Ye Ju Hua (Wild Chrysanthemum Flower)

Chinese Herb Actions

Chinese Herb Dosage

• What is the typical dosage of Ye Ju Hua?

  6–12 g in decoction, using the flower head, and it is also used externally as a wash or a poultice — the range and preparation recorded here. Materia medica consensus sits in the same place, generally 9–15 g, with the higher end reserved for the toxic-sore indications; some sources give a larger figure again for the fresh herb.

  • 6–12 g in decoction internally.
  • Part used: the flower — our record gives the pharmaceutical Latin as Flos Chrysanthemi Indici, the flower head of Chrysanthemum indicum.
  • External use — prepared as a wash, a soak, or a mashed poultice for sores, boils and itchy eruptions. For this herb the external route is a mainstream application, not an afterthought.
  • Not a tea herb. Ju Hua is drunk as a pleasant everyday infusion; Ye Ju Hua is markedly more bitter and is not used that way. If a chrysanthemum is being enjoyed as a beverage, it is almost certainly Ju Hua.

Chinese Herb Contraindications & Cautions

• Are there cautions for Ye Ju Hua?

  The main caution is the ordinary one for a bitter, cold, draining herb: it is not suitable for Spleen and Stomach deficiency with cold, and it is not intended for long or casual use. Sacred Lotus holds no recorded caution for this herb, so what follows is drawn from materia medica consensus and stated as reference information rather than as an internal record.

  • Spleen and Stomach deficiency with cold — avoid or use with care. A strongly bitter cold herb burdens a weak, cold digestion; nausea, poor appetite or loose stool are the expected result.
  • Not a daily tea. Because it looks and sounds like Ju Hua, Ye Ju Hua is sometimes drunk casually as an infusion. It is a stronger, more draining herb aimed at an acute presentation, and it is not appropriate for routine or prolonged self-administered use.
  • Pregnancy — not a recorded contraindication, but cold, draining, toxin-clearing herbs are generally used only under professional supervision in pregnancy. Precautionary note.
  • Asteraceae allergy — chrysanthemum belongs to the Asteraceae (Compositae) family. Contact sensitisation to chrysanthemums is well documented: a 21-year Danish patch-testing series found 111 of 191 patients with Compositae sensitisation reacted positively to chrysanthemum extract, most of them recreationally exposed (PMID 31483868). That is contact allergy from handling plants, a different exposure route from a decocted flower, but people with a known Compositae/daisy-family allergy have a reason to be cautious — particularly with the external washes and poultices, which put the herb directly on skin that is already broken or inflamed.
  • Sores and boils can be serious. The indications for this herb overlap with conditions that can require medical treatment. Spreading redness, fever or a rapidly worsening lesion is a matter for a clinician.

Chinese Herb Toxicity & Overdose

• No significant toxicity is documented for Ye Ju Hua at traditional doses. A comprehensive review of Chrysanthemum indicum covering botany, phytochemistry and pharmacology — more than 190 isolated constituents and around two thousand years of recorded medicinal use — records no established toxicity, while noting that resource availability, mechanistic research and quality control all remain insufficient (PMID 32431180). The absence of a toxicity finding in a literature this thin is not the same as a demonstration of safety. The one clearly documented adverse phenomenon is contact allergy to the plant family rather than systemic toxicity of the decocted flower (PMID 31483868).

Herb-Drug Interactions

• No well-established clinical herb–drug interactions are documented for Ye Ju Hua. No interaction study specific to this herb was located, and the comprehensive review of the species explicitly identifies mechanistic research and quality control as insufficient (PMID 32431180) — so interaction potential is under-studied rather than ruled out. On precautionary grounds only: the herb is used in the traditional record for Liver-heat presentations that include headache and red eyes, and our record carries a blood-pressure annotation (flagged in the actions section as not a classical action and not supported by located trial evidence); patients taking antihypertensive medication should raise its use with their prescriber rather than assume no effect either way. (Flagged for practitioner confirmation.)

Western / Biomedical Research

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 Ye Ju Hua (Chrysanthemum indicum)?

  Yes — the phytochemistry is well mapped and the anti-inflammatory and antimicrobial activity is consistently reported in preclinical work, which is at least the right general direction for a toxin-and-sores herb. Human clinical evidence is essentially absent. A 2020 comprehensive review identifies more than 190 chemical constituents in Chrysanthemum indicum — flavonoids, terpenoids, phenylpropanoids and phenolic acids — and records anti-inflammatory, antioxidant, antimicrobial, anticancer, immune-regulating and liver-protective activities in extracts and isolated compounds, while noting that mechanism and quality control remain insufficiently researched (PMID 32431180).

  • Anti-inflammatory and immunomodulatory — extracts of the inflorescence (the flower head, which is the part used medicinally) showed anti-inflammatory and immunomodulatory activity in a 2005 study in the Journal of Ethnopharmacology (PMID 16029939). This is the most direct preclinical parallel to the traditional heat-and-toxin action.
  • Compared directly with Ju Hua — a 2025 review examined Chrysanthemum morifolium and Chrysanthemum indicum side by side for antimicrobial, anti-inflammatory, antioxidant and immunomodulatory properties, and concluded that their differing compound profiles and constituent concentrations point to differentiated therapeutic advantages rather than interchangeability (PMID 40176916). That is a modern chemical restatement of the traditional distinction described in the notes above.
  • Characteristic constituents — the sesquiterpenoid handelin, a marker compound of Chrysanthemum indicum, has been studied for effects on skeletal-muscle protein homeostasis and inflammation in cachexia and ageing models (PMID 38009816). Novel dimeric guaianolide sesquiterpenoids isolated from the flowers were reported in 2025 to affect hepatic lipid accumulation in laboratory models (PMID 39788286). Both are cell and animal work.
  • Polysaccharides — a 2025 review covers extraction, structural features and bioactivity of polysaccharides across the genus Chrysanthemum, an active area given the reported immunomodulatory effects (PMID 39753177).
  • As part of a formula — Chrysanthemum indicum is one of three herbs in the widely used Chinese preparation Xia Sang Ju, alongside Prunella vulgaris and mulberry leaf; a 2022 review of that formula’s phytochemistry, pharmacology and quality control notes that systematic clinical trials of it are still lacking (PMID 35814215).

  No controlled human trial of Ye Ju Hua as a single herb for any traditional indication was located. The evidence base is preclinical and mechanistic; the traditional use rests on materia medica consensus and long practice.

Chinese Herb Notes

• What is the difference between Ye Ju Hua and Ju Hua?

  They are two different plants used for two different things, and confusing them is the single most common error with this herb. Ju Hua is the gentle eye-and-wind-heat flower; Ye Ju Hua is the harsh toxin-and-sores flower. Sacred Lotus holds them as separate records in different categories, which is the clearest way to see the distinction.

  • Different species. Ju Hua is the cultivated Chrysanthemum morifolium (Flos Chrysanthemi Morifolii). Ye Ju Hua is the wild Chrysanthemum indicum (Flos Chrysanthemi Indici). Ye (野) simply means “wild”.
  • Different category. Ju Hua sits among the cool, spicy herbs that release the exterior — an exterior-resolving herb. Ye Ju Hua sits among the herbs that clear heat and eliminate toxins — an interior heat-toxin herb. They are not variants of one medicine; they do different work.
  • Different flavour. Ju Hua is recorded here as sweet and bitter; Ye Ju Hua as bitter and spicy, with no sweetness at all. The missing sweetness is the taste of the difference — Ye Ju Hua is distinctly, unpleasantly bitter, which is why it never became a tea.
  • Different channels. Ju Hua leads with the Liver (Liver and Lung); Ye Ju Hua leads with the Lung (Lung and Liver). Both touch the Liver, which is why both have some claim on red eyes — and that shared edge is exactly where the confusion starts.
  • Different target. Ju Hua: wind-heat colds, red and dry eyes, and ascending Liver yang with dizziness and headache. Ye Ju Hua: furuncles, carbuncles, deep-rooted boils, scrofula, eczema and itching — sores with heat and toxin, treated inside and out.
  • Different formulas. Ju Hua appears in Sang Ju Yin and Ling Jiao Gou Teng Tang in the Sacred Lotus formula records; Ye Ju Hua appears in Wu Wei Xiao Du Yin. Those three formulas are a fair summary of the two herbs’ separate territories.

  The practical rule: if the presentation is an infection-like sore, boil or eruption, it is Ye Ju Hua. If it is an early wind-heat cold or an eye complaint, it is Ju Hua. Substituting one for the other is not a mild adjustment.

  On temperature. Both herbs are recorded here as slightly cold. Materia medica consensus commonly describes Ye Ju Hua as the colder and stronger of the pair — some sources give it plainly as cold rather than slightly cold, and practitioners generally treat it as the more draining and more aggressive herb, less suitable for prolonged or casual use. Our identity fields have not been altered; the difference is flagged here so that readers comparing sources are not misled by the two records showing the same temperature. The direction of the difference is not in dispute: Ye Ju Hua is the harsher of the two.

  Is Ye Ju Hua the same as the chrysanthemum tea sold in shops?

  No. Chrysanthemum tea, and the dried flower heads sold for it, are Ju Hua — the cultivated flower, mild and faintly sweet. Ye Ju Hua is a smaller, more strongly aromatic wild flower with a sharply bitter taste and is used medicinally rather than enjoyed. A 2025 comparative review of the two species notes that although both are recorded in the Chinese Pharmacopoeia as heat-clearing and detoxifying herbs, their compound profiles and the concentrations of their core constituents differ, which the authors link to different therapeutic emphases (PMID 40176916).
