It has culinary and medicinal benefits. CAP activates its receptor, transient receptor potential vanilloid subfamily 1 (TRPV1), which is expressed in the sensory and motor neurons, adipocytes, liver, vascular smooth muscle cells, neuromuscular junction, skeletal muscle, heart and brain. The specificity of CAP to activate TRPV1 is the fundamental mechanism for its medicinal benefits to treat pain, obesity, hypertension, and other diseases. Preclinical data from rodent model of high fat diet-induced obesity collectively suggest that CAP exerts its effects by activating TRPV1 signaling pathway, which stimulates thermogenic mechanisms in the white and brown adipose tissues to induce browning of white adipose tissues and brown adipose tissue thermogenesis. This leads to enhancement of metabolic activity and thermogenesis to counter obesity. Although CAP and its pungent and nonpungent analogs are used in human clinical studies, their effects on satiety and energy expenditure have been the highlights of such studies. The precise mechanism of action of CAP has not been evaluated in humans. This article summarizes these data and suggests that long-term safety and tolerance studies are important for advancing CAP to treat human obesity.","PeriodicalId":435706,"journal":{"name":"Capsaicin and its Human Therapeutic Development","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131395412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pungent Chili varieties are grown for their food value, health- promoting properties and as a source of capsaicinoids that have a variety of medicinal uses. Accessions of the cultivated species ( Capsicum annuum , C. baccatum , C. chinense , C. frutescens , and C. pubescens ) have not all been analyzed for their capsaicinoids content. Identifying Capsicum species and accessions (genotypes) within species with high levels of antioxidants and bioactive compounds (capsaicin, dihydrocapsaicin, vitamin C, vita min E, phenols, and β-carotene) that contribute to human disease therapy is the focus of this investigation. The main objectives of this chapter are to compile an overview of most recent achievements of the pharmacological properties of hot pepper compounds and provide a rationale for their use as analgesics and to present an evidence that supports the use of capsaicinoids in the treatment of neuropathic pain and other top leading death of worldwide human diseases.","PeriodicalId":435706,"journal":{"name":"Capsaicin and its Human Therapeutic Development","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114150515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With 32 known species, five of them domesticated, they provide unique chemical profiles, when consumed by humans. Capsaicinoids, the spicy compounds, are alkaloids used to deter herbivory in the wild, offering protection to the chile pepper fruit seeds. Among the 22 known capsaicinoid structures, capsaicin and dihydrocapsaicin are normally the most abundant. In humans, capsaicin binds to nociceptor TRPV1 that generates a heat sensation. Capsaicin also miti - gates inflammation responses in the digestive tract and has the potential to aid in nutri ent absorption. Distinct heat profiles were recently described for the five domesticated Capsicum species showing a difference in heat sensations specific to species and pod type. Due to the many capsaicinoid structures, we explore the implications and opportunities of having a diverse array of heat profiles in genetically diverse Capsicum species.","PeriodicalId":435706,"journal":{"name":"Capsaicin and its Human Therapeutic Development","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133120101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Capsaicin therapeutic effect is dependent on various factors like the concentration of capsaicin, delivery to different cell types, route of admin -istration, and their metabolism. Improvement in the delivery of capsaicin will increase its therapeutic efficacy. Recent advancement in various technologies had provided numer ous strategies to deliver capsaicin.

One of the most promising treatments developed in recent years is the capsaicin 8% patch. But given the high cost of treatment, the patch should be applied only to those most likely to benefit from improve- ment. There have been several studies that have tried to look for predictors of treatment response. Three of them found correlation with pain and response to treatment. The pre- dictors found were: baseline pain scores, variability of pain prior to treatment, pain response for lidocaine pretreatment, and time with preexisting pain. Four studies found that sensory abnormalities used for prediction of response to treatment seems to be useful as well. Though the correct sensory sensations are not clear there seems to be a tendency for the burning or heat-pain sensations and the pressure-pain sensations to be taken into account. From this findings, it seems that patients with exclusively peripheral damage and with no central plastic changes are the most suitable for treatment. There must be some more research to be done, where a combination of the predictors already found could give a very high predictability of treatment response, lowering de NNT to almost 1.","PeriodicalId":435706,"journal":{"name":"Capsaicin and its Human Therapeutic Development","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114888464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
