General Description

Cumanda is an herbal extract made from the bark of the Campsiandra Angustifolia tree, found in South America. It has been used by indigenous groups in that region for hundreds of years. Cumanda is very effective in treating the Borrelia burgdorferi bacteria and practitioners are now using it in conjunction with Samento to treat Lyme Borreliosis with co-infections. Lyme Borreliosis has been linked to hundreds of medical conditions. Many researchers and physicians believe that Lyme Borreliosis may be a factor in most chronic conditions. One of the most impressive benefits of Cumanda is its antifungal action. Physicians report that it is effective in treating many difficult to treat fungi including Mycosis fungoides, Candida krusei, Candida albicans and Aspergillus niger, to name a few.

in vivo – Anti-inflammatory

Establishment of the Potential Anti-inflammatory Effect of the product known as Cumanda.  The study demonstrated that Cumanda had a marked anti-inflammatory effect and was 99% as effective as Feldene, a non-steroidal anti-inflammatory drug also known as PIROXICAM. University of Guayaquil, Department of Chemical Sciences, Guayaquil, Ecuador (2005).

At the University of Guayaquil, Ecuador, Cumanda produced an anti-inflammatory effect 112% as strong as Celebrexas an anti-inflammatory. Full Article


‍An acute oral toxicity study was conducted by the University of Guayaquil, Ecuador concluding that Cumanda did not produce toxic effects, thus the product is considered practically innocuous for humans when administered in the acute form. Therefore; studies of acute toxicity at higher doses in humans are not necessary.  Full Article

Lyme Disease: A Hidden Epidemic

Many people think of Lyme disease as a simple illness caused by the bite of an infected tick.Though a bite may be a triggering event, this perspective is simplistic and does not take into consideration the numerous issues that both the patient and doctor must consider and treat in order to attain the best possible outcomes. Furthermore, medical literature suggests that Lyme disease is a complex illness which may be transmitted by mosquito bites, blood transfusions, sexual intercourse and many other ways.
