Factors and Practices Associated with Self-Medicating Children among Mexican Parents.

BACKGROUND: Pediatric self-medication is based on the subjective interpretation of symptoms in children by the mother or an adult, the decision to self-medicate is made by a third party. The objective of this work is to provide information on the factors and practices associated with the self-medication of children among parents in Mexico. METHODS: A cross-sectional and descriptive study was conducted between June 2020 and December 2021 on Mexican parents with children under 12 years of age. Online questionnaires were completed with sections on sociodemographic characteristics, use of medicines or medicinal plants and their treated symptoms, sources of collection, and their recommendation. RESULTS: A total of 9905 online surveys were completed with representation from the 32 states of Mexico, and the prevalence of self-medication was 49.6% (n = 4908). Associated factors were age, having two or more children, children with chronic illnesses, medium educational level, unemployment or employment unrelated to health, medium and high socioeconomic level, and lack of medical security. Respondents self-medicated their children on the recommendation of a family member or friend (55.8%), and own initiative (28%). The most used medication was VapoRub (61.3%), followed by paracetamol (56.9%) and chamomile (33.1%), and the most prevalent symptoms were flu/flow (47.7%) followed by cough (34.2%). The main reasons were perceiving symptoms as not serious (69.9%) and reusing medications (51.9%). CONCLUSIONS: There is a high prevalence of self-medication in children in Mexico, mainly associated with children with chronic diseases and families with three or more children.

Self-medication practice in pregnant women from central Mexico.

Self-medication during pregnancy represents a serious threat for mother and child health. The objective of this study was to evaluate the prevalence and the factors associated with self-medication among Mexican women living in the central region of Mexico. This is a descriptive interview-study of 1798 pregnant women or women who were pregnant no more than 3 years ago, when the interview was carried out. Data analysis was carried out with chi-square analysis and odds ratio. The prevalence of self-medication (allopathic drugs, medicinal plants, and other products, including vitamins, food supplements, among others) was 21.9%. The factors associated (p < 0.05) with self-medication were: higher education (college and postgraduate), smoking, and consumption of alcohol. Smoking was the strongest factor (OR: 2.536; 1.46-4.42) associated to self-medication during pregnancy, followed by consumption of alcohol (OR: 2.06; 1.38-3.08), and higher education (OR: 1.607; 1.18-2.19). Medicinal plant consumption was associated with nausea, constipation, migraine, and cold (p < 0.05), whereas he self-medication of allopathy was associated with gastritis and migraine (p < 0.05). Self-medication was influenced mainly by a relative or friend, who recommended the use of herbal medicine/allopathic medication. Two of the most common medicinal plants (arnica and ruda) here informed are reported to induce abortion or toxicity during pregnancy. The findings showed that self-medication (medicinal plants and allopathic medication) is a common practice among pregnant women from central Mexico. Adequate counselling of pregnant women by healthcare professionals about the potential risks of self-medication with herbal medicine and allopathic drugs during pregnancy is strongly warranted.

Chemical characterization, pharmacological effects, and toxicity of an ethanol extract of Celtis pallida Torr. (Cannabaceae) aerial parts.

ETHNOPHARMACOLOGICAL RELEVANCE: Celtis pallida Torr (Cannabaceae) is employed as a folk medicine for the treatment of inflammation, pain, skin infections, and diarrhea, among other diseases. AIM OF THE STUDY: The purpose of this work was to assess the chemical composition, the in vitro and in vivo toxicity, the antimicrobial, anti-inflammatory, antidiarrheal, antinociceptive, locomotor, and sedative effects of an ethanolic extract obtained from Celtis pallida aerial parts (CPE). MATERIALS AND METHODS: The composition of CPE was carried out by GC-MS. The in vitro and in vivo toxic activity of CPE was estimated with the comet assay (10-1000 µg/ml) for 5 h in peripheral blood mononuclear cells, and the acute toxicity test (500-5000 mg/kg p.o.), for 14 days, respectively. The antimicrobial effect of CPE was evaluated using the minimum inhibitory concentration (MIC) assay, whereas the antidiarrheal activity (10-200 mg/kg p.o.) was calculated using the castor oil test. The antinociceptive effects of CPE (50-200 mg/kg p.o.) were estimated with the acetic acid and formalin tests, as well as the hot plate test. The sedative and locomotor activities of CPE (50-200 mg/kg p.o.) were assessed with the pentobarbital-induced sleeping time test and the rotarod test, respectively. RESULTS: The main compound found in CPE was the triterpene ursolic acid (22% of the extract). CPE at concentrations of 100 µg/ml or higher induced genotoxicity in vitro and showed low in vivo toxicity (LD50 > 5000 mg/kg p.o.). Additionally, CPE lacked (MIC > 400 µg/ml) antimicrobial activity but exerts antinociceptive (ED50 = 12.5 ±â€¯1.5 mg/kg) and antidiarrheal effects (ED50 = 2.8 mg/kg), without inducing sedative effects or altering the locomotor activity. The antinociceptive activity of CPE suggests the participation of adrenoceptors, as well as the nitric oxide/cyclic guanosine monophosphate (cGMP) pathway. CONCLUSION: C. pallida exerts its antinociceptive effects probably mediated by the nitric oxide/cyclic guanosine monophosphate (cGMP) pathway.

Medicinal Plants from North and Central America and the Caribbean Considered Toxic for Humans: The Other Side of the Coin.

The consumption of medicinal plants has notably increased over the past two decades. People consider herbal products as safe because of their natural origin, without taking into consideration whether these plants contain a toxic principle. This represents a serious health problem. A bibliographic search was carried out using published scientific material on native plants from Mexico, Central America, and the Caribbean, which describe the ethnobotanical and toxicological information of medicinal plants empirically considered to be toxic. A total of 216 medicinal plants belonging to 77 families have been reported as toxic. Of these plants, 76 had been studied, and 140 plants lacked studies regarding their toxicological effects. The toxicity of 16 plants species has been reported in clinical cases, particularly in children. From these plants, deaths have been reported with the consumption of Chenopodium ambrosioides, Argemone mexicana, and Thevetia peruviana. In most of the cases, the principle of the plant responsible for the toxicity is unknown. There is limited information about the toxicity of medicinal plants used in Mexico, Central America, and the Caribbean. More toxicological studies are necessary to contribute information about the safe use of the medicinal plants cited in this review.

Use of medicinal plants by health professionals in Mexico.

ETHNOPHARMACOLOGICAL RELEVANCE: The use of medicinal plants in Mexico has been documented since pre-Hispanic times. Nevertheless, the level of use of medicinal plants by health professionals in Mexico remains to be explored. AIM OF THE STUDY: To evaluate the use, acceptance and prescription of medicinal plants by health professionals in 9 of the states of Mexico. MATERIALS AND METHODS: Direct and indirect interviews, regarding the use and acceptance of medicinal plants, with health professionals (n=1614), including nurses, physicians, pharmacists, and odontologists from nine states in Mexico were performed from January 2015 to July 2016. The interviews were analyzed with the factor the informant consensus (FIC). RESULTS: The information obtained indicated that 46% of those interviewed feel patients should not use medicinal plants as an alternative therapy. Moreover, 54% of health professionals, and 49% of the physicians have used medicinal plants as an alternative therapy for several diseases. Twenty eight percent of health professionals, and 26% of the physicians, have recommended or prescribed medicinal plants to their patients, whereas 73% of health professionals were in agreement with receiving academic information regarding the use and prescription of medicinal plants. A total of 77 plant species used for medicinal purposes, belonging to 40 botanical families were reported by the interviewed. The results of the FIC showed that the categories of diseases of the digestive system (FIC=0.901) and diseases of the respiratory system (FIC=0.898) had the greatest agreement. CONCLUSIONS: This study shows that medicinal plants are used for primary health care in Mexico by health professionals.

Zootherapeutic practices in Aquismón, San Luis Potosí, México.

ETHNOPHARMACOLOGICAL IMPORTANCE: Animal derived products have been a source of medicinal compounds since ancient times. This work documents the use of animal species in traditional medicine in the municipality of Aquismón, San Luis Potosí, México. MATERIALS AND METHODS: Direct interviews were performed with inhabitants from Aquismón. The interviews were analyzed with two quantitative tools: (a) the informant consensus (ICF) that estimates the level of agreement about which animals may be used for each category and (b) the relative importance (RI) that determines the extent of potential utilization of each species. RESULTS: A total of 24 animal species used for medicinal purposes, belonging to 22 families and 4 taxonomic categories, were reported by interviewees. Nine medicinal species had not been reported in scientific literature. The results of the IFC showed that diseases of the respiratory systems had the greatest agreement. The most versatile species according to their RI are Crotalus atrox and Mephitis macroura. CONCLUSION: Further studies with medicinal fauna from Aquismón are required for the experimental validation of their traditional uses, especially with Mephitis macroura and Crotalus atrox.
