Whole garlic-chive leaves,
does it really help with Improved erectile function or sexual vitality?
research showsThe grade is ?. No human study was found that fed whole garlic-chive leaves and measured erectile or sexual function. Human chive-pill studies measured body composition and blood markers. The only human sexual-function material was an uncontrolled patent survey of an eight-extract mixture whose plant name was Allium ampeloprasum, not clearly garlic chives. There is no score.
ads claimCombining seed tradition, animal studies, and a mixed-extract survey does not establish a human effect of whole leaves. This verdict concerns the food leaf, not extract or dried pills.
Useful facts when choosing a product
- On 2026-08-02, PubMed exact query 「"Allium tuberosum"[All Fields] AND humans[Filter]」 returned 24 records; full screening found 0 eligible whole-leaf erectile or sexual-function studies. Chemistry, cell, animal, other-outcome, pill, and mixture records were excluded.
- On 2026-08-02, ClinicalTrials.gov exact query 「Allium tuberosum」 returned 0 trials. WHO ICTRP, CRIS, ChiCTR, and UMIN-CTR searches combining 「Allium tuberosum OR garlic chives OR Chinese chives」 with 「erectile OR sexual function OR IIEF OR libido」 found 0 eligible whole-leaf trials.
- On 2026-08-02, KCI, KoreaScience, RISS, ScienceON, DBpia, J-STAGE, CiNii, CNKI, and Wanfang searches combining the plant names with erectile and sexual-function terms found 0 eligible human studies; nonsexual pill studies, patents, animals, and seed experiments were excluded.
- Bencao Gangmu, ju entry, genuinely gives the name qi yang cao. The explicit 「return to kidney and strengthen yang」 wording belongs to the separate seed entry; Diannan Bencao's erectile statement also concerns seed. Leaf wording stops at warming the middle and supplementing deficiency and yang.
- Tradition was internally divided: Bencao Gangmu records a Qianjin Fang reading that it is not beneficial for patients, Tao Hongjing discouraged it, and Su Song encouraged regular use.
- This is a new whole-leaf food question, not an extract or powder-pill claim.
What the research actually shows
No human study fed whole garlic-chive leaves and measured IIEF, erection success, libido, or sexual function. Lee and Baek 2011 gave chive pills to 24 male high-school students for 10 weeks and measured body fat, lipids, and C-reactive protein. A 2013 study of 32 participants also used chive pills and measured body composition, liver enzymes, and immune outcomes, not sexual function. Patent KR20150030385A describes an uncontrolled 163-person survey of eight extracts including ginseng and maca, with no comparator, blinding, or p values; it names Allium ampeloprasum, so the chive identity is uncertain. Positive erection and sexual-behavior findings are animal experiments, many using chive seed.
Why this is classified as ?
No human study measured the claimed endpoint after whole-leaf intake, so the grade is ? and the score is null.
Counterpoint. Traditional naming and animal signals can motivate research but do not answer human efficacy.
Rejudgment record. Cross-check applied — Multilingual searches across international and Asian databases found no study feeding whole garlic-chive leaves to humans and measuring erectile or sexual function
