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.
How is Euphorbia used?
An herb is euphorbia. Medicine is made from the portions of the plant that are grown above ground.
Breathing diseases like asthma, bronchitis, and chest congestion are treated with euphorbia. It is also used to treat tumors, hay fever, throat spasms, and nasal and throat mucus. Some take it to make themselves throw up.
It is additionally employed in India to treat worms, dysentery, gonorrhea, and digestive issues.
How is tea made from Euphorbia hirta made?
100 grams of the fresh, whole plant (including roots) are cleaned and cooked in 500 ml of water for 15 minutes to make tawa-tawa tea. The decoction is given to the patient after chilling and paper-filtration, one glass per hour, till the fever breaks.
What area of the Euphorbia hirta plant is utilized medicinally?
A herb is called Euphorbia hirta. Medicine is made from the portions of the plant that are grown above ground.
There is no reliable scientific evidence to support the use of Euphorbia hirta for the treatment of respiratory disorders, dengue fever, digestive issues, severe diarrhea (dysentery), and many other illnesses.
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.
How often should I consume tawa-tawa?
Standardized tawa-tawa extract should be taken six times day, evenly divided into three doses, 15 minutes before each meal, for adults weighing 50 to 100 kg (2 capsules at 3 times per day). Maintain a dosage of 1 capsule every 10 kg for lesser body weights, to be taken evenly 3 times day. If desired, the capsule’s contents can be dissolved in milk or water. Consumption is continued for three to five days until the platelet count returns to normal. Tawa-tawa is not meant to be consumed as a prophylactic or preventative treatment for dengue. Tawa-tawa is instead used to hasten the healing process after a dengue infection. Given that tawa-tawa has a modest diuretic effect, it’s crucial to take the capsules with a full glass of water.
Yes, patients are highly urged to seek appropriate hospital treatment in order to monitor their platelet count and other crucial blood parameters. To assess the infection’s severity, these tests are crucial. Because dengue leads to plasma leakage, it’s crucial to keep hydrated. Dengue Shock Syndrome, which can be lethal, can result from extreme dehydration.
