Evaluation of the Efficacy of Crataegus oxyacantha in Dogs with Early-Stage Heart Failure.

BACKGROUND: Myxomatous mitral valve disease (MMVD) is the most common cardiopathy in middle-aged dogs. When the dog is asymptomatic and has an enlarged left atrium, treatment is beneficial; however, some allopathic drugs are very costly and may produce side effects. To extend the duration of this asymptomatic phase, complementary therapies such as herbal medicine and homeopathy are available. Although herbal therapy with extract of Crataegus oxyacantha is beneficial, there is a risk of adverse reactions-unlike with homeopathy, where the risk is minimized with the administration of ultra-diluted doses. OBJECTIVE: This study evaluated the efficacy of Crataegus oxyacantha, as mother tincture (MT) and in 6 cH homeopathic formulation, in treating the initial phase of heart failure due to MMVD in a veterinary clinic setting. METHODS: A total of 30 dogs with MMVD, 7 years or older and weighing up to 10 kg, were randomized into three groups as follows: Crataegus 6 cH, Crataegus MT, and hydroalcoholic solution (placebo). Animals were evaluated through echocardiography parameters, laboratory blood tests, and systolic blood pressure (SBP) measurements at 30, 60, 90, and 120 days after initiation of therapy, for statistical analysis and monitoring of the blinded study. RESULTS: Patients who received Crataegus 6 cH showed a reduction in SBP 60 days after treatment, while those receiving Crataegus MT exhibited a reduction 90 days after the therapy was initiated. There was a significant linear regression when evaluating the effect of treatment with Crataegus 6 cH on SBP measurements over the evaluation intervals (linear equation: SBP = 176.57 mm Hg - 0.21x, where x represents days of treatment). There was an increase in both fractional shortening and isovolumetric relaxation time for those patients receiving the homeopathic formulation. CONCLUSIONS: Therapy with Crataegus was beneficial for hypertensive and cardiopathic dogs with MMVD, extending the duration of the asymptomatic phase. The reduction in SBP occurred more swiftly in the 6 cH group than in the MT-treated dogs.

Bibliometric trend analysis of non-conventional (alternative) therapies in veterinary research.

Background: There is an increased interest in Non-Conventional Therapies (NCTs), often referred to as complementary and alternative medicines, in veterinary clinical practice.Aim: To map the bibliometric outputs of NCTs in veterinary medicine, and identify which are most prevalent, and the extent to which their publishing has increased.Methods: Text mining algorithms were applied to detect 17 NCTs-related terms (acupuncture, ayurveda/ayurvedic, traditional Chinese medicine, traditional medicine, chiropractic, electroacupuncture, essential oil, plant extract, ethnopharmacology, herbal medicine, homeopathy, low-level laser therapy, medicinal plant, natural product, osteopathy, phytotherapy, and massage) in the title, abstract or keywords of all retrievable literature until 2020 under the PubMed MeSH term 'veterinary' (N = 377 556). Point prevalence, incidence by decade and cumulative incidence were calculated.Results: Bibliometric trend analysis revealed an overall increase in NCTs-related terms over the last 20 years, with a substantial growth of studies mentioning plant extracts, essential oils and medicinal plants. Traditional Chinese medicine, herbal medicine and natural product have also increased in the same period, although their numbers remain low. Conversely, reference to acupuncture has decreased in the last decade when compared with the previous decade, whereas references to homeopathy, electroacupuncture, osteopathy and chiropractic remained scarce, suggesting that their use in veterinary clinical practice may not be based on published evidence.Conclusion: Further reviews to explore this issue are warranted, differentiating secondary from primary literature, and assessing relevance and methodological quality of individual studies, following the principles of evidence-based veterinary medicine.

Milk and plasma disposition of thymol following intramammary administration of a phytoceutical mastitis treatment.

Despite the recent growth of the organic dairy industry, organic producers and veterinarians have limited information when choosing mastitis treatments for animals in organic dairy production. Organic producers commonly administer homeopathic or other plant-based products without having research evaluating the efficacy of these products and using estimated or no withholding times to treat mastitis and other health problems in their herds. In this pilot study, we attempted to identify several active ingredients of Phyto-Mast (Penn Dutch Cow Care, Narvon, PA), a plant-based mastitis treatment used on organic dairy farms, and to quantify the product residue in milk and plasma after intramammary administration. We developed an assay to quantify thymol (one of the active ingredients in Phyto-Mast) in milk and plasma using gas chromatography and mass spectrometry (GC-MS). Thymol is a volatile aromatic compound with antiinflammatory properties. As a model for dairy cows, 5 healthy, lactating alpine dairy goats were given 5 mL of Phyto-Mast per udder half. For 10 d following treatment, we analyzed blood and milk samples for thymol residues using GC-MS. The GC-MS assay was very sensitive for thymol detection, to a concentration of 0.01 µg/mL in plasma. Using thymol as a marker, Phyto-Mast was detectable and quantifiable in plasma beginning with the 15-min posttreatment sample, but was no longer detectable in the 4-h posttreatment sample. Thymol residues were only detected in the 12-h posttreatment milk sample. An inflammatory response was not evident in the udder following phytoceutical administration. Although this study provides information about the elimination of thymol, the product contains several other active chemicals, which may have different pharmacokinetic behaviors. Further analysis and additional study animals will help to determine a milk withholding time for Phyto-Mast. Given the recent growth of the organic dairy industry, understanding the pharmacokinetics of therapeutics used in organic production and developing accurate withholding recommendations will help to ensure milk safety.

Anthelmintic efficacy of neem (Azadirachta indica A. Juss) and the homeopathic product Fator Vermes in Morada Nova sheep.

Gastrointestinal nematodes are becoming increasingly resistant to the commercial products used to control them. The cost of routine vermifuge applications on herds and the problem of residues in animal products and the environment have prompted research on the anthelmintic activity of plant extracts. This work examines the anthelmintic action of neem and the homeopathic product Fator Vermes in sheep kept in a pasture for 18 months. Forty sheep of the Morada Nova breed were divided into four treatments and the control, according to the EPG. During the experiment, each animal received 100 g/day of shredded corn and did not receive protein supplementation. In treatment 1 (control), the animals received only shredded corn. Treatment 2 received 1.6 g/(animal day) of the homeopathic product mixed with the shredded corn, and treatments 3, 4 and 5 received, respectively, 12.5, 25.0 and 37.5 g/(animal day) of dried Azadirachta indica leaves mixed with the shredded corn. The neem was administered for alternating 15-day periods and the homeopathic product daily for 18 months. There were 39 fortnightly fecal collections made to count the EPG, and fecal cultures were performed monthly. The following genera, in percentage, were identified: Haemonchus: 65.58+/-3.27, Trichostrongylus: 15.92+/-7.38 and Oesophagostomum: 18.50+/-6.22. The treatments evaluated were not effective in controlling gastrointestinal nematodes (P>0.05), whose mean log(10) counts (EPG +1) and standard errors for treatments 1-5 were respectively 3.55+/-0.28; 3.48+/-0.31; 3.90+/-0.29; 2.78+/-0.29 and 3.48+/-0.30. A significant effect (P<0.0001) was observed of the periods of the year when the 39 collections occurred. Because of the diet deficient in raw protein, the sheep had higher average EPG counts, for all the treatments, at the end of the dry season, and the opposite occurred in the middle of the rainy season.

Clinical management of idiopathic epilepsy in dogs with homeopathic Belladonna 200C: a case series.

Epilepsy is an important neurological disorder in dogs. Belladonna 200C was evaluated in 10 dogs with idiopathic epilepsy. During the seizure phase, 3-4 drops of Belladonna 200C were administered orally at 15 min intervals until considerable reduction in seizure activity, then four times daily. Four dogs with head shaking syndrome in addition to seizures were given Cocculus 6C, 3-4 drops orally weekly for 3 months in addition. Numbers of fits reduced to 2-3 during first 2 weeks post-therapy and then became occasional in next 2 weeks. With continuation of Belladonna therapy, no fits were observed during 2-7 months follow-up. In two cases epileptic fits reappeared within 15-25 days of cessation of therapy. Belladonna therapy was resumed and seizure control was again achieved. Owners were advised to continue the therapy at least twice daily until there were no fits for 2-3 months. Liver specific enzymes were monitored, no abnormalities were observed.

Nontraditional approaches to pain management.

The word nontraditional in the context of this article implies those modalities not normally taught in veterinary medical schools. This word has the same definition of Complementary and Alternative Medicine (CAM) as put forth by the Harvard medical school. CAM is a field of medicine that has enjoyed a recent increase in popularity in both human and equine medicine, particularly in regard to pain management. Some of the more recognized modalities include acupuncture, herbalism, and homeopathy. A brief discussion regarding the theory, scientific evidence and use of these therapies in the treatment of pain will be discussed.

Animal welfare in relation to standards in organic farming.

The new EU-regulations on organic farming (1804/1999) are also influencing the animal welfare. A lot of positive regulations is to find, but also regulations that seen to mind more about the general public and customer and their view on organic farming, than the health and welfare of the animals. The paper specially focus on the impact of the regulations and the recommendations that phytotherapeutic essences and homeopathic products take precedence over the so called chemically-synthesised allopatic veterinary medical products, and that the use of the same is prohibited for preventive treatments. Key questions here are the lack of scientific evidence concerning homeopathy in animals, and that Swedish veterinarians are not allowed to work with homeopathy. Differences in interpretation of the regulations between animal owners and veterinarians will also be discussed. What is a disease that needs treatment? Who is to decide about the treatment? Parasitic infections are discussed as an illustrative example. Other consequences of the regulations concerning the animal welfare are problems in certain geographical zones, for instance subarctic areas where necessary crops are impossible to grow. Animal transports and splitting mother-offspring are briefly discussed as future problems to be handled in the regulations, and the paper ends by presenting the need of regulated herd health control programs in organic husbandry, which can detect and focus on welfare and production problems. The organic movement is not static, and must not be so.
