Dried Lotus Plumule (Tâm Sen) – 100 g Listed

Product overview: Botanical material cataloged as dried lotus plumule, called tâm sen, trà tâm sen, or lian zi xin, with an advertised package weight of 100 g. This is the green inner embryonic portion of a lotus seed, not the entire edible lotus seed, lotus leaf, petal, flower or a lotus planting seed packet. Actual species, quantity, purification, food-grade labeling, drying method, ingredient purity, contaminants and current batch alkaloid composition have not been independently verified against a physical package.

What Is Lotus Plumule?

Royal Botanic Gardens Kew's Medicinal Plant Names Services recognizes lian zi xin and Nelumbinis Plumula as the traditional ingredient derived from the young cotyledons and embryonic root of ripe Nelumbo nucifera seeds. The Chinese Pharmacopoeia describes the dried inner plumule separately from a whole lotus seed. This identity matters: products sold as lotus seeds, seed hearts, whole lotus embryos or lotus root are not automatically the same plant part.

Lotus plumule is typically described as bitter, rather than a universally mild, sweet tea. Flavor changes with cultivar, processing, quantity and storage; no sensory test for the current retail lot was provided.

Important: Alkaloids and Product-Specific Safety

Lotus plumule can contain biologically active alkaloids, including higenamine in some prepared extracts and products. A published human study involving six participants investigated a particular lotus plumule material and found higenamine in urine above the World Anti-Doping Agency reporting threshold after repeated intake under study conditions. That does not prove the exact amount of higenamine in this retailer's batch, does not establish a safe drinking dose and does not mean every lotus seed product behaves the same way. Athletes who are subject to anti-doping tests should be especially cautious about lotus plumule-containing materials.

Other lotus alkaloids and experimental observations cannot be used to promise that this dried product lowers blood pressure, treats insomnia, prevents a disease or provides a reliably measured clinical benefit. Because the complete alkaloid profile, possible medication interactions and current batch quality are unverified, people who take medicines, are pregnant or breastfeeding, have heart conditions or are considering frequent consumption should consult a qualified professional and inspect verified food-use labeling first.

Buyer Facts

Preparation and Storage Boundaries

The former description suggested one teaspoon per cup of hot water for five to ten minutes. This was a general brewing suggestion, not a tested, lot-specific safety or clinical dosage. The current description does not specify a safe portion size or regular consumption schedule for an unverified botanical lot. Follow an authentic food-grade manufacturer label and seek relevant professional advice when appropriate.

Store the botanical material sealed, dry and protected from heat, humidity and light. Discard any product showing signs of water damage, mold or unusual odors. A current label and dated lot records are needed to establish an expiration period.

Frequently Asked Questions

Is lotus plumule the same as a whole lotus seed?

No. Lotus plumule is the inner embryonic part removed from mature lotus seeds. Whole lotus seeds contain other seed structures and are distinct culinary items.

Is this tea proven to help sleep or lower blood pressure?

No human clinical benefit for this specific product is established by the current materials. Traditional-use descriptions and laboratory experiments do not substitute for a verified human treatment claim.

Does lotus plumule contain higenamine?

Research found higenamine in particular lotus plumule preparations and detected it after intake in a small human study. Concentration in this exact retail package has not been tested. Athletes with testing obligations should avoid treating unverified lotus plumule as a safe supplement without appropriate specialist guidance.

How many cups can I make from 100 g?

There is no verified serving or cup-yield claim. Weight does not establish appropriate dosing or ingredient quality.

Is this a caffeine-free product?

Lotus plumule is not the conventional tea plant, but an additive-free and caffeine-free claim for the actual packaged retail product requires a verified ingredient statement and quality controls.
