||Lady's mantle has the nickname, "a woman's best friend", and this is reflected in the ethnoveterinary use for retained placenta. Extracts from Alchemilla vulgaris L. inhibited 50% of the activity of porcine pancreas elastase at concentrations of 0.16 mg/ml, against a synthetic substrate. This study claimed a possible role by the extract in the protection of conjunctive and elastic tissues adversely affected by proteolytic enzymes. Mid level validity for retained placenta.
||Allium cepa oil given at 5 mg/kg body weight/day for 2 weeks showed anthelmintic activity in rats experimentally infected with Trichinella spiralis with a decline in the adult worms and muscle larvae. It was less effective as a prophylactic treatment prior to Trichinella spiralis infection. Mid level validity for endoparasites.
||Experiments with the intestinal parasite Entamoeba histolytica have shown that pure allicin inhibits both the cytopathological effects associated with infection and the growth of the parasite by blocking its cysteine proteases. Other studies with allicin have shown that it has inhibitory effects on a wide range of bacteria, on some fungi and on a few protozoans. Mid level validity for all uses.
||Treatment with garlic extract has been shown to activate macrophages, and suppress lesion growth in L. major infected mice. A garlic extract, showed no significant effect in the reduction of L. chagasi parasite load. The maximal survival of the garlic treated animals, despite their high parasitic burden, might be explained by a mild non-specific protective effect of the garlic treatment. In a L. major model, garlic treatment was more effective than chemotherapy with the first line drug glucantime, showing an additive effect with the antibiotic. There may be a protective effect of garlic treatment if administered previous to infection, in an immunoprophylactic vaccination schedule against visceral leishmaniasis. Mid level validity for all uses.
||Originally from China, this plant was an ingredient in the original marshmallows eaten by Egyptians and Romans. Over 1000 species in the Malvaceae family contain healing mucilage.

Arctium lappa constituents inhibited the tested endodontic pathogens Enterococcus faecalis, Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus subtilis and Candida albicans. A previous study on three forms of the rough extract of this plant (20% tincture, extract concentrated by rotaevaporation and lyophilized extract), found that the lyophilized extract was the most effective against B. subtilis and C. albicans. Mid level validity for mastitis.
||Arnica montana is indigenous to Central Europe. The methanol extract of Arnica montana flowers had a better antibacterial activity than the decoction (with MICs two or three times lower). The inhibiting concentrations of the methanol extract against P. gingivalis (3 of 5 strains), Prevotella spp., E. corrodens, Peptostreptococcus spp. and Actinomyces spp. had acceptable values (MIC ≤ 2048 mg/L) for the use in mouthwashes for the correct hygiene of the oral cavity. C. gingivalis and V. parvula (MIC 4096 mg/L) were less sensitive and so was F. nucleatum (MIC 16384 mg/L). Mid level validity for wounds.
|Artemisia sp., Artemisia
||Tarragon leaves are rich in iodine, minerals and vitamins C and A. This study compared the in vitro and in vivo anthelmintic activity of Artemisia brevifolia with levamisole. In vitro studies revealed anthelmintic effects of crude aqueous (CAE) and methanol extracts (CME) of Artemisia brevifolia (whole plant) on live Haemonchus contortus as evident from their paralysis and/or mortality at 6 h post exposure. For in vivo studies, the whole plant of Artemisia brevifolia was administered as crude powder (CP), CAE and CME at graded doses (1, 2 and 3 g kg(-1) body weight (b.w.) to sheep naturally infected with mixed species of gastrointestinal nematodes. Maximum reduction (67.2%) in eggs per gram (EPG) of faeces was recorded on day 14 post treatment in sheep treated with Artemisia brevifolia CAE at 3 g kg(-1) b.w. Levamisole produced a 99.2% reduction in EPG. However, increase in EPG reduction was noted with an increase in the dose of Artemisia brevifolia administered as CP, CAE and CME. Mid level validity for endoparasites.
||Groups of 11–12 angora goats were treated with an azadirachtin-rich extract of neem seeds with an azadirachtin concentration of 650 ppm or 125 ppm, with Neguvon((R)), or untreated (control). Their louse burden (Damalinia limbata Phthiraptera) was assessed for 22 weeks. A reduction in louse densities of 76–96% was observed from week 2 to week 18 after treatment with the neem solution containing azadirachtin at a concentration of 650 ppm. At the lower test concentration (125 ppm) a reduction of 60–92% was recorded from week 2 to week 14. The extract reduced the survival of both adult and nymph stages of Damalinia limbata.

There is a strong correlation between antioxidant activity and antiinflammatory activities of curcuminoids. Curcumin was also found to possess antiviral potential. Curcuma longa has an anti-thrombotic effect in mice. Mid level validity for proud flesh and caprine arthritis and as a palliative.
||Mosquito coils made from the leaves of Cymbopogon nardus had moderate knockingdown but insignificant killing effects on Aedes aegypti. High concentrations of C. nardus, were effective when screened against the mosquito Aedes aegypti under laboratory conditions using human subjects. Cymbopogon nardus provided at least 2 h complete repellency. The protection times of this oil was less when diluted. At 50% concentration, C. nardus showed 50 min protection and the repellent activity decreased to 30 min or less when diluted to 10%. The undiluted oil of C. nardus provided better protection against Ae. aegypti, Cx quinquefasciatus and An. dirus. Mid level validity as a fly repellent.
||Broom (Cytisus scoparius, syn. Sarothamnus scoparius) is a leguminous species with low contents of extractable condensed tannins, which would be unlikely to affect the digestion of nutrients in ruminants and has a high protein content. The young shoot tips of the broom, Cytisus scoparius, contain greater concentrations of sparteine than older leaves. Sparteine and the analogue BRB-I-28 produced a dose-dependent reduction in heart rate and blood pressure over the dose range 1–64 mumol/kg/min in pentobarbitone-anaesthetized rats subjected to left-ventricle electrical stimulation and occlusion of the left anterior descending coronary artery. High level validity as a cardiac tonic and browse plant.
||The LC50 values for Daucus carota against 4th instars of Culex annulirostris using acetone, ethanol, hexane, and methanol extracts were 236.00, 36.59, 77.19, and 241.8 mg/liter, respectively. Mid level validity for endoparasites.
||Echinacea purpurea has been investigated for its potential to enhance immune function, primarily through activation of innate immune responses. A time course study, using the time of SRBC immunization to mimic the onset of illness, examined the effects of 8 and 4 days of Echinacea purpurea treatment at 0.6 mL/kg/day. Only in the 4-day administration, with dosing beginning 1 hour after SRBC immunization, was there an observed enhancement of the antibody forming cell response. This supports the acute use of Echinacea purpurea as suggested by anecdotal reports, and demonstrates the potential for enhancement of humoral immune responses as well as innate immune responses. High level validity for immune protection.
||Fireweed (Epilobium angustifolium) has an abundance of vitamin C and was used by Indians and settlers who picked and boiled the fresh green sprouts in springtime. A tea was also made from the leaves. Fireweed (Epilobium angustifolium L.) extracts showed inhibitory activity against metallopeptidases. Fireweed contains several flavonoids and phenolic acids and an ellagitannin with anti-inflammatory activity. The dimeric macrocyclic ellagitannin oenothein B and other polyphenols may partly support the use of Epilobium extracts in folk medicine for prostate conditions. Epilobium angustifolium, Epilobium hirsutum, Epilobium palustre, Epilobium tetragonum and Epilobium rosmarinifolium ethanolic extracts showed antimicrobial activity in a range of concentrations between 10 and 650 microgml of dry extract. Epilobium angustifolium and Epilobium rosmarinifolium had broad spectrum activity against bacteria, yeasts and fungi. The analgesic properties of Epilobium angustifolium (Ea) was established using the dry extract of Ea obtained by evaporating a commercially available mother tincture. High level validity as a tonic feed.
||The short-term actions of Equisetum arvense and Lavandula officinalis dry extracts, and of isoquercitrin, a flavonoid found in Equisetum arvense, on in vitro fermentation by rumen microbes was investigated. The addition of Lavandula officinalis and Equisetum arvense enhanced the fermentation rate of the hay only substrate by 50%, through an increased release of acetate and propionate. Isoquercitrin lowered the fermentation rate of the other two diets. High level validity as a source of minerals.

Specific compounds in Rubus pinfaensis (triterpenoids, phenols) and Rubus imperialis (triterpenes) have antibacterial and antinociceptive properties, respectively. The leaves of Rubus idaeus have volatile compounds and waxes. Diterpene glycosides are found in the leaves of Rubus chingii and Rubus suavissimus and triterpenes in the leaves of Rubus imperialis and Rubus pinfaensis. Compounds in the leaves of Rubus idaeus, produce a relaxant response on a transmurally stimulated guinea-pig ileum in vitro, and are polar in nature. Mid level validity for milk production and to treat unknown illnesses.
||Rue has historically been a strewing herb and anti-plague plant. Common rue (Ruta graveolens) has an antifeedant activity against mahogany shootborer larvae (Hypsipyla grandella). Mid level validity as a fly repellent.
||The principal active component of Salix sp. is salicin, however the species also contains phenolic glycosides (salicortin, fragilin, tremulacin) in the bark. A standardized willow bark extract was examined in 127 outpatients with osteoarthritis and rheumatoid arthritis in 2 randomized, controlled, double-blind trials with follow up for 6 weeks. The difference between willow bark extract and placebo was not statistically significant in either trial. Ethanolic Salix extract 1520L inhibits COX-2-mediated PGE2 release through compounds other than salicin or salicylate. The Salix extract is a weak inhibitor of pro-inflammatory cytokines. Mid level validity for mastitis and unknown illnesses.
||210 patients with an exacerbation of chronic low back pain who reported current pain of 5 or more (out of 10) on a visual analog scale were randomly assigned to receive an oral willow bark extract with either 120 mg (low dose) or 240 mg (high dose) of salicin, or placebo, with tramadol as the sole rescue medication, in a 4-week blinded trial. The principal outcome measure was the proportion of patients who were pain-free without tramadol for at least 5 days during the final week of the study. The numbers of pain-free patients in the last week of treatment were 27 (39%) of 65 in the group receiving high-dose extract, 15 (21%) of 67 in the group receiving low-dose extract, and 4 (6%) of 59 in the placebo group (P < 0.001). Significantly more patients in the placebo group required tramadol (P < 0.001) during each week of the study. One patient suffered a severe allergic reaction, perhaps to the extract. High level validity for pain. Mid level validity for caprine arthritis.
||In the 17th century the Dutch found that the Chinese would trade three chests of tea for one of sage leaves. The ingestion of 200, 400 and 800 mg/kg of aqueous or 400 mg/kg of ethanolic extracts of Salvia fruticosa from day one to day six of pregnancy by female rats did not cause pregnancy failure. However, the ingestion of an ethanolic extract reduced the number of viable fetuses and increased the number of resorptions in the pregnant rats. A highly significant fetal resorptive effect was seen with the ethanolic extract, with 37% fetuses degenerated, while the aqueous extract showed significant activity with 31% of fetuses resorbed. The ingestion of Salvia fruticosa by adult male rats had no effect on the fertility of females impregnated by the treated males. However, the number of implantation sites and the number of viable fetuses were reduced. These losses appear to be due to either faulty preimplantation development or decrease in sperm function. Mid level validity for drying off.
||Ten Nubian goats were given oral doses of the fresh fruits and leaves of Cassia senna at 1, 5, and 10 g/kg/day. Eight goats died within 30 days and two others were slaughtered in a poor condition on days 18 and 29. The clinical signs shown were diarrhoea, inappetence, loss of condition, and dyspnea. Senna is not carcinogenic to rats given dosages of up to 300 mg/kg/day daily for 2 years. Mid level validity for diarrhea.
|Symphoricarposalbus var. laevigatus
||Symphoricarpos albus was found to have phenolic acids in the extracts and fractions from leaves, flowers and fruit with antimicrobial activity. Mid level validity for endoparasites.
||The ethnoveterinary uses of comfrey are related to medicinal uses recorded in Gerard and Culpepper. The antiinflammatory activity of comfrey (Symphytum officinale) is linked to rosmarinic acid, which has antioxidant, antiviral, bactericidal and viricidal activities. The soothing and wound healing properties are due to allantoin with reported anti-inflammatory, immunostimulant and vulnerary activities. Mid level validity as a laxative, for ketosis and to increase butterfat. High level validity for proud flesh, wounds and udder edema.
||Undiluted clove oil gave the longest duration of 100% repellency (2–4 h) against all tested species of mosquito: Aedes aegypti, Culex quinquefasciatus and Anopheles dirus. Low level validity for coccidia.
||Dandelion was first described as a medicine by Arabian physicians of the tenth and eleventh centuries. A comprehensive review of all studies conducted on dandelion has been recently published. One study found a partial inhibition of rat paw oedema induced by carrageenan and following intraperitoneal treatment with 100 mg/kg dm. A dried 80% ethanolic extract of Taraxacum officinale root administered orally at 100 mg/kg body weight 1 h before oedema elicitation inhibited carrageena ninduced rat paw oedema by 25%, versus a 45% inhibition with indomethacin at 5 mg/kg. The methanolic extract of flowers of Taraxacum officinale and Taraxacum platycarpum showed inhibition rates of 95 and 87%, respectively, of tetradecanoylphorbol-13-acetate (TPA)-induced ear oedema in mice. The triterpene uvaol isolated from dried flowers of Taraxacum platycarpum inhibited the TPA-induced inflammation at an equivalent level to indomethacin with 0.1 mg/ear being the 50% inhibitory dose. Extracts of Taraxacum officinale leaf and roots exhibited slightly lower inhibition rates of 69 and 51%, respectively, in the same assay. Dandelion leaf extract was also shown to have an anti-inflammatory activity on the central nervous system. Mid level validity for udder edema and high level validity as a feed.
||Ethyl acetate, chloroform and n-butanol extracts of Teucrium montanum showed a wide range of inhibiting activity against both Gram (+) and Gram (-) bacteria. Mid level validity for mastitis.
||Ethanolic and acetone extracts of Thuja orientelis were studied against III instar larvae of Anopheles stephensi and Culex quinquefasciatus. The ethanolic extract of T. orientelis was effective against both larval species with LC50 values of 13.10 and 9.02 ppm after 24 and 48 hours for anopheline and 22.74 and 16.72 ppm against culicine larvae. The acetone extract showed LC50 values of 200.87 and 127.53 ppm against anopheline and 69.03 and 51.14 ppm against culicine larvae. Mid level validity for endoparasites and lice. Low level validity for copper deficiency.
||Ulmus macrocarpa Hance has low to moderate anti-protozoal efficacy against Toxoplasma gondii and Neospora caninum. One-day-old broiler chicks were infected with Eimeria tenella and given various herbal extracts. Survival rates, lesion scores, body weight gains, bloody diarrhea, and oocysts excretions were investigated at the first and the second week after infection. All the birds treated with Ulmus macrocarpa survived. Lesion scores in the groups treated with Ulmus macrocarpa (1.40 +/- 1.14) were lower than the control. Mid level validity for endoparasites.
||Urtica dioica is reported to have anti-inflammatory, acute diuretic, natriuretic and hypotensive effects. The phenolic compounds present in Urtica dioica L. may contribute to its antioxidant activity. A water extract of Urtica dioica showed antimicrobial activity against 9 Gram-positive and Gram-negative bacteria and one yeast. A water extract of Urtica dioica also showed antiulcer activity against ethanol-induced ulcerogenesis and an analgesic effect. Ultica dioica agglutinin, a plant lectin, consists of seven individual isolectins. Isolectin I binds Zn(2+) ions. Mid level validity for zinc deficiency. Mid level validity for immune system protection. High level validity as a tonic and for diarrhea. Low level validity for endoparasites.
||A multicenter, prospective clinical trial was performed on 257 patients to study the efficacy and tolerance of a compound drug PRO 160/120 (Sabal palmetto and nettle) in elderly men with lower urinary tract symptoms due to benign prostatic hyperplasia. Group 1 of 129 patients received PRO 160/120 which was found to be superior to the placebo. High level validity as a tonic and for diarrhea.
|Usnea longissima, Usnea barbata
||Usnea barbata (L.) Mott and Usnea hirta (L.) Wigg hydroalcoholic extracts have antiinflammatory activity comparable to phenylbutazone and hydrocortisone hemisuccinate; the analgesic activity was close to that of noraminophenazone; the antipyretic activity was equivalent or better than aminophenazone. Usnea hirta has usnic, thamnolic and usnaric acids with antibiotic effects. Usnea longissima contains usnic and evernic acids which act as expectorants. Usnic acid has 2 enantiomeric forms with different activities including antimicrobial activity against Gram-positive and anaerobic bacteria including antibiotic-resistant pathogenic strains. It also has antiviral, antiprotozoal, antiproliferative, anti-inflammatory (equivalent to ibuprofen) and analgesic activity. High level validity for wounds and foot rot.
||The compounds absorbed into the rat blood after oral administration of ethanol extract of the stems and leaves of Vaccinium vitis-idaea were analyzed. Two compounds found in the plasma were arbutin and fraxin. Both arbutin and fraxin have anti-inflammatory, anti-coughing and phlegm-removing effects. Fraxin at the higher dosage tested had similar activity to dexamethasone; arbutin was less active. Docosane, quercetin, daucosterol, hyperoside, have also been isolated from the stem and leaf of the plant. Two huckleberry species, Vaccinium membranaceum and Vaccinium ovatum were evaluated for their total, and individual, anthocyanin and polyphenolic compositions. Vaccinium ovatum had greater total anthocyanin, total phenolics, oxygen radical absorbing capacity, and ferric reducing antioxidant potential than Vaccinium membranaceum. The pH and degrees Brix were also higher in Vaccinium ovatum. Each species contained 15 anthocyanins (galactoside, glucoside, and arabinoside of delphinidin, cyanidin, petunidin, peonidin, and malvidin) but in different quantities. They also had a different polyphenolic profile. The polyphenolics of both species had a high proportion of cinnamic acid derivatives and flavonol glycosides. The major polyphenolic compound in V. membranaceum was neochlorogenic acid, and in Vaccinium ovatum, chlorogenic acid. Mid level validity for ketosis and as a feed supplement.
||Valerian was used in World Wars 1 and II to treat shell shock. A review of Valeriana officinalis states that the compounds in the volatile oil vary due to genetics and environmental causes. Main constituents include the monoterpene bornyl acetate and the sesquiterpene valerenic acid. Some sesquiterpenes act on the amygdaloid body of the brain and valerenic acid inhibits enzyme-induced breakdown of GABA in the brain producing sedation. The valepotriates are changed into homobaldrinal which reduces the spontaneous motility of mice. The aqueous extracts of the roots contain GABA which could cause sedation depending on its bioavailability. A lignan, hydroxypinoresinol, can bind to benzodiazepine receptors.
||The use of mullein for respiratory problems is derived from traditional folk medicine. Extracts of Verbascum thapsus exhibited antiviral activity against herpesvirus type 1 and influenza viruses. High level validity as a respiratory tonic.
||The components of the pure plant-based extract AS 195 (Folia vitis viniferae) are flavon(ol)-glycosides and glucuronides with quercetin-3-O-beta-D-glucuronide (main flavonoid) and isoquercitrin (quercetin-3-O-beta-glycoside; a secondary flavonoid). Low level validity for unknown illnesses.
||The use of the stigma and styles of Zea mays as a diuretic is found only in those parts of Italy where the Spanish influence was strong. This ethnomedicinal use is also found in the Caribbean and in Latin America and is still found in Spain. Corn silk aqueous extract is diuretic in rats at large dosages. Mid level validity for udder edema.
||Zingiber officinale is active against Helicobacter pylori strains, and also has antiinflammatory, antioxidant and antitumoral activity. An extract from the root of Zingiber officinale reduced the minimum inhibitory concentrations of aminoglycosides in vancomycin-resistant enterococci. The effective compound -gingerol with its detergent-like effect potentiated the antimicrobial activity of the aminoglycosides. High level validity for diarrhea and scours.
