Kew accepts Dendrobium fimbriatum Hook. in the orchid family (Orchidaceae), a pseudobulbous epiphyte or lithophyte native from the Himalaya to southern China and Indochina. “Fringe-lipped dendrobium” is the common English name; Shihu / Dendrobium stem is the Chinese materia-medica name.

The 2015 Chinese Pharmacopoeia entry reproduced by Westlake ShennongAlpha defines Shihu as fresh or dried stems from cultivated Dendrobium sources, explicitly including D. fimbriatum. It records the pooled materia medica as slightly cold and sweet, entering the Stomach and Kidney channels, with traditional actions of benefiting the stomach, generating fluids, nourishing yin, and clearing heat. These are traditional-system descriptions, not conclusions from clinical trials.

The medicinal-plant database of Kumamoto University’s School of Pharmacy identifies D. fimbriatum var. oculatum, gives the stem as the medicinal part and Shihu as the drug name, and summarizes reported traditional uses such as clearing heat, anti-inflammatory use, tonic use, and support for digestion. The university cautions that effects reported in references are not necessarily scientifically established. Keep that source’s variety and context explicit; do not transfer every historical use to an unidentified species or product.

A pharmacopoeia entry provides identity and quality specifications; it does not establish that every commercial product treats a disease or that each species source has the same clinical effects. Kumamoto University lists fimbriatone, confusarin, and rhein in its record for var. oculatum. Finding a compound in a sample does not establish a stable amount across growing regions or prove that the stem treats inflammation, fever, sexual dysfunction, or digestive disease in people.

Kumamoto presents this as composition and traditional-use information from references; its page does not present clinical trials establishing efficacy. The reviewed evidence does not establish a human dose-response, clinical benefit, equivalence between fresh and dried stems, or equivalence between extracts and raw material. Findings for the Dendrobium genus generally cannot automatically be assigned to D. fimbriatum.

Trade records are separated into the CITES section below so a reported transaction is not mistaken for medical evidence.

The references reviewed do not provide a complete clinical toxicology assessment, drug-interaction profile, contraindication list, or species-specific safety threshold for D. fimbriatum. Do not assume the plant is harmless because it appears in a pharmacopoeial materia-medica entry, and do not label a particular herb pair “toxic” without a source documenting that combination. Do not collect wild orchids or use an unidentified ornamental plant as medicine; products sold as Shihu can include multiple species and vary in quality.

People who are pregnant or breastfeeding, children, people with chronic conditions, and anyone taking medicines should ask a qualified clinician or pharmacist before considering a Shihu product. This is a precaution based on missing interaction data and product variation, not a claim that a specific interaction has been demonstrated. A trade name, AI image, CITES code, or traditional description cannot replace authentication and testing for identity, constituents, contaminants, and residues.

No formula was verified that names Dendrobium fimbriatum itself, its stem part and preparation, and a specific combination ratio. The Shihu monograph is pooled across several Dendrobium sources, so it cannot by itself identify a formula using this exact species. The profile therefore does not attach unrelated herb photographs to an invented pairing, recommend a beneficial ratio, or turn a recorded amount into personal advice.

The pooled monograph excerpt records 6–12 g for dried material or 15–30 g for fresh material, added late in decoction. These amounts belong to the multi-species Shihu entry; they are not a self-use dose for D. fimbriatum. Treat them only as an example of how the source records an amount, not as directions to ingest it. No reviewed source confirms a specific herb pairing that is toxic with this species; lack of a report does not mean every combination is safe.

Key features in the flowering illustration are a low clump, one bright yellow flower with many narrow radiating petals, and leaves divided into very fine, feathery segments. The Royal College of Physicians describes a mound of fine foliage and buttercup-like spring flowers; Kew records a temperate perennial. Colors and details in AI artwork follow those descriptions but do not represent all natural variation. When dried

, flowers fade and stems/leaves collapse, reducing diagnostic features; a dried bundle cannot be securely identified by sight alone. An older CITES proposal notes that several perennial Adonis species look similar and may be confused in traded material. Do not forage this toxic plant for identification practice.
