Analysis on the current quality standards of Chinese materia Medica used in COVID-19 prevention and treatment.

PURPOSE: Traditional Chinese medicine (TCM) has fully engaged and played an essential role in the prevention and treatment of Coronavirus Disease 2019 (COVID-19). This study compares relevant standards on high-frequent Chinese Materia Medicia (CMM) used in this pandemic aiming at reaching a global consensus and ensuring the use of Chinese medicines safely. METHODS: 141 representative Chinese formulas and Chinese Patent Medicines from the National Protocol and the most of Provincial Protocols for controlling COVID-19 in China have been collected to statistical analyze the composition and characteristics of CMM. Among them, the domestic and international standards of 47 varieties with the frequency usage over 10 times were selected to compare their quality requirements in the mainstream pharmacopoeias and international standards. RESULTS: The quality requirements of used CMM for fighting COVID-19 on the terms of overall quality control, marker compounds, and safety indicators showed different patterns in these mainstream pharmacopoeias and international standards. The uniformed and scientific quality standards of CMM were urgently needed to promote global acceptation and trade. CONCLUSIONS: These findings will provide evidence for building unified quality and safety standards that can adapt to the characteristics of CMM and promote international trade, and also will be stated that it is of the highest priority for ISO/TC 249 to formulate high-quality standards that consolidate international consensus to ensure quality and safety of the urgently needed CMM.

Multicenter Clinical Trials Analyzing Efficacy and Safety of Topical Cortex Phellodendri Compound Fluid in Treatment of Diabetic Foot Ulcers.

BACKGROUND The aim of this study was to analyze the clinical application of cortex phellodendri compound fluid (CPCF) in the treatment of diabetic foot ulcers. MATERIAL AND METHODS From January 2012 to December 2015, a total of 720 cases of diabetic foot ulcers (DFU) were randomly assigned into an experimental group (n=540) that was treated by CPCF and a control group (n=180) that was treated by a Kangfuxin solution (KFS). After 4 weeks of treatment, their ulcer area, serum growth factor, clinical total effective rate, and incidence of adverse events were assessed. RESULTS There were 720 patients who completed the trial. The experimental group was superior to the control group in reducing ulcer area, increasing growth factor content, and total effective rate (P<0.05). There was no significant difference in the adverse events rates between the 2 groups. CONCLUSIONS CPCF external treatment of diabetic foot ulcer can promote ulcer healing and increase the concentration of growth factors, and it is safe and reliable.

Toxicological assessment compilation of selected examples of raw materials for homeopathic medicinal products.

The considerable number of homeopathic medicinal products (HMP) on the German market and the staggering breadth of active substances of various origin along with the specific legal requirements of adequate safety principles posed the need to compile data on toxicologically evaluated raw materials. In line with the European regulatory framework, HMP applications must consider appropriate safety standards in analogy to conventional human medicinal products. This review presents an option for a systematic and scientifically substantiated approach for regulatory use. Furthermore, this paper provides a multitude of data for selected raw materials processed in HMP with up to now rather scarce knowledge and, thus, aims at filling data gaps on acceptable amounts per day (AAD). The inclusion of raw materials into the compilation was determined considering the frequencies of their occurrence in HMP in Germany along with the availability of appropriate safety assessments. This safety evaluation compilation represents a practical, fairly comprehensive and systematic set of more than 170 raw materials. It is designed to both effectively support regulatory decision making and to be recognized and exploited by applicants, stakeholders and the scientific community.

Anisocoria Secondary to Anticholinergic Mydriasis from Homeopathic Pink Eye Relief Drops.

A woman, aged 70 years, developed anisocoria after applying homeopathic eye drops (Similasan Pink Eye Relief) to her left eye. Her pupil was dilated for two weeks and did not respond to light or near stimuli for one week. Both 0.1% and 1% pilocarpine failed to constrict her left pupil, and magnetic resonance imaging of her brain did not reveal any abnormality. The eye drops she had used contain belladonna extracts which have a natural atropine component. This case demonstrates the importance, when evaluating a patient presenting with anisocoria, of knowing the chemical ingredients of the homeopathic eye drops, which often are not listed.

Current concepts on integrative safety assessment of active substances of botanical, mineral or chemical origin in homeopathic medicinal products within the European regulatory framework.

For active substances of botanical, mineral or chemical origin processed in homeopathic medicinal products for human use, the adequate safety principles as with other human medicinal products are applied in line with the European regulatory framework. In homeopathy, nonclinical safety assessment is facing a particular challenge because of a multitude and diversity of source materials used and due to rarely available toxicological data. Thus, current concepts applied by the national regulatory authority in Germany (BfArM) on integrative safety assessment of raw materials used in homeopathic medicinal products involve several evaluation approaches like the use of the Lowest Human Recommended Dose (LHRD), toxicological limit values, Threshold of Toxicological Concern (TTC), data from food regulation or the consideration of unavoidable environmental or dietary background exposure. This publication is intended to further develop and clarify the practical use of these assessment routes by exemplary application on selected homeopathic preparations. In conclusion, the different approaches are considered a very useful scientific and simultaneously pragmatic procedure in differentiated risk assessment of homeopathic medicinal products. Overall, this paper aims to increase the visibility of the safety issues in homeopathy and to stimulate scientific discussion of worldwide existing regulatory concepts on homeopathic medicinal products.

Use of natural health products in children: experiences and attitudes of family physicians in Newfoundland and Labrador.

OBJECTIVE: To determine the experiences of family physicians in Newfoundland and Labrador with parents' use of natural health products (NHPs) for their children and to assess physicians' attitudes toward use of NHPs in children. DESIGN: A survey using the Dillman approach. SETTING: Newfoundland and Labrador. PARTICIPANTS: All family physicians in the province. MAIN OUTCOME MEASURES: Physician demographic characteristics; whether physicians inquire about the use of NHPs in children; the degree to which they think patients disclose use of NHPs in children; whether they counsel parents about the potential benefits or harms of NHPs; their own opinions about the usefulness of NHPs; whether they recommend NHPs in children and for what reasons; and the particular NHPs they have seen used in children and for what reasons. RESULTS: A total of 159 (33.1%) family physicians responded; 65.4% were men, 71.7% were Canadian medical graduates, and 46.5% practised in rural areas. Overall, 18.8% of family physicians said they regularly or frequently asked about NHP use; 24.7% counseled patients about potential harms. Only 1.9% of physicians believed NHPs were usually beneficial, but a similarly small number (8.4%) thought they were usually harmful. Most respondents were somewhat neutral; 59.7% said they never recommend NHPs for children, and a further 37.0% said they would only "sometimes" recommend NHPs. CONCLUSION: Most physicians believed that NHPs were probably of little benefit but not likely to be harmful. Most NHPs used were vitamins and minerals. Physicians recognized that NHPs were often used by parents for children, but in general they believed NHPs had little effect on their day-to-day medical practices. Thirty-eight (24.7%) of the 154 physicians had at least once recommended an NHP (including vitamins) for their pediatric patients. Physicians believed that parents did not often disclose use of NHPs for their children, but at the same time physicians generally did not actively inquire.

Acute Fulminant Hepatic Failure in 23-Year-Old Female Taking Homeopathic Remedy.

Homeopathic remedies made primarily from eggshells, and therefore calcium, can be marketed for treatment of back pain and vaginal discharge. We present a case of a 23-year-old otherwise healthy woman who presented with acute liver failure (ALF) ultimately requiring liver transplantation as a result of taking increased doses of a homeopathic product with the primary ingredient of eggshells. Although relatively uncommon compared with medications such as acetaminophen, herbal supplements have been reported to cause drug-induced liver injury (DILI), thought to be primarily due to contaminants. This is the first known report of DILI resulting from a homeopathic product with the primary ingredient of eggshells, and it demonstrates the importance of early ALF recognition and treatment, as well as the importance of practicing caution when using homeopathic supplements.

A series of homeopathic remedies-related severe drug-induced liver injury from South India.

INTRODUCTION: Homeopathic remedies are highly diluted formulations without proven clinical benefits, traditionally believed not to cause adverse events. Nonetheless, published literature reveals severe local and non-liver-related systemic side effects. We present the first series on homeopathy-related severe drug-induced liver injury (DILI) from a single center. METHODS: A retrospective review of records from January 2019 to February 2022 identified 9 patients with liver injury attributed to homeopathic formulations. Competing causes were comprehensively excluded. Chemical analysis was performed on retrieved formulations using triple quadrupole gas chromatography-mass spectrometry and inductively coupled plasma atomic emission spectroscopy. RESULTS: Males predominated with a median age of 54 years. The most typical clinical presentation was acute hepatitis, followed by acute on chronic liver failure. All patients developed jaundice, and ascites were notable in one-third of the patients. Five patients had underlying chronic liver disease. COVID-19 prevention was the most common indication for homeopathic use. Probable DILI was seen in 77.8%, and hepatocellular injury predominated (66.7%). Four (44.4%) patients died (3 with chronic liver disease) at a median follow-up of 194 days. Liver histopathology showed necrosis, portal and lobular neutrophilic inflammation, and eosinophilic infiltration with cholestasis. A total of 29 remedies were consumed between 9 patients, and 15 formulations were analyzed. Toxicology revealed industrial solvents, corticosteroids, antibiotics, sedatives, synthetic opioids, heavy metals, and toxic phyto-compounds, even in 'supposed' ultra-dilute formulations. CONCLUSION: Homeopathic remedies potentially result in severe liver injury, leading to death in those with underlying liver disease. The use of mother tinctures, insufficient dilution, poor manufacturing practices, adulteration and contamination, and the presence of direct hepatotoxic herbals were the reasons for toxicity. Physicians, the public, and patients must realize that Homeopathic drugs are not 'gentle placebos.'

Treating menopausal symptoms with a complex remedy or placebo: a randomized controlled trial.

OBJECTIVE: To evaluate the efficacy and safety of a complex remedy compared with placebo to treat menopausal symptoms. METHODS: A total of 102 peri- and postmenopausal women requiring treatment for menopausal symptoms were randomized to receive a complex anthroposophic remedy prepared in the homeopathic manner (Apis regina tota GL D4, Argentum metallicum D5, Ovaria bovis GL D4), 3 × 10 globuli daily (2 × 12 weeks) and placebo (12 weeks) in different orders of remedy (R) and placebo (P) (1: R/R/P, 2: P/R/R, 3: R/P/R). The primary endpoint was change in climacteric symptoms assessed by the Menopause Rating Scale II (MRS II) after 12 weeks. Secondary endpoints were changes of symptoms and safety throughout the study. RESULTS: Reduction of symptoms after 12 weeks did not differ between remedy and placebo (total score MRS II: -1.4, 95% confidence interval (CI) -2.8 to 0 vs. -2.3, 95% CI -4.4 to -0.3, p = 0.441) and had no clinical relevance (defined as reduction in MRS II ≥ -3.5). Comparison of secondary outcomes at 12 weeks between remedy and placebo or between groups after the 2nd or 3rd period compared to previous periods did not differ. Treatment with remedy for 24 consecutive weeks did not reach clinical relevance either. However, total reduction of symptoms after three periods in Group 1 (R/R/P) (-5.0, 95% CI -7.5 to -2.5) and Group 2 (P/R/R) (-5.9, 95% CI -8.7 to -3.1) reached clinical relevance whereas almost no decrease of symptoms after three periods was seen in Group 3 (R/P/R) (-0.5, 95% CI -2.9 to 1.9). CONCLUSIONS: Treatment with the complex remedy for 12 or 24 weeks did not result in clinically significant improvement of menopausal symptoms.

Adverse effects of homeopathy: a systematic review of published case reports and case series.

AIM: The aim of this systematic review was to critically evaluate the evidence regarding the adverse effects (AEs) of homeopathy. METHOD: Five electronic databases were searched to identify all relevant case reports and case series. RESULTS: In total, 38 primary reports met our inclusion criteria. Of those, 30 pertained to direct AEs of homeopathic remedies; and eight were related to AEs caused by the substitution of conventional medicine with homeopathy. The total number of patients who experienced AEs of homeopathy amounted to 1159. Overall, AEs ranged from mild-to-severe and included four fatalities. The most common AEs were allergic reactions and intoxications. Rhus toxidendron was the most frequently implicated homeopathic remedy. CONCLUSION: Homeopathy has the potential to harm patients and consumers in both direct and indirect ways. Clinicians should be aware of its risks and advise their patients accordingly.

[The application of metabonomics in modern studies of Chinese materia medica].

Metabonomics, a newly developing subject secondary to genomics, transcriptomics, and proteomics, is an important constituent part of systems biology. It is believed to be the final direction of the systems biology. It can be directly applied to understand the physiological and biochemical states by its "metabolome profile" as a whole. Therefore, it can provide a huge amount of information different from those originating from other "omics". In the modernization of Chinese materia medica research, the application of metabonomics methods and technologies has a broad potential for future development. Especially it is of important theoretical significance and application value in holistic efficacies evaluation, active ingredients studies, and safety research of Chinese materia medica.

Toxic hepatitis-associated aplastic anaemia after dual homeopathic remedies and Gymnema sylvestre use.

Hepatitis-associated aplastic anaemia (HAAA) is a rare condition characterised by onset of acute hepatitis which is followed by development of severe pancytopenia due to bone marrow failure within 6 months. This syndrome can be precipitated by acute viral infections, but the aetiology remains unknown in the majority. Drug-induced HAAA is extremely rare and has been reported with nutritional and dietary supplements in current literature. We report the first cases of ayurvedic herbal and homeopathic remedies-associated HAAA in two patients which proved fatal in both. Evaluation of patients with acute hepatitis and severe pancytopenia must include a detailed evaluation for complementary and alternative medicine use.

An outbreak of cutaneous infection due to Mycobacterium abscessus associated to mesotherapy.

INTRODUCTION: In February 2009 an outbreak of subcutaneous abscesses due to Mycobacterium abscessus was detected in Spain which affected healthy women who had undergone mesotherapy procedures in an aesthetic clinic. METHODS: Epidemiological research, health inspection and microbiological studies were conducted. The patients were given antibiotic treatment (according to susceptibility testing) with clarithromycin, and in some cases, combined with amikacin. RESULTS: Seventeen out of 77 patients treated in the clinic were affected. The products used for the injections were homeopathic drugs in multi-dose vials. The environmental samples were negative. The sterile injection equipment and the clinical procedures were evaluated as correct. The storage conditions for the drugs were also correct, and all the samples tested negative for Mycobacteria. However Paenibacillus provencensis was isolated from samples of unused multi-dose vials and the withdrawal of the product from distribution was ordered. Deficiencies were detected in the sterile products process of at the homeopathic drug factory, so the production line was suspended. CONCLUSIONS: The results of environmental investigation suggest the most likely cause of the outbreak could have been the contamination of the products in the factory, although there was no laboratory confirmation. The widespread use of homeopathic products in invasive procedures requires extreme control during the manufacturing, handling and packaging process. It is important to consider mesotherapy and parenteral use of homeopathic medicines as potential sources of infection and therefore the same precautions in the procedures and quality assurance of products should be applied as with any other drug or medical activity.

New homeopathic medicines: use of modern drugs according to the principle of similitude.

BACKGROUND: The homeopathic method is based on the application of the principle of therapeutic similitude (similia similibus curentur), using medicines that cause effects similar to the symptoms of disease in order to stimulate the reaction of the organism against disturbances. Such vital, homeostatic or paradoxical reaction of the organism can be scientifically explained on the basis of the rebound effect of modern drugs. AIMS: This article presents the conclusion of a study aiming at a method to use modern drugs with homeopathic criteria. METHODS: Adverse effects as catalogued in United States Pharmacopoeia Dispensing Information Drug monographs were collected. RESULTS: A homeopathic materia medica and repertory comprising 1251 modern drugs to be employed according to the principle of therapeutic similitude was developed. CONCLUSION: Besides supplying a basis for homeopathy as a medical rationale related to scientific pharmacology, this study makes available a method that may broaden the scope of intervention of homeopathy in present day diseases.

Methods of conservative and complex rehabilitation of patients with cicatricial eyelid malpositions are proposed. Conservative treatment included developed regimen of antihomotoxic agents, different techniques of graduated extension of scar tissues, special eyelid exercises. In complex management conservative treatment was provided along with surgery, in some cases botulinum toxin A was administered. Duration, time and priorities were determined.

Material Risks of Homeopathic Medicinal Products: Regulatory Frameworks, Results of Preclinical Toxicology, and Clinical Meta-Analyses and Their Implications.

Homeopathy is widely used and broadly accepted by health care professionals and the general public but less in academic circles. To assess possible material health risks of homeopathic medicinal products, it is necessary to identify, select, and synthesize the findings of recent reviews of controlled homeopathic clinical trials. Matching these findings with experimental data from toxicological studies helps to clarify what is known and not known about the material risks of homeopathic medicines. Rules for toxicological risk assessment and management need to be applied independently of individual attitudes towards specific therapeutic options. European regulatory bodies have developed special protocols and decision trees to assure the safety of nonindividualized homeopathic remedies. This narrative review leads to suggestions that could ease and improve toxicological decision making. No homeopathy-specific type or pattern of side effects could be extracted from the meta-analysis data. No differences in the frequency of adverse reactions between homeopathic treatment and placebo treatment could be seen, no matter whether adverse events were reported in a quantitative or a qualitative manner. Some patterns of side effects show that adverse reactions do not necessarily correlate with treatment but with the condition of the patient. Overall, the controlled clinical data available for the material risk assessment of homeopathic remedies support the statement that, if a risk exists, it must be so small that it has not yet been established. To make our risk findings useful for personal decisions regarding homeopathy, we provide a thought experiment based on four different health situations and ask the question: is homeopathy as a monotherapy or as an add-on treatment an option or should it be rejected?
