Treatment of Organic Livestock with Medicinal Plants: A Systematic Review of European Ethnoveterinary Research

Background: The EC Regulation for Organic Farming states that organic livestock should be treated preferably with phytotherapeutic products. In spite of the high importance of organic livestock in Europe, primarily ruminants, today almost no phytotherapeutic product is registered for livestock. Also, information regarding veterinary phytotherapy is rare. The aim of this paper is to find approaches to cope with health problems of organic ruminants in Europe on the basis of findings from the European ethnoveterinary medicine (EuEVM). Methods: A systematic review of ethno-biomedicinal papers was conducted with the aid of the Scopus database, and 75 papers, from European countries were analyzed regarding ethnoveterinary information. Results: A total of 590 plant species referring to 102 different plant families are reported to be used for animal treatment, with Asteraceae, Fabaceae and Lamiaceae being the most important families. The traditional use of some plant species (e.g. mallow, chamomile, wormwood) corresponds with findings from recent scientific literature. The large number of less studied plant species, such as white lupin as an antiparasitic herb, and Helleborus spp. as potential immunostimulatory agent, opens an interesting field for future research. Conclusions: In general, EuEVM provides interesting treatment approaches for gastrointestinal and dermatological disorders as well as parasitosis. Findings regarding disorders of female genital or respiratory tract are less consistent. Nevertheless, EuEVM offers a solid basis for stimulating research in veterinary phytotherapy in Europe with a perspective to solve animal health problems in organic or even nonorganic ruminant production.

“…Furthermore, callus grown under periodic light enhanced the accumulation of TCT (1.7 ± 0.2 mg.CE.g −1 in cotyledon-derived callus and 0.84 ± 0.07 in leafderived callus) as compared to dark incubation. Similarly, (Castro et al 2016) found a positive response of light on the TCT in Byrsonima verbascifolia callus cultures, whereas Favre et al (1991) found no effect in Quercus callus. The levels detected in the present study were found to be higher than those reported in different aerial parts of Moroccan carob, which ranged from 0.45 to 2.64 and from 15.8 to 18.08 mg.GAE.g −1 of phenolic content in intact carob leaves and pulp (Hajaji et al 2010) and from 0.25 to 1.02 mg.CE.g −1 of condensed tannins in carob pulp (El Bouzdoudi et al 2016).…”

Carob (Ceratonia siliqua L.) is an important Mediterranean plant species with worldwide commercial and medicinal uses. The establishment of a callus culture protocol as an alternative system to produce polyphenols of chemical and pharmaceutical interest was made in the present study for the first time in carob. Explant type and the light regime are two important factors that influence morphogenic responses and biochemical production. Maximal callus induction (100 %) and biomass accumulation were obtained in cotyledon explants under both tested light regimes (16-hour photoperiod and darkness). However, leaf callus produced a higher amount of polyphenols (TPC) and flavonoids (TFC) but a lower amount of total condensed tannins (TCT) as compared to cotyledon callus. Light treatment has significantly increased TCT content but decreased the antioxidant activity in carob callus cultures. Strong and positive correlations were obtained between TPC and TFC and the antioxidant activities with correlation coefficients ranging between 0.68 and 0.98. The obtained results indicate that calli of C. siliqua have the potential for enhanced production of phenolic compounds with antioxidant activity that is favored by culture under dark condition.
