Mei Gui Hua (Young Flower of Chinese Rose (Bud))

Chinese Herb Actions

Chinese Herb Dosage

• What is the typical dosage of Mei Gui Hua?

  Roughly 1.5–6 g in decoction — this is the range this site records from published reference. Other standard references give approximately 3–6 g, which sits inside the same window. The part used is the unopened or just-opening flower bud.

  • Aromatic handling — like other fragrant volatile-oil-bearing flowers, it is traditionally not cooked hard or long; it is commonly added late to a decoction, or simply steeped as an infusion in hot water.
  • As a tea — a few buds steeped in hot water is the everyday domestic form. This is a food-grade preparation and is generally at or below the low end of the medicinal range.
  • Low dose is the norm — the small dose range is not an accident of custom; the herb is valued for gentleness, and larger doses are not how it is traditionally used.

  Small variation between references. Published sources give slightly different lower bounds (about 1.5 g versus about 3 g). We treat this as a difference of editorial convention rather than a real disagreement, since the upper bound of roughly 6 g is consistent across them.

Chinese Herb Contraindications & Cautions

• Are there cautions for Mei Gui Hua? Is it safe?

  This site’s record lists no traditional contraindications, and no toxicity is noted — rose bud is a food-grade flower with a long history of everyday use as a tea. The sensible cautions are the general ones that attach to any aromatic, warm, qi-moving herb rather than anything specific to this plant.

  • Yin deficiency with heat — warm, aromatic, moving herbs are conventionally used carefully where yin or fluids are already depleted. Mei Gui Hua is among the mildest of them, and is often chosen for exactly this reason, but the general principle still applies.
  • Pregnancy — not documented as contraindicated in the sources we could verify. Its blood action is described as harmonising rather than invigorating, so it does not carry the standard blood-mover pregnancy caution that Yue Ji Hua does. Practitioner guidance is still the appropriate route in pregnancy.
  • Allergy — as with any botanical taken as a food, individual sensitivity to roses or to Rosaceae pollen is possible. This is a general allergen note, not a documented finding for this herb.

Chinese Herb Toxicity & Overdose

• Low. Mei Gui Hua is a food-grade edible flower with no significant toxicity reported at customary doses. It is consumed routinely as a flower tea, in liqueurs and jams, and as an edible-flower food ingredient, and the modern literature on it is overwhelmingly food-science and antioxidant chemistry rather than toxicology. No dose ceiling beyond the ordinary decoction range is documented in the sources we could verify.

  We found no reports of organ toxicity, no documented poisoning cases, and no restricted-substance listing for this herb. The realistic quality concerns are the ordinary ones for a dried flower — correct species, absence of pesticide residue, and proper drying — rather than intrinsic hazard.

Herb-Drug Interactions

• No well-established clinical herb–drug interactions are documented for Mei Gui Hua. It is a food-grade flower used at low doses, and we found no interaction studies, case reports or pharmacokinetic work specific to it. Laboratory work has identified enzyme-inhibitory constituents in rose flower extracts (for example alpha-glucosidase and protein tyrosine phosphatase 1B inhibition in vitro), but these are isolated-fraction findings in test tubes and do not establish a clinical interaction with any medication.

  Patients taking prescription medication should tell their prescriber about any herbal use, including herbal teas.

Chinese Herb Clinical Studies & Research

Provided as research context — a summary of published biomedical study, not a therapeutic or medical claim.

• Is there modern research on Mei Gui Hua (Rosa rugosa)?

  Yes — a large food-chemistry and antioxidant literature, one recent human physiological study of its aroma, and no clinical trials for the traditional qi-regulating indications. Chemically the flower is dominated by polyphenols: a 2019 profiling study of rose flower tea identified 23 phenolic compounds with quercetin glycosides as the principal component.

  • Human physiological study (aroma, 2025) — a study in 66 female participants recorded 32-channel EEG, blood pressure, pulse, heart rate, temperature and respiratory rate before and after exposure to volatile extracts of Rosa rugosa, Acorus tatarinowii and Cyperus rotundus, alongside a symptom checklist. The authors reported that the Rosa rugosa volatile modulated prefrontal–limbic network activity with reductions in somatisation and hostility scores. This is a single, unblinded, non-randomised physiological study of the inhaled aroma, not a trial of the herb taken internally, and the authors themselves call for randomised trials.
  • Antioxidant chemistry — a polysaccharide–peptide complex and a condensed tannin isolated from dried rose flowers both showed antioxidant activity in vitro, the tannin more strongly. An aqueous polyphenol extract of rose flower tea extended mean lifespan and improved oxidative-stress and heat tolerance in the nematode Caenorhabditis elegans.
  • Effects on gut bacteria — pulverised R. rugosa petal selectively inhibited E. coli, S. aureus, B. cereus and Salmonella while leaving bifidobacteria and lactobacilli largely unaffected; the hydrolysable tannins rugosin D and tellimagrandin II were identified as the active constituents. A laboratory selectivity finding, described by the authors as prebiotic-like.
  • Other in vitro findings — compounds from the flowers have shown HIV-1 reverse transcriptase inhibition and protein tyrosine phosphatase 1B inhibition in isolated-enzyme assays. Chemistry findings; no therapeutic claim follows from them.

  All of the above is laboratory, animal or single-study physiological work. There is no clinical evidence for the traditional Liver-qi indications.

  A naming note for the owner, flagged not changed. This site records the common name as “Young Flower of Chinese Rose (Bud).” The recorded pharmaceutical Latin, Flos Rosae Rugosae, is the flower of Rosa rugosa — the rugosa or beach rose, native to north-east Asia and naturalised (and treated as invasive) on European coastal dunes. The name “Chinese rose” conventionally refers to Rosa chinensis, which is the source plant of a different herb this site holds separately, Yue Ji Hua. The Latin binomial is correct; it is the English common name that risks collapsing the two. We have left the identity fields untouched and flag this for owner decision.

Chinese Herb Notes

• What is the difference between Mei Gui Hua and Yue Ji Hua?

  They are two different roses with two different emphases: Mei Gui Hua (Rosa rugosa) is primarily a qi-mover that secondarily harmonises blood, while Yue Ji Hua (Rosa chinensis, the “monthly rose”) is primarily a blood-invigorating herb with a menstrual focus. They are genuinely confusable — both are dried rose flowers, both enter the Liver, and both appear in gynaecological contexts — so this site records them as separate entries in separate categories.

  • Mei Gui Hua — Flos Rosae Rugosae. Sweet, slightly bitter, warm; Liver and Spleen. Filed under the herbs that regulate the qi. Its lead action is relieving constraint in the chest, flanks and epigastrium; the blood action is described as harmonising, which is deliberately weaker language than invigorating.
  • Yue Ji Hua — recorded on this site as Flos Et Fructus Rosae Chinensis. Sweet, warm; Liver only. Filed under the herbs that invigorate blood and remove stagnation. Its centre of gravity is menstrual: irregular or blocked menstruation from blood stasis.
  • Practical upshot — constraint, chest oppression, sighing, distension and appetite loss point to Mei Gui Hua; a frank blood-stasis menstrual presentation points to Yue Ji Hua. Because Yue Ji Hua is the more strongly blood-moving of the two, the usual pregnancy caution attaching to blood-invigorating herbs applies to it and not, in the same way, to Mei Gui Hua.

  How is Mei Gui Hua different from Jin Ying Zi?

  Completely different: Jin Ying Zi is a rose hip (the fruit), not a rose flower, and it is astringent rather than moving. This site records Jin Ying Zi as Fructus Rosae Laevigatae — the fruit of Rosa laevigata, the Cherokee rose — sour and astringent, neutral, entering Bladder, Kidney and Large Intestine, filed under the herbs that astringe, stabilise and bind. It is used to hold things in (leakage patterns), which is the functional opposite of a qi-mover. Sharing the genus Rosa tells you almost nothing about how these two are used.

  What is Mei Gui Hua commonly combined with?

  As a Liver-qi herb it sits naturally alongside the other constraint-relieving herbs this site records — Xiang Fu (also Liver, also qi-regulating, stronger and more targeted at menstrual pain) and Chuan Xiong (blood-in-the-qi, headache and menstrual pain) — and its own record singles it out as one of the most effective yet most docile of the qi herbs, which is why it is often the one chosen when a patient is depleted or sensitive.
