Summarized Description: Erva Tostao, also known by its genus name, "Boerhavia," is a member of the Four O'Clock family, with very wide geographic distribution. This has probably contributed to its confused taxonomy: B. diffusa, B. hirsuta, B. repens, all refer to the very same plant, and there's a half dozen other species names for it, as well. It has too many common names to list then all herein.

Uses & Protocols
The most common herbal application of Erva, and this is true in Africa and South American herbal traditions as well as ayurveda, is in the treatment of liver problems, including jaundice and hepatitis; gallbladder pains / stones; and to expel worms. However, its range of medicinal activity that the properties and indications below should be carefully reviewed.
Dosage: Two capsules, twice a day, or as otherwise directed by your health care practitioner.

Warnings & Contraindications
Do not take Erva if you're on hypotensive, cardiodepressant, or barbituate drugs. Those with heart problems stemming from low blood pressure or heart failure should similarly not take this herb. Erva may interfere with prescription diuretics and can potentiate cardiac depressant medications, prescription diuretics, alpha-adrenergic, and ACE-inhibitor medications for high blood pressure.

Recent Studies on Erva
Sourced from PubMed

Disclaimer: The following citations provide findings on the properties of Erva and offer insights into prospective areas of future research. These findings should not be inferred to provide the basis of medicinal claims, nor should they be relied upon by the public, as such. Readers who want full access to the PubMed database are encouraged to register with NCBI.
As of Jan. 2017, there were 256 citations on PubMed for Erva. Below we list a few of the more notable:
  • Ethnomedicinal uses, phytochemistry and pharmacological properties of the genus Boerhavia. (2016)
  • Antileishmanial efficacy of Boerhaavia diffusa L. and Ocimum sanctum L. against experimental visceral leishmaniasis. (2015) [ABSTRACT: The chemotherapy of visceral leishmaniasis (VL) has several limitations including resistance and toxicity of the existing drugs. Down regulation of immune system further aggravates the problems. To combat this situation we evaluated the leishmanicidal efficacy of Boerhaavia diffusa and Ocimum sanctum through oral route in L. donovani infection in BALB/c mice. Results have demonstrated maximum clearance of the parasites from infected animals treated with combination of B. diffusa and O. sanctum (@ 100 and 400 mg/kg body wt., respectively 5 days) as depicted through Leishman Donovan Units in liver. Up-regulation of cell-mediated immunity was also observed in animals of this group as heightened delayed type hypersensitivity responses and increased IgG2a levels were observed. Moreover, increased levels of SGOT, SGPT, serum urea, blood urea nitrogen and serum creatinine were brought down to normal levels. Since VL is associated immunosuppression, the above treatment is a good option as it helps in the up-regulation of Th1 responses and reduction in parasite load in L. donovani infected mice. These findings suggest a new option for antileishmanial chemotherapy at lower cost and nil toxicity.]
