The aim of this open-label, fixed-sequence study was to investigate the potential of Echinacea purpurea, a commonly used botanical supplement, to interact with the boosted protease inhibitor darunavir-ritonavir. Fifteen HIV-infected patients receiving antiretroviral therapy including darunavir-ritonavir (600/100 mg twice daily) for at least 4 weeks were included. E. purpurea root extract capsul...
The effect of gamma and microwave irradiation on antioxidant and antimicrobial activities of Cinnamomum zeylanicum and Echinacea purpurea were investigated. In this study, all samples were exposed to gamma irradiation at doses 10, 15, 20 and 25 kGy and microwave irradiation at power of 100, 180 and 300 W for 5 min. In order to undergo the sequence expriments, the hydroalcoholic (EtOH 50%) extra...
BACKGROUND Acute disseminated encephalomyelitis (ADEM) is a rare demyelinating disease of the central nervous system, commonly attributed to infections or vaccinations. Toxic or allergenic compounds can also trigger a response in the immune system and may cause demyelination. We present a case with ADEM after using oral herbal medications. CASE REPORT A 25 year-old male developed bilateral ce...
Background & Aim: Hydroxycinnamic acids are one of the most important bioactive substances of Echinacea drugs. These compounds possess immuno-enhancing activity and thus, total hydroxycinnamic acids are mostly used as the main criterion for quality control of Echinacea purpurea and its drugs. Hence, the quality control of Echinacea requires to develo...
The timing of herbivory can be an important factor in the strength and direction of plant response to herbivore damage. To determine the effect of vole herbivory timing within a growing season on tallgrass prairie forbs, we used individual plant enclosures to limit vole access to three species, Desmanthus illinoensis, Echinacea purpurea, and Heliopsis helianthoides, in an experimental restorati...
Aging is a multifactorial process that leads to loss of function and the inability to adequately respond to external stress. There has been a global trend toward the use of natural phytochemicals present in natural sources as antioxidants and functional foods. The herb, Echinacea, is one of the most popular herbal medicines and has become one of the top-selling herbs of all time with billions o...
Echinacea is one of the most commonly used herbal products, but controversy exists about its benefit in the prevention and treatment of the common cold. Thus, we did a meta-analysis evaluating the effect of echinacea on the incidence and duration of the common cold. 14 unique studies were included in the meta-analysis. Incidence of the common cold was reported as an odds ratio (OR) with 95% CI,...
Commercial Oregano oils with high concentrations of carvacrol have been vigorously promoted as antiviral agents effective against colds and ‘flu, including the pandemic H1N1 virus. However there seems to be no evidence to support these claims. Furthermore, since carvacrol itself is known to be toxic, so-called “carrier oils”, such as olive oil, have been included in formulations to ameliorate t...
Echinacea has been viewed as an immunoenhancing herb since it became commercially available several years ago. Indeed, its medicinal significance is responsible for billions of dollars in worldwide sales annually. Unfortunately, most of the 'evidence' for the purported medicinal efficacy of Echinacea has been anecdotal and, moreover, to this day, there is no formal proof on how to achieve the b...
