What are the morphological characteristics of this plant?

Euphorbia kansui has a perennial, herbaceous growth habit characterized by upright, fleshy stems that typically reach heights of 30 to 100 centimeters. The leaves are arranged alternately along the stem and possess an elliptical to lanceolate shape with smooth margins. These plants produce small, inconspicuous flowers organized into specialized structures called cyathia, which are clustered in terminal umbel-like cymes. A distinguishing morphological feature is the presence of a milky white latex that flows from the stems when injured. The root system is generally shallow but robust enough to support its upright structure.

What is the geographical distribution of this plant?

This plant is native to the subtropical and temperate regions of East Asia, specifically spanning across parts of China, Japan, Korea, and Taiwan. It thrives in various habitats ranging from coastal areas to mountain slopes where light is abundant. Within these regions, it is frequently found growing in sandy soils or rocky crevices. Its distribution is closely tied to mild climates that provide sufficient moisture and warmth. While its primary range is concentrated in these specific Asian territories, its ecological niche remains relatively localized.

How is this plant cultivated?

This plant requires well-draining sandy or gravelly soil and full sun exposure to thrive in warm, arid climates.

Growers must ensure the substrate allows for rapid drainage to prevent root rot, which is a common issue for this succulent species. During the active growing season, provide moderate watering, but allow the soil to dry completely between applications. It is best to avoid fertilizing heavily, as minimal nutrients are sufficient for its slow growth rate.

Because the milky sap is highly irritating to the skin and eyes, careful handling is essential during planting and maintenance.

What parts of this plant are used medicinally?

This plant Euphorbia kansui provides medicinal benefits through the use of its milky sap, root, and tuber. The milky sap is often extracted for its specific chemical properties used in various traditional treatments. Both the root and the tuber are harvested and processed to create decoctions or topical applications. These underground components are valued for their ability to address different ailments in traditional medicine. Careful preparation of these specific parts is essential to ensure they are used correctly for therapeutic purposes.

According to a study published by "Plant physiology and biochemistry : PPB", Euphorbia kansui Liou is a unique traditional Chinese medicinal herb. The milky sap proteins of the plant play important roles in the synthesis and transport of its biologically active substances. A proteomic approach was used to identify a total of 125 milky sap proteins associated with general metabolism, disease and defense, and the development of laticifers. Through this analysis, 19 differentially expressed proteins at two different developmental stages of laticifers were successfully detected. These proteins, including peroxidase and the cytochrome P450 mono-oxygenase superfamily, may be involved in plant physiology and secondary metabolite synthesis.

What traditional systems uses this plant?

This plant, Euphorbia kansui, has been utilized in Traditional Chinese Medicine for centuries to treat various conditions related to swelling and stagnation. Practitioners historically prepared the plant to address issues such as abscesses, goiters, and certain types of skin lesions. The milky latex extracted from the stem serves as the primary medicinal component in these ancient formulations. It is often employed to promote the dissipation of phlegm and to alleviate painful swellings in the body. Because of its potent caustic properties, historical applications required precise dosing to avoid tissue damage.

According to a study published by "Journal of separation science", the processing of Euphorbia kansui requires appropriate parameters to optimize the Paozhi method of traditional Chinese medicine. Using untargeted metabolomics, researchers screened out 310 differential compounds during the vinegar-baking process. These compounds were categorized into 6 different groups, including diacylglycerols and triacylglycerols which increased with baking time, while ingenane-type diterpenes, jatrophane-type diterpenes, fatty acid esters, and fatty acids showed decreasing trends. Although diterpenes did not correlate with baking time, only 2 specific compounds, 13-Hydroxy-9,11-octadecadienoic acid and its isomer 9-Hydroxy-10,12-octadecadienoic acid, were validated to differentiate commercial vinegar-baked Euphorbia kansui.

What are the herbal preparations of this plant?

This plant is used to create diverse medicinal herbal preparations including 60% EtOH extract, EK stir-fried with vinegar, Shizaotang, VEK powder, and ethyl acetate extracts. Traditional practitioners often utilize the EK stir-fried with vinegar method to modify the plant's chemical properties for specific therapeutic applications. The Shizaotang formula represents a complex decoction that integrates the plant into a multi-herb system. Laboratory researchers frequently utilize both 60% EtOH extract and ethyl acetate extracts to isolate bioactive compounds for study. Additionally, the VEK powder serves as a concentrated form of the botanical material used in various medicinal contexts.

According to a study published by "Journal of ethnopharmacology", the root of Euphorbia kansui S.L.Liou ex S.B.Ho possesses a therapeutic effect on malignant ascites. In a H22 mouse hepatoma ascites model, 3-O-(2'E,4'Z-decadienoyl)-20-O-acetylingenol and ingenol were administered at doses of 110.14, 50.07, and 27.54 mg/kg over seven days. When Euphorbia kansui is processed with vinegar, the major diterpenoid 3-O-EZ can convert into ingenol. This vinegar-processing results in a decreasing rate of 3-O-EZ in VEK of 19.14% and an increasing rate of ingenol in VEK of 92.31%. These substances work to reduce ascites volumes, down-regulate the expression of AQP8, AQP2, and V2R, and involve metabolic pathways such as glycerophospholipid and arachidonic acid metabolism.

What side effects this plant can have?

This plant can cause acute toxicity through the ingestion of its chemical components, leading to severe gastrointestinal injury and significant intestinal irritation. Consumption of the species often results in intense abdominal pain, vomiting, and diarrhea. Beyond the digestive tract, the plant is known to cause hepatotoxicity in humans and animals. This toxicity can manifest as serious liver function impairment and permanent organ damage. Such physiological reactions underscore the extreme danger associated with accidental exposure to its toxic sap and tissues.

According to a study published by "Molecules (Basel, Switzerland)", Euphorbia kansui exhibits severe toxicity that restricts its clinical application. The main toxic ingredients are diterpenoids, specifically 3-O-(2'E,4'Z-decadienoyl)-20-O-acetylingenol, also known as 3-O-EZ. This 3-O-EZ component can increase malondialdehyde (MDA) content and reduce glutathione (GSH) content. It causes embryo oxidative damage by inhibiting the activity of succinate dehydrogenase (SDH) and superoxide dismutase (SOD). Additionally, 3-O-EZ induces inflammation and apoptosis through the elevation of IL-2 and IL-8 contents and the activation of caspase-3 and caspase-9 activity.

The main side effects this plant can have are shown in the list below.

  • acute toxicity
  • gastrogastrointestinal injury
  • hepatotoxicity
  • intestinal irritation
  • liver function impairment

What herbs are paired with Euphorbia kansui?

This plant Euphorbia kansui is traditionally paired with herbs such as Radix Rehmanniae, Radix Paoniae Rubra, and Radix Angelicae Sinicae to treat blood stagnation and dissipate blood stasis.

These combinations aim to balance the plant's powerful ability to break up blood clots with more nourishing or moving agents. Using Radix Rehmanniae helps to nourish the blood, which prevents the harsh nature of the Euphorbia from causing excessive bleeding. Adding Radix Paoniae Rubra can enhance the effect of moving the blood while protecting the yin aspects of the body.

Such carefully constructed formulas are essential to mitigate the toxicity and intensity of the herb during clinical application.
