Product overview: Loose dried corn silk, also called râu ngô (Vietnamese), pelo de elote or barba de elote (Spanish) and yu mi xu (Chinese), cataloged as a 100 g pack. Corn silk refers to the long strands from the female flowering portion of maize (Zea mays). This is botanical strand material, not roasted corn kernels, corn husks, an instant drink, a seed packet or a standardized medicinal extract. Actual net weight, current batch ingredients, food-grade handling and species authentication have not been independently verified from a recent physical label or supplier lot.
What Exactly Is Corn Silk?
Purdue University's agronomy reference identifies the silk emerging from corn ears as the functional stigma structure associated with potential kernels. Kew's Medicinal Plant Names Services associates corn silk with Zea mays and describes its style/stigma plant parts in traditional source records. These scientific descriptions help distinguish a real silk strand from other maize plant parts; they do not identify the physical contents of a retail package by themselves.
Different from roasted corn tea: Drinks prepared from roasted whole corn or corn kernels have undergone a roasting process and usually taste differently from an infusion made of dried silks. The current listing does not prove that its strands were roasted, blended with corn kernels or concentrated into an extract. A flavor described as mild or faintly corn-like is a possible sensory impression, not a tested tasting specification for this lot.
Buyer-Facing Product Details
| Catalog material | Dried corn silk strands, marketed from Zea mays |
|---|---|
| Known common names | Corn silk, râu ngô, pelo/barba de elote, yu mi xu, stigma maydis |
| Advertised weight | 100 g; all five existing gallery labels also mention 100 g, but physical package not independently weighed |
| Plant part | Styles/stigmas of maize, rather than kernels, husks or roasted-corn beverage mix |
| Ingredient purity | Prior “no additives,” “caffeine-free” and single-ingredient assurances require a current complete ingredient statement and process evidence |
| Origin | Maize is grown in many countries; an earlier generic description of Asia or the Americas does not establish this batch's country of origin |
| Food-grade checks | No supplier lot results for pesticide residues, microbiology, heavy metals, moisture, packaging date or processing verified here |
| Serving or cup yield | No tested lot-specific dose or number of servings verified. Former 2–4 g per cup and 25–50 cups are not certified directions |
Traditional Use Is Not a Medical Claim
The U.S. FDA's food substances database identifies corn silk (Zea mays styles and stigmas) in the context of use as a flavoring agent or adjuvant. This is a regulatory ingredient entry, not a safety certificate for this specific store inventory and not proof of any therapeutic benefit.
A 2026 systematic review and meta-analysis of preclinical corn-silk experiments reported inconsistent effects in diabetic animal models and significant variation by extraction method and dose. A separate 2026 review notes that direct human evidence remains limited. Neither provides a validated daily serving or a basis to promise lower blood glucose, blood pressure, relief of urinary problems or treatment of kidney disease from this loose herb.
If planning to consume a less familiar botanical infusion, verify the packaged product's food-use label and manufacturer instructions first. People who are pregnant or breastfeeding, using medicines such as diabetes or blood pressure drugs, or managing kidney or cardiac conditions should consult a qualified professional about individual risks. This listing is not medical advice, and an herbal drink should not replace proven care.
Storage and Handling
Store dry botanical material sealed and away from heat, dampness and direct sunlight. Avoid material showing mold, damage or unexpected contamination. Follow an authentic package's current ingredients, brewing and best-before instructions when present. The old page's fixed “2–4 grams per cup” and implied serving yield were removed because this batch has not been independently measured or assessed for consistent servings and food-grade suitability.
Frequently Asked Questions
Is this tea made from corn kernels?
No. The catalog describes corn silk strands from maize rather than roasted corn kernels. The actual contents still need confirmation from the current package.
Is this the same as Stigma maydis or Yu Mi Xu?
Those names are used for corn silk in botanical or traditional-herb contexts. Kew MPNS links the common names to Zea mays styles and stigmas. Name equivalence does not verify the particular harvest and processing of this packet.
Does 100 g make 25–50 cups?
No such yield has been tested or guaranteed for this listing. The prior range was an arithmetic extrapolation from a particular spoon/gram amount, not validated human use instructions for the current dried strands.
Is the material additive-free or tested safe to drink?
No current batch certificates or complete label were independently reviewed. The FDA entry for corn silk as a food flavoring agent does not independently inspect this seller's product.
Can this herbal tea treat urinary or metabolic problems?
No treatment or prevention benefit is promised. Evidence from animal experiments and ingredient reviews should not be presented as proven effects of this retail tea.
