Herbal medicines are the earliest treatments that humanity is aware of. India is renowned around the world for its Ayurvedic medicine. Traditional uses of Euphorbia hirta include the treatment of tumors, diarrhea, jaundice, acne, gonorrhea, gastrointestinal issues, and respiratory illnesses (cough, coryza, bronchitis, and asthma). Alkanes, triterpenes, phytosterols, tannins, polyphenols, and flavanoids are said to be present. The therapeutic benefits, chemical make-up, and other significant features of Euphorbia hirta are discussed in this review.
What location is home to Euphorbia hirta?
Habitat: In human-altered habitats, euphorbia hirta flourishes (roadsides, fields and yards). Distribution: Euphorbia hirta can be found in Florida, the entire Caribbean, the Lucayan Archipelago, and tropical and subtropical climates all over the world.
What are Euphorbia’s side effects?
Euphorbia cyparissia is NOT SAFE to consume when taken orally. The plant contains compounds that can lead to cancer as well as a deadly white milky liquid known as white latex. Products that are either fresh or dried are dangerous. Euphorbia cyparissias can make people feel sick, throw up, have diarrhea, and their mouths may burn. When used in large doses, it produces collapse, dilated pupils, dizziness, severe diarrhea, near unconsciousness, and irregular pulse.
It is NOT SAFE to apply Euphorbia cyparissias to the skin. It can lead to blisters, irritation, blistering, reddening, rash, and itching. Getting Euphorbia cyparissias in the eye can damage the cornea and other components of the eye, as well as cause swelling of the eye and eyelid.
Are humans poisoned by euphorbia?
The milky secretion of the Euphorbia plant, sometimes known as latex, is extremely poisonous and irritating to the skin and eyes. This study provides an illustration of the range of ocular inflammation brought on by unintentional ingestion of Euphorbia plant latex. Three patients came in with recently developed accidental ocular exposure to milky sap of a Euphorbia species. In all cases, there was a significant burning sensation along with vision blur. Visual acuity decreased to counting fingers from 20/60. Clinical findings ranged from anterior uveitis to secondary increased intraocular pressure, mild to severe corneal edema, epithelial defects, and keratoconjunctivitis. With active supportive treatment, all symptoms and indicators disappeared after 10 to 14 days. When handling euphorbia plants, wear safety goggles. Asking the patient to bring a sample of the plant for identification is usually advisable.
Trees, succulents, and herbaceous plants all belong to the Euphorbiaceae genus.
[1] There are numerous kinds of Euphorbia that can be found growing in the wild or in gardens or homes as cultivated examples. The milky sap or latex is poisonous and can cause severe skin and eye problems. From moderate conjunctivitis to severe kerato-uveitis, ocular toxic response can vary [2]. There are a few case reports of people losing their sight permanently as a result of accidentally putting Euphorbia sap in their eyes. [24] Corneal involvement typically proceeds in a predictable order, with edema getting worse and epithelial sloughing on the second day. [3,5] Some species are thought to be more poisonous than others. [6] The inflammation usually goes away without leaving any aftereffects when it is promptly treated and carefully maintained. Here, we show three instances of ocular toxicity brought on by three distinct Euphorbia species: E. trigona (African milk tree), E. neriifolia (Indian spurge tree), and E. milii (Crown-of-thorns houseplant).
How toxic is Euphorbia hirta?
We examined the effects of E. hirta’s acute toxicity on behavior, organ body weight index, and the histology of the liver, spleen, lung, heart, and kidney in mice and A. salina in the current study. It has been stated that the brine shrimp (A. salina) cytotoxicity assay is an effective, affordable, and reasonably quick approach to detect harmful chemicals, requiring just small amounts of material, i.e., 20 mg. [13,16] The number of chemicals that can be evaluated is greatly constrained by the tedious process of using higher animals to calculate mortality. [17] The brine shrimp cytotoxicity assay is widely regarded as an easy approach for determining early levels of toxicity. It has been used to test dental materials for cytotoxicity and to detect heavy metals, cyanobacteria toxins, pesticides, food additives, plant extracts, and fungus toxins. [22,23]
The term “adverse change(s) occurring immediately or a short time following a single or short period of exposure to a substance or substances” or “adverse effects occurring within a short time of administration of a single dose of a substance or multiple doses given within 24 h” is commonly used to describe acute toxicity. And an adverse effect is any circumstance that results in a functional impairment and/or biochemical lesions that may have an impact on an animal’s performance as a whole or that reduce an organ’s capacity to respond to new challenges. [21] As a result, a substance is considered to be orally and acutely poisonous if it enters the body through the mouth for a brief period of time and has any negative effects with little to no delay. According to some claims, an acute toxicity test can reveal more details about the biologic characteristics of a chemical molecule than any other test when carried out correctly and constantly monitored. [28]
Twelve Swiss albino mice of both sexes were used in this investigation of acute oral toxicity to examine the effects of the methanol crude extract of E. hirta leaves on toxicity. For regulatory objectives, both sexes were utilized. According to studies, mice are a better predictor of a human acute fatal dose than rats, hence mice were chosen in this study. [14] To prevent food and other compounds in the mice’s digestive tracts from influencing the reaction(s) of the extract ingredients, the mice were fasted before receiving the dose of crude extract, which was given orally. When researching acute toxicity, the oral route of administration is typically the most practical and popular. It is less expensive and causes the animal no pain. [14] Therefore, there is no need to administer anesthetic during the extract. On the other hand, the test animals received treatment in a manner similar to that of traditional healers. As a result, any findings in mice would be simple to extrapolate to what may be anticipated in humans. Every procedure was carried out in accordance with the relevant OECD recommendation. [12]
E. hirta has a lengthy history of folkloristic use in practically every region of the world to treat a variety of illnesses. The decoction of flowering and fruiting plants is used to treat respiratory tract infections, asthma, chronic bronchitis, cough, pulmonary problems, and to get rid of worms in the gut in addition to other conditions. To stimulate lactation, nursing moms are prescribed a leaf infusion. [29] E. hirta is thought to be nontoxic because it is widely known that it is used to treat a number of human ailments and because there have been no prior reports of any adverse effects of the plant. Therefore, a very high dosage level of 5000 mg/kg of crude extract was given to the examined mice in this limit dose oral acute toxicity test. [12]
In this investigation, the treated mice showed a one-third mortality rate. Males responded to the extract more strongly. The fact that this study only revealed less than 50% of deaths suggests that the LD50 is higher than 5000 mg/kg. According to the Organization for Economic Co-operation and Development’s recommendations for chemical labeling and classification of acute systemic toxicity based on oral LD50 values: [12] Very toxic ( 5 mg/kg body weight), toxic (> 5 50 mg/kg), harmful (> 50 500 mg/kg), and unlabeled (> 500 2000 mg/kg) are the four levels of toxicity. E. hirta methanol leaves extract has a low LD50 of more than 5000 mg/kg, which indicates that it is safe. However, the deadly impact discovered in this test suggested that the methanol crude extract of E. hirta, when administered orally at 5g/kg body weight, showed low toxicity. However, given that we used a very high dose of the crude extract—300 g crude extract/60 kg body weight, or, to put it another way, a plateful of the extract—which is much higher than what is typically advised to treat specific ailments—the current study’s findings are consistent with the widespread use of this plant as traditional medicine. In contrast, prior research found that the antispasmodic component of the plant’s aqueous extract was hazardous to mice but not the alcoholic extract. [29] This suggests that the toxicity of plants may be caused by some harmful ingredient that can only be removed in water. As a result, methanolic extract is found to be more active and less hazardous than water extract when compared to earlier investigations.
The liver, kidneys, lungs, spleen, and heart absolute (g) and relative weights (percent) between the treated and control groups remained normal, demonstrating that the plant extract was nontoxic in these crucial organs. An essential marker of physiologic and pathological conditions in both humans and animals is organ weight. The relative organ weight is crucial for determining whether or not the organ was damaged. [32] The principal organs impacted by the metabolic reactions brought on by toxicants are the heart, liver, kidney, spleen, and lungs. [33] For recognized nephrotoxicants, the absolute organ weight has also been demonstrated to be a relatively sensitive index of nephrotoxicity. Increased kidney weight, either relative or absolute, is a sign of nephrotoxicity. [34] According to this indicator, the kidneys and other organs were not adversely affected by the methanol leaf extract of E. hirta since their absolute and relative weights did not differ substantially from control values.
Since many members of the spurge family, which these plants are a part of, are dangerous to both humans and animals, the low LC50 values discovered from the roots and flowers of the E. hirta plant against A. salina may support this argument. Toxic chemicals found in these plant sections are thought to be the cause of this hazardous quality. Because of this, care must be taken when using this plant, and more research is required to identify and characterize the hazardous chemicals. On the other hand, it has already been demonstrated that the A. salina bioassay is a reliable measure of anticancer activity. The plant extract is said to have a wide range of bioactive chemicals and could contain molecules with cytotoxic effects. Therefore, it is advised that extracts poisonous to A. salina be evaluated for toxicity against human tumor cell lines.
