Zao Jiao Ci Uses, Research and Safety Guide

You might see Zao Jiao Ci being marketed and sold as Chinese honey locust thorn, Gleditsia thorns or by the Latin name for the plant material of dried thorn of Gleditsia sinensis – in Chinese medicine it’s been used for centuries as a herbal ingredient, and therefore is known by the Chinese name for the herb itself: Zao Jiao Ci. And there are many wellness users and even buyers of herbs who first encounter this herb by the name of Gleditsia thorns, Chinese honey locust thorn or by the Latin name for it: Spina Gleditsiae.
Interest in Zao Jiao Ci has increased recently for two different reasons. On the one hand, users of traditional medicine are interested to learn more about the applications of this herb and to determine whether it can be used in modern herbal remedies. On the other hand, buyers, distributors and producers of herbal remedies are interested to obtain more information on the quality of the raw material, on the forms in which it is sold on the market, on its safety and on its current applications. A review of Gleditsia thorns would thus need to cover both aspects and provide a summary of tradition, research, safety and sourcing.
What Is Zao Jiao Ci?
Zao Jiao Ci is the Chinese name for dried thorn of Gleditsia sinensis. Gleditsia thorns or Gleditsia spine are sometimes found in the herbal trade. The dried thorn is also referred to as Spina Gleditsiae in traditional medicine references.
The plant material in question falls into the plant medicine category. The material used is the thorn of Gleditsia trees as opposed to leaves, flowers, seeds or roots. Correct identification is crucial when purchasing this material as thorns can be easily confused with other parts of the Gleditsia tree such as pods and seeds. Each part of the tree can have its own unique uses in traditional remedies as well as commercial specifications.
Common Names Used in Trade and Search
Some of the names for herbs and plants mentioned in product listings, in articles, on import documents and in herbal dictionaries are used for search and sourcing for the same plant material.
| Name | Where It Is Commonly Used |
|---|---|
| Zao Jiao Ci | Chinese medicine and TCM content |
| Spina Gleditsiae | Pharmacopoeia-style and research references |
| Gleditsia thorns | Herbal trade and product pages |
| Gleditsia spine | Product specification and export wording |
| Chinese honey locust thorn | Consumer education and botanical content |
For a herbal brand or importer, using the correct terms when referring to quantities will help prevent errors when inquiring, receiving quotations, labeling products and creating content for said products.
How Has Zao Jiao Ci Been Used in Traditional Chinese Medicine?
Herbs within Traditional Chinese medicine are often described by language systems that are distinct from that found within modern pharmacology. In the case of Zao Jiao Ci, for example, it is frequently associated with functions to reduce swelling, to expel toxin and to allow pus to be discharged. It is essential to distinguish between these functional descriptions derived from a past medical era and any current medical use to which this herb might be put.
The plant Spina Gleditsiae has been traditionally used to treat both external and internal swelling, sores, carbuncles, abscesses, and congealed masses. Today in Chinese herbal medicine practice, however, it is more commonly combined with other herbs in formula than sold as a single herb for self-treatment.
Why Traditional Context Matters?
As an individual ingredient Zao Jiao Ci can be used patternally, taking into consideration the individual’s particular presentation, as well as their physical constitution and the characteristics of other herbs within a formula. It can also be chosen in terms of form and size, such as pill or powder, and in terms of how it combines with other individual herbs. In this regard it is in sharp contrast to most products which are purchased on line for general health and wellbeing.
However, “Zao Jiao Ci benefits” is too simple a search query for readers. What they are really looking for is a more detailed search question such as: Under what circumstances did the Chinese use to employ Zao Jiao Ci and what are the safety limits for its use today?

What Does Modern Research Say About Gleditsia sinensis Thorns?

Modern research on Gleditsia sinensis thorns does not intend to replace traditional knowledge, it rather adds another layer to it. Laboratory investigations of the extracts from thorns of Gleditsia sinensis as well as their chemical markers and biological activity are very valuable for research of raw materials, for development of new products and for scientific content of them. However, these findings should not be misused for promises of treatment.
One of the active areas of research with anti-inflammatory effects is to study the bioactivity of extracts from thorns of Gleditsia sinensis in cell-based bioassays. In addition, there have been many reports on the bioactive compounds such as flavonoids and phenolic compounds, including, but not limited to, catechin, epicatechin, eriodictyol, quercetin, and caffeic acid, which are found in this plant.
What Research Can Tell Buyers?
The research can be beneficial to the buyer in three different ways. Firstly, it confirms that the name Gleditsia thorns are not being misused as a folk name and that it is being studied as a herbal material. This research can provide quality-control tests with compounds to test for when establishing criteria for testing herbal material for quality. Lastly, this research can be beneficial in providing a more responsible education to the buyer as to the ingredients of a product, without exaggeration by companies that are selling products made with these ingredients.
Research to support a sourcing conversation is all well and good but batch inspection, verification of supplier identity, control of moisture content, verification of packaging details and local regulation all still need to be done.
What Research Cannot Prove Yet?
Most of the studies on Zao Jiao Ci were conducted in the lab or in the early stages of research, thus they cannot be used as the evidence of clinical facts for marketing purposes. A responsible article or product description should not claim that Zao Jiao Ci can cure inflammation, tumors and replace with drugs for treatments.
Gleditsia sinensis thorns are traditionally used in Chinese medicine and have been subject of modern studies on their biological activities.
What Safety Notes Should Be Considered?
Safety is one of the key search terms when it comes to traditional herbs. Because Zao Jiao Ci is not a common herbal tea ingredient for experimenting with in everyday life, we supply it as a traditional medicinal material. For that reason, people are searching for information on Zao Jiao Ci side effects and Zao Jiao Ci contraindications. This information is intended to serve as practical limits rather than to advertise this product.
Pregnant women, breastfeeding women, children, people with chronic diseases, people on medications, and people with allergies should seek advice from qualified health care practitioners before using traditional herbs. Similarly, people currently on a TCM formula should seek advice from their health care practitioner before adding single herbs, as this can change the entire direction of the formula.
Practical Safety Rules for Readers and Buyers
Responsible use starts with basic caution:
-
Do not use Zao Jiao Ci for self-diagnosis.
-
Do not treat online dosage notes as personal medical advice.
-
Do not mix it with other strong herbs without professional input.
-
Do not use damaged, moldy, damp, or unidentified raw material.
-
Do not make disease-treatment claims in product marketing.
-
Check local rules for import, sale, labeling, and permitted claims.
Safety for B2B buyers also pertains to safety of documentation to prevent risk of wrong product. Clearly labeling product with Name, Botanical Source, Origin, Batch, Packaging Method, and Intended Use Category can save many headaches down the road.
How to Judge Quality When Buying Dried Gleditsia Thorns?
Quality for commercial sourcing of Gleditsia thorns goes beyond how they look. They should look like what you ordered, have dryness that stays constant, and be properly packaged for storage and travel.
The Buyer will look at the raw material quality and also at the suppliers process for checking bulk Gleditsia thorns. A clean looking material batch is a good start but this is not enough. The supplier must also be able to supply and communicate a set of product specifications and also be able to repeat an order and supply material of a stable quality.
Buyer Checklist for Gleditsia Thorns
| Checkpoint | Why It Matters |
|---|---|
| Botanical source | Helps confirm the material is Gleditsia sinensis thorn |
| Dryness | Reduces storage risk and quality loss |
| Impurity level | Affects processing, inspection, and customer acceptance |
| Batch consistency | Matters for wholesale and formula production |
| Packaging | Protects dried thorns during shipping and warehousing |
| Supplier experience | Helps with export, documentation, and repeat purchasing |
In order to sell through herbal shops, the product must look clean and have appropriate retail packaging. However, as a manufacturer or brand of herbal products, you will be more concerned with a distributor’s ability to supply the correct volume, process the products as required, allow for appropriate inspections, and ensure a suitable long term supply.
Why Does Responsible Sourcing Matter for Herbal Brands?

Traditionally Chinese medicinal herbs were for sale in local shops, but today Gleditsia thorns could go through the hands of wholesalers, online herbal retailers, herbal formula manufacturers, health and wellness product companies, and importers. Each of these is a new actor with new needs.
For the small online store clear English product names, safe storage of products and packaging of small quantities may be needed. For the larger herbal company bulk supplies of herbal raw materials are needed on a regular basis and with a clear traceable origin. For the distributor mixed categories of plant medicines from one supplier to keep communication costs down.
Supplier selection also affects the quality of a product that is purchased. Questions to consider are: the form of a product, its origin, how is it packaged, the minimum order that one can place with a supplier, the supplier’s export experience, and whether or not this supplier is also able to provide related Chinese medicinal herbs from the same category.
