Tawa-tawa is usually abundant throughout the Philippines in waste places and open grasslands.
The plant is an annual hairy herb, usually much-branched from the base. These branches are simple or forked, ascending or spreading up to 40 centimeters long and often reddish or purplish. The leaves are opposite, distichous, oblong-elliptic to oblong-lanceolate, 1 to 2.5 centimeters long, toothed at the margin, and usually botched with purple in the middle. The plant deserves special attention because of its medicinal properties. Local tradition credits that this plant can help patients stricken with dengue fever. While it does not fight with the virus, it promotes the development of blood platelets and softens the effect of the viruses which attack the blood. However the department of health advises the public not to be much dependent on the said herbal medicine, despite its proven efficacy. This study was conducted to elucidate the structure, antimicrobial and…...

Ninety-five percent of healthy people will have platelet counts in this range. Some will have statistically abnormal platelet counts while having no demonstrable abnormality. However, if it is either very low or very high, the likelihood of an abnormality being present is higher. Some diseases or disorders in the platelet count in the blood are the Thrombocytosis where the presence of platelets in blood is high and Thrombocytopenia where platelets count in blood is low. In this case, a new way to develop platelets is needed.

Doh Now Taking 'Tawa-Tawa' Seriously

...DOH now taking 'tawa-tawa' seriously in fight vs dengue CLARK FREEPORT, Pampanga, Philippines – A weed known as tawa-tawa has become a serious matter for the Department of Health (DOH), which is now considering the proposal of herbalist and former health secretary Jaime Galvez Tan to fund a research on the plant as possible panacea to the fatal bleeding among dengue victims. Health Assistant Secretary Elmer Punzalan said here yesterday that the Philippine Traditional and Alternative Health Care (PTAHC), an agency under the DOH, is now coordinating with Tan on the latter’s proposal for a P20-million research fund to finally establish whether tawa-tawa arrests bleeding, which is the main reason why dengue victims die. The weed is said to prevent hemorrhaging by normalizing platelet count in the blood. According to latest DOH reports, dengue cases in the country this year have already breached the 90,000 mark. Punzalan bared this in a press conference during the launch here of the two-day Generic Medicine Expo for Luzon, a joint project of the DOH and the National Center for Pharmaceutical Access and Management, in partnership with SM Prime Holdings Inc. The expo aims “to boost and sustain advocacy on quality affordable medicine through generics’ use and its role and importance in improving wellness and compliance of patients to treatment regimens.” Earlier, Dr. Eric Tayag, chief epidemiologist of the DOH, dismissed tawa-tawa as cure for dengue as not enough research on......

...plant , Tawa-tawa had a report that it can cure dengue fever. According to the article from Dr. Willie T. Ong entitled “Treatment for Dengue” which was published on The Philippine STAR, there is no specific drug to kill the dengue virus. However, doctors can employ various supportive measures to strengthen the body so that it can recover from the disease. Here's how we do it :  1. Patients are encouraged to drink lots of water to keep the body's water at an optimum level. If needed, doctors give dextrose fluid to prevent dehydration.  2. Monitoring of blood count. Doctors check the hematocrit and platelet count regularly to see if there is a need to transfuse blood components.  3. Consider giving medicines to prevent ulcer, since bleeding is a possibility.  4. Encourage the patient to eat regularly, specifically soft, easily digestible foods. Patients are advised to avoid eating dark colored foods, because we need to monitor the stool's color. (Black stools means blood for doctors.)  5. Tawa Tawa plant might help.  In the Philippines, many patients are using Tawa Tawa plants to treat dengue. The Department of Health is still studying the effectiveness of this plant, and has raised concern over the possibility of toxicity with over dosage. However, doctors would usually allow patients to drink it if you ask their permission first.  Here's how to prepare Tawa Tawa:  (1) Take 5 whole Tawa Tawa plants;  (2) Cut off the roots, then wash and clean;  (3) Boil Tawa Tawa......

...DoH sees hope in 'tawa-tawa' as dengue cure By JENNY F. MANONGDO August 26, 2011, 7:14pm MANILA, Philippines — Department of Health (DoH) Secretary Enrique T. Ona announced Friday that preliminary laboratory testing of the plant “tawa-tawa” (scientific name: euphorbia hirta) suggests that it may have “some effect” in treating dengue patients. While Ona said these tests remain inconclusive, the Department of Science and Technology (DoST) will continue its research on the active ingredient in the plant that appears to be effective in beating the virus. “It looks like they (DoST scientists) have already isolated the active ingredient in the plant and it appears that it really has some effect,” Ona told the press during a forum organized by the Philippine Information Agency (PIA) in Quezon City. Believers in herbal medication have long claimed that tawa-tawa is effective in curing dengue patients but there had been no formal scientific research to confirm it. Dengue survivors who claim they were cured by the plant professed that their blood platelets count increased after drinking water from the boiled plant. Ona said it is better to have a research-backed method of using the plant rather than just using it as one would use any tea – boiling the leaves and drinking the juice. “It is scientific to find the component, the active ingredients... hopefully, they will be able to isolate it and come up with a concentrated form,” he said. Ona said he has not......

Dengue is found in tropical and sub-tropical regions around the world, predominantly in urban and semi-urban areas. Dengue Hemorrhagic Fever (DHF), a potentially lethal complication, was first recognized in the 1950’s during dengue epidemics in the Philippines and Thailand. DHF affects most Asian countries and has become a leading cause of hospitalization and death among children. There are four distinct, but closely related, viruses that cause dengue. Recovery from infection by one provides lifelong immunity against that virus but confers only partial and transient protection against subsequent infection by the other three viruses. Sequential infection increases the risk of developing DHF. There is no specific medicine or antibiotic to treat DHF. For typical dengue, the immediate concern is the relief of symptoms. Adequate fluid intake for proper body hydration and rest is important. All else will depend on the person’s immune system. However, since the Philippines is abundant with herbal medicines, the Tawa Tawa is being touted as an alternative cure to DHF. The Tawa Tawa is described as......

The Efficacy of Tawa-Tawa Plant (Euphorbia Hirta) Treated with Riboflavin in the Development of Blood Platelets

...The Efficacy of Tawa-Tawa Plant (Euphorbia Hirta) Treated with Riboflavin in the Development of Blood Platelets Chapter I INTRODUCTION In modern medicines, plants occupy a very important place as the raw material for some important drugs. Synthetic drugs are effective in controlling different diseases but these synthetic drugs are out of reach of millions of people. It is estimated that around 70,000 plant species have been used for medicinal purposes. The herbs provide the starting material for the synthesis of conventional drugs. (Kumal & Malhotra, 2010) Medicinal plants have curative actions due to the presence of complex chemical constituents. Today, lots of health problems are escalating. One of these is coagulation problems. A normal platelet count in a healthy individual is between 150,000 and 450,000 per μl (microlitre) of blood (150–450 x 109/L). Ninety-five percent of healthy people will have platelet counts in this range. Some will have statistically abnormal platelet counts while having no demonstrable abnormality. However, if it is either very low or very high, the likelihood of an abnormality being present is higher. Some diseases or disorders in the platelet count in the blood are the Thrombocytosis where the presence of platelets in blood is high and Thrombocytopenia where platelets count in blood is low.
