduce anxiety symptoms related to poor microcirculation and cognitive overload. Human studies using 120-240 mg standardized extract daily have reported modest reductions in anxiety scores. Ginkgo is not a primary anxiolytic; consult a healthcare provider for clinically diagnosed anxiety.

 A: For a traditional decoction, add 1-2 teaspoons (approximately 2-4 g) of leaf powder to 200 ml of water. Simmer gently for 10 minutes, then strain. The tea has a mild, slightly bitter herbal character. It can be combined with gotu kola, ginseng, or green tea for a traditional adaptogen blend.

 A: For most adults at recommended doses (80-240 mg/day standardized extract), daily use for up to 6 months is generally considered safe based on clinical data. Individuals on blood-thinning medications, those preparing for surgery (discontinue at least 14 days prior), or those with seizure disorders should avoid ginkgo or consult a healthcare professional. Cyclical use (e.g., 3 months on, 1 month off) is a common practice.

 A: Ginkgolic acids are naturally occurring alkylphenols in ginkgo that can cause allergic skin reactions and sensitisation in susceptible individuals. Most pharmacopoeias (Ph. Eur., USP) set limits at <10 ppm. Our product exceeds these standards by controlling ginkgolic acids to <5 ppm, reducing sensitisation risk and supporting clean-label claims.

 A: Yes. Ginkgo biloba is a plant-based leaf extract/powder with no animal-derived ingredients, no gluten-containing grains, and a negligible carbohydrate profile. Terpene lactones and flavonoids are non-caloric phytochemicals. Both formats are fully compatible with vegan, vegetarian, gluten-free, and keto lifestyle positioning.
