1. Overview

Shí Hú (石斛) is the dried stem of Dendrobium nobile (and related Dendrobium species), known in English as Dendrobium. It belongs to the category of Herbs that nourish Yin and is one of the principal moistening herbs used in Chinese herbal medicine for Stomach and Kidney Yin deficiency, depletion of body fluids and post-febrile recovery.

I prescribe Shí Hú as part of bespoke herbal formulas from pharmaceutical-grade granules sourced from Sun Ten in Taiwan — independently tested to the highest international quality and safety standards. Herbs are always combined with other herbs selected to match the patient’s individual TCM pattern. Online consultations are available for patients who cannot attend my clinic in person.

2. Properties

3. Actions and indications

Principal actions

1. Nourishes Stomach Yin and generates fluids
2. Clears Heat and relieves thirst
3. Nourishes Kidney Yin and brightens the eyes

Indications

1. Stomach Yin deficiency with dry mouth, dry throat, low appetite, mild thirst and a peeled red tongue
2. Convalescence after febrile disease with fluid depletion
3. Kidney Yin deficiency with weak knees and low back, blurred vision, dizziness and tinnitus
4. Low-grade afternoon fever in Yin deficiency
5. Type 2 diabetes presenting as Stomach/Kidney Yin deficiency (within TCM Xiao Ke patterns)

4. Modern research

Dendrobium contains polysaccharides, bibenzyls (e.g. dendrobine), alkaloids, phenanthrenes and sesquiterpenoids. Studies report immunomodulatory, antioxidant, anti-inflammatory, hypoglycaemic and neuroprotective effects. Dendrobium polysaccharides have been investigated for glucose regulation in animal models of type 2 diabetes, consistent with traditional use in Xiao Ke (wasting-thirst) patterns. The herb is also under research for protective effects on gastric and ocular tissues.

5. Incompatibilities

Shí Hú (石斛) Dendrobium Stem is not listed in either of the two classical incompatibility texts — Shi Ba Fan (Eighteen Antagonisms) or Shi Jiu Wei (Nineteen Mutual Inhibitions). As with every Chinese herb it should be prescribed only as part of a balanced formula by a registered Chinese herbalist (RCHM), who will check for interactions with any other herbs and prescription medications you are taking.

6. Cautions and contraindications

Use with caution in patterns of pure Excess with Damp; the moistening nature can worsen Damp accumulation. Not appropriate as a single herb to address fatigue or low energy without a Yin-deficient pattern. Authenticated material is important; the international Dendrobium trade includes substitutions, and quality varies considerably.

Pattern contraindications

Use cautiously where Damp accumulation, Spleen Qi deficiency with loose stools, or Phlegm-Damp patterns are present — Yin tonics tend to be sweet and cloying and can aggravate Dampness if the digestive function is weak.

Modern drug interactions

Generally well tolerated. Some Yin tonics modulate the immune response — tell your GP if you take immunosuppressant medication, biologics or chemotherapy.

Important: Chinese herbs should always be prescribed by a fully qualified herbalist who is a member of the Register of Chinese Herbal Medicine (RCHM). Never self-prescribe or self-administer Chinese herbs without professional guidance. Dr (TCM) Attilio D’Alberto is a member of the RCHM and the British Acupuncture Council with over 25 years of clinical experience.

7. Treatment at my clinic

Every prescription is individually formulated following a full TCM assessment.
