What are the morphological characteristics of this plant?
Euphorbia lathyris has an erect, herbaceous perennial habit characterized by thick, succulent stems that reach heights of up to two meters and lack true branches. The leaves are arranged in an alternate pattern along the stem and feature a distinctively oblong or lanceolate shape with entire margins. These leaves are typically a bright, yellowish-green color and possess a somewhat fleshy texture. The plant produces small, inconspicuous yellowish flowers held within specialized structures called cyathia at the ends of the stems. A defining morphological feature is the presence of a milky white latex that exudes from the stem and leaves when the plant tissue is damaged.
What is the geographical distribution of this plant?
This plant is native to the Mediterranean region, specifically encompassing areas of North Africa, Southern Europe, and parts of Western Asia. It thrives in various habitats ranging from coastal cliffs to arid rocky slopes where sunlight is abundant. Although its origins are centered around the Mediterranean basin, it has been introduced to other parts of the world through human activity. Some populations have become established in subtropical or temperate regions with similar climatic conditions. Its ability to tolerate dry environments allows it to spread across diverse landscapes within its broad range.
How is this plant cultivated?
This plant, Euphorbia lathyris, thrives in well-drained, sandy or loamy soils within USDA hardiness zones 7 through 10 and requires full sun exposure for optimal growth.
Growers should provide consistent moisture during the establishment phase but must ensure the medium does not become waterlogged to prevent root rot. Because this species is highly drought-tolerant once mature, it is an excellent choice for xeriscaping in arid climates. Caretakers must exercise extreme caution during cultivation because the milky white latex produced by the stems is a potent skin irritant and can cause temporary blindness if it contacts the eyes.
Regular pruning can help maintain the structure of the large, upright stalks as they reach their full height.
What parts of this plant are used medicinally?
This plant Euphorbia lathyris provides medicinal applications through its aerial parts, hairy roots, leaves, roots, and seeds. The aerial parts and leaves are often processed to create topical treatments for skin conditions. Extracts derived from the root and the specialized hairy roots are utilized in traditional formulations to address various internal ailments. Additionally, the seeds contain specific compounds that contribute to the plant's overall pharmacological profile. Each of these components must be handled with caution due to the potent nature of the plant's chemical constituents.
According to a study published by "Biological & pharmaceuatical bulletin", a methanol extract of the aerial parts of Euphorbia lathyris L. was used to activate reporter gene expression in the human pancreatic cancer cell line MIA PaCa-2. Researchers isolated 2 lathyrane-type diterpenoids, identified as euphorbia factor L1 (EFL1) and L3 (EFL3), from these aerial part extracts. Treatment with EFL1 or EFL3 increased levels of phosphorylated inositol-requiring enzyme 1 alpha (IRE1α), activating transcription factor 4 (ATF4), and CHOP. These factors are involved in the endoplasmic reticulum (ER) stress pathway and cleaved poly (ADP-ribose) polymerase protein (PARP) as apoptotic markers. Consequently, EFL1 and EFL3 may be useful in the development of treatments for pancreatic cancer.

What traditional systems uses this plant?
This plant, Euphorbia lathyris, has been historically utilized in various traditional medicinal systems to treat skin conditions, inflammatory ailments, and certain types of tumors. In Traditional Chinese Medicine, specific preparations of the plant have been applied to address localized swellings and topical irritations. Historically, various cultures used the caustic milky latex derived from the stems to cauterize warts or remove cutaneous growths. Beyond topical applications, some ancient practices experimented with controlled internal doses for purgative effects, though its high toxicity required extreme caution. These traditional uses reflect a long-standing human effort to harness the plant's potent chemical properties for therapeutic purposes.
According to a study published by "Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica", nrDNA ITS sequences can be used as molecular markers to identify Tibetan herb Chuan-Bu and Traditional Chinese Medicines from the same genus Euphorbia as E. lathyris. The study examined species within the genus, noting that the size of the 5.8S coding region was 164 bp for all species examined. Within the genus, there were 8 point mutations in the 5.8S coding region. The research utilized sequences of ITS1 and ITS2 to differentiate species, such as those measuring 261 bp and 221 bp respectively. These molecular markers assist in identifying medicinal plants within the same genus as E. lathyris.

What are the pharmacological activities of Euphorbia lathyris?
This plant has anticancer and antitumor properties driven by its ability to exhibit significant cytotoxicity and the inhibition of cell proliferation in various cancer cell lines. These pharmacological activities allow the plant extracts to interfere with the growth and survival of malignant cells. Beyond direct cellular interference, the substance has demonstrated a capacity for the prevention of malignant ascites effusion in experimental models. Research suggests that these multifaceted biological effects stem from the presence of specific diterpene esters found within the species. Consequently, Euphorbia lathyris serves as a subject of interest for developing new therapeutic strategies against tumor progression.
According to a study published by "Phytotherapy research : PTR", Euphorbia lathyris is identified as a source of diterpenoids. These compounds are part of a group of natural substances found in many toxic Chinese medicines used for different stages of cancer. Out of at least 120 species of poisonous botanicals, animals and minerals, more than half have been found to possess significant anticancer properties. The study reviews these various structures to understand how to increase antitumor activity or reduce side effects.
The primary pharmacological activities of this plant are shown in the list below.
- anticancer
- antitumor

What medicinal compounds this plant contains?
This plant contains several potent medicinal compounds including lathyrol, ingenol, jolkinol A, lathyrisone A, and spirolathyrisins B-D. These diverse diterpenoids and related secondary metabolites are known for their significant biological activities in pharmacological research. Specifically, compounds like ingenol have demonstrated potential in cancer research due to their ability to interact with cellular signaling pathways. The chemical structure of these substances allows for specialized interactions within human physiological systems. Scientists continue to investigate how these unique molecules can be synthesized or extracted for future therapeutic applications.
According to a study published by "The Plant journal : for cell and molecular biology", Euphorbia lathyris contains macrocyclic diterpenoid esters that hold significant medicinal value due to their structural diversity and biological efficacy. Two specific O-acyltransferases, ElBAHD16 and ElBAHD35, were identified from the diterpene biosynthetic gene cluster of Euphorbia lathyris to contribute to this biosynthesis. These enzymes exhibit mono-acylation activities toward the hydroxy groups of substrates such as 7-hydroxylathyrol and lathyrol. ElBAHD16 demonstrates regioselectivity toward the 7-OH group of 7-hydroxylathyrol and produces 3 different mono-acylation products. In contrast, ElBAHD35 mediates mono-acetylation reactions with acetyl-CoA through specific recognition for the 5-OH group of 7-hydroxylathyrol and lathyrol.

What herbs are paired with Euphorbia lathyris?
This plant, Euphorbia lathyris, is rarely paired with culinary herbs because its toxic milky latex makes it unsuitable for direct consumption or flavoring.
In garden design, it is most commonly paired with drought-tolerant herbs like lavender, rosemary, and sage to create a textural Mediterranean aesthetic. These pairings work well because the architectural, upright stems of the euphorbia complement the fine foliage of the woody herbs. Careful separation is necessary to ensure that the caustic sap does not contaminate the edible plants in the vicinity.
Such combinations are intended for visual interest rather than any functional herb infusion or medicinal mixture.
