The only active plant against microbes five was the Lippia palmeri, a relative of the Luisa herb. The Larrea tridentata, known in the U.S. as a splash or creosote, was very active against streptococcus, bacillus and staphylococcus. Guatemalan researchers have also studied the medicinal herbs traditionally used against bacteria. Added 68 plants for the treatment of the respiratory infections to cultivation of major respiratory infectious agents.

This article includes a list of plants according to family, local name, used parts and bibliographical references on the use of each one. The authors started with a list of 234 medicinal herbs, from ethnobotanical research, 149 of whom were originating in the American continent. Unfortunately, only 37 medicinal herbs with three microorganisms were tested, but the overall results were encouraging. 40% Of herbal medicines were active against at least one bacterium. A plant, the fruit of the Physalis philadelphica, used for bronchitis, colds, and sore throat, was active against the three bacteria. Other promising plant extracts showed high activity against two bacteria, including Eucalyptus globulus, Salvia officinalis, Lippia alba and l.

dulcis. Therefore, there is now a preliminary scientific evidence of the popular use of some of the plants that antibacterial activity is assumed. The authors note that studies additional will allow the scientific community recommend its use as an accessible and safe alternative to synthetic antibiotics. More antivirals Utah scientists reported promising antiviral activity of plants used in traditional medicine in Panama this year. Evaluated plants are little known in the United States, but the study confirms the rational justification of their employment in the indigenous medicine. The most encouraging results occurred with the Ouratea lucens and the cipo Trichilia. Another species of the first genus, the o. angustifolia, has been used as a tonic and stomachic, while that the T. havanensis is used for the treatment of malaria. The Ouratea lucens and the cipo Trichilia proved to have greater activity against viruses herpes simplex 1 and 2 (HSV 1 and HSV) and vesicular stomatitis (VEV). The findings have particular relevance because they go beyond providing indications on antivirals for use potentially important for modern medicine. Also They point out plants related to the species used in traditional medicine that may be better alternatives than those used. These plants have exceeded levels that are usually considered significant to the antiviral drugs, reducing infection by VEV even at a 99.9%. The doses used in invitro tests were well below levels that could harm normal cells (human diploid cell). Furthermore, as that were more toxic to human tumor cells for normal, the authors highlight their potential roles as anti-tumour agents should be investigated more extensively. Together, these data suggest that examined Panamanian plants extracts contain components that can be used effectively as antiviral or antitumor agents.
