1. Overview

Zào Jiǎo Cì (皂角刺) — Gleditsia sinensis (spine) — is known in English as Chinese honeylocust spine / Gleditsia thorn. It belongs to the category of Herbs that clear Heat and resolve toxicity in the Chinese Materia Medica and is used in Chinese herbal medicine as a component of classical herbal formulas and tailored prescriptions.

I prescribe Zào Jiǎo Cì as part of bespoke herbal formulas from pharmaceutical-grade granules sourced from Sun Ten in Taiwan. 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. Carbuncles, abscesses and boils in the suppuration stage — to promote discharge

5. Modern research

Gleditsia sinensis spine (Zao Jiao Ci) has emerged as one of the most important fertility herbs in modern TCM practice, particularly for PCOS and anovulation. Its traditional use for 'dispersing masses and drawing out toxin' maps directly onto the Phlegm-Damp obstructing the ovaries pattern in PCOS. Key bioactive constituents include flavonoids (luteolin, quercetin), saponins, phenolic acids and sterols. Research confirms significant anti-inflammatory effects, antibacterial activity, anti-tumour properties (particularly relevant to PCOS-associated endometrial and ovarian cancer risk), and — critically — ovulation-stimulating effects via oestrogen receptor modulation. Clinical research from Chinese hospitals confirms Zao Jiao Ci-containing formulas improve ovulation rates in PCOS comparable to clomifene, with fewer side effects.

6. Incompatibilities

Zào Jiǎo Cì (皂角刺) Chinese honeylocust spine / Gleditsia thorn 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.

7. Cautions and contraindications

Avoid during pregnancy — the Blood-moving and toxin-drawing properties may trigger miscarriage. Avoid in patients with ongoing suppurative infections at the drainage stage. Avoid in deficiency without stasis or Phlegm.

Pattern contraindications

Contraindicated in Cold patterns and Yang deficiency. Short courses preferred — long-term use of strongly cold Heat-toxicity herbs damages Spleen Yang and digestion.

Modern drug interactions

Several Heat-toxicity herbs (e.g. Jin Yin Hua, Lian Qiao, Pu Gong Ying) are generally well tolerated. Avoid combining with strong immunosuppression without practitioner review.

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 Chinese herbs without professional guidance. Dr (TCM) Attilio D’Alberto is a member of the RCHM with over 25 years of clinical experience.
