(3) Study evaluated the analgesic properties of S. torvum leaf syrup in Swiss albino mice using the formalin test and hot plate method. Results showed dose dependent analgesic effect in the formalin test, At 1000 mg/kg, the syrup showed analgesic effect by hot plate test closely comparable to Paracetamol control. (63)
Metabolic and Blood Pressure Effects: Methanolic extract of Solanum torvum reduced blood pressure, vascular reactivity changes to catecholamines and reversed metabolic alterations induced by fructose. (4)
Antioxidant Effects / Cytochrome Enzyme Inhibiting / Free Radical Scavenging: Study showed S torvum is a natural source of polyphenolic antioxidants, which have cytochrome P450 2E1 enzyme inhibiting and free radical scavenging properties, and suggests a potential use for reducing oxidative stress in diabetes. (5)
Antibacterial: In an in vitro study of S. torvum against human pathogenic strains, the water and ethanol extract was found effective against all bacterial strains with an inhibition comparable to that of commercial antibiotics. (8)
Antibacterial / Antifungal / Roots: Methanolic extracts of roots of S. torvum exhibited promising antibacterial and antifungal effects on all organisms tested (6 gram(+), 9 gram(-) and 8 pathogenic fungi). (9) Study evaluated various extracts of roots of S. torvum against six Gram negative and three Gram positive bacteria by disc diffusion. E. coli was the only Gram negative bacteria that showed sensitivity to the root extract. An ethanolic extract showed strong activity against S. aureus and Bacillus sp. with zone of inhibition of 20.5 mm and 14 mm, respectively. (52)
Anti-H. Pylori / Antifungal: Helicobacter pylori infection is associated with an increased risk for duodenal ulcers, gastric ulcers, gastric adenocarcinoma and gastric lymphomas. Study of S. torvum extracts showed inhibition
of H. pylori growth. S. torvum chloroform extract also suppressed H. pylori-induced apoptosis. Further studies are needed to elucidate the molecular mechanisms of H pylori growth inhibition. (10)
Antimicrobial: Study showed S. torvum not only demonstrated antimicrobial activity but the extract also exhibited significant control of seed borne pathogenic fungi and bacteria. Results suggest a potential for exploitation for paddy disease management. (13) Ethanolic extracts of stem, leaf, pericarp, and root showed antibacterial activity against Bacillus sp, K. pneumoniae, S. aureus, and Micrococcus sp and antifungal activity against Tricophyton surans and Aspergillus niger. (see constituents above)  (39)
Alkaloids: Comparative study of S.. torvum Sw grown in India and Chiapas, Mexico, showed similar total alkaloidal content. However, solasodine was found only in Chiapas plants. Study also yielded solasonine and solamagine, two glycosylated compounds of solasodine, which can b used as substrate for the production of important steroids in pharmacology. (14)
Acute and Subacute Toxicity Studies: Study of hydro-ethanolic extract of the ripe fruit showed it was not highly toxic. However, consumption at higher doses over 16 g/kg could cause liver injury. Moderate consumption of small doses up to 1 g/kg twice a week for 6 weeks appeared safe. (15)

Results showed antidepressant, anxiolytic and adaptogenic activities suggesting involvement of noradrenergic, dopaminergic, serotonergic and gabaergic mechanisms. (18)
Oral Toxicity Studies / Leaves and Stems: Study evaluated the oral toxicity in Sprague Dawley rats using a decoction of leaves and stems. The plant decoction was administered at a single dose of 2000 mg/kg of body weight. Results showed no clinical signs of toxicity or animal deaths. The tested decoction, administered at one dose, is regarded as unclassified for the animal model and dosage used. (19)
Bruhati moola / Anti-Inflammatory: Study showed Bruhati moola is not only effective in inflammation, but also safe to use without any harmful effects. (20)
Cardioprotective / Doxorubicin-Induced Cardiotoxicity / Flavonoids: Oxidative stress is the main factor in doxorubicin-induced cardiotoxicity. Study showed S. torvum has the potential of preventing cardiotoxicity induced by Doxorubicin. The protection was attributed to flavonoids. (21)
Cardiac Effects / Hypotensive / Decreased Anti-Platelet Aggregation: Study evaluated the cardiovascular activity of aqueous and methanol extracts of fruits of S. torvum. The methanol extract reduced heart rate at all test doses. Both extracts induced significant reduction in arterial blood pressure probably from the bradycardic effect. The aqueous extract dose-dependently inhibited platelet aggregation. (22)
Modulation of Lysosomal Activities / CCl4 Vapour Induced Liver Damage: Study showed Carica papaya and Solanum torvum reversed the effect of carbon tetrachloride vapour induced liver damage. The plant extracts prevented leakage of lysosomal enzymes by increasing the stability or decreasing vulnerability of lysosomal membrane possibly through its antioxidant property. (23)
Methyl Caffeate / α-Glucosidae Inhibition / Anti-Diabetic: Study isolated methyl caffeate, a rat intestinal sucrase and maltase inhibitor. Its moderate inhibitory action against α-glucosidase presents a potential prospect for the antidiabetic use of S. torvum fruit. (24)

(26)
Hypertensive Effect / Toxicity Study: Study evaluated the acute toxicity and effect of oral aqueous extract of S. torvum in chronic arterial hypertension induced by L-NAME. Results showed no mortality nor visible signs of toxicity. AEST induced potentiation of arterial hypertension and cardiac hypertrophy in
L-NAME treated rats, an effect that may be due to reduction in sensitivity to vasorelaxant agents and increase in hypersensitivity to contractile factors. Its in vitro vasocontractile activity may be from activation of both α1-adrenergeic pathway and calcium influx. (27)
Hepatoprotective / CCl4 Induced Toxicity: Study of a hydroalcoholic extract of fruits showed promising hepatoprotective activity as evidenced by biochemical parameters. However, the overall hepatoprotection is low compared to standard drug silymarin. (29) Study showed Solanum torvum reversed carbon tetrachloride damage associated with activities of lysosomal enzymes vis NAG, glucoronidase, alkaline phosphatase and bilirubin levels. (30)
Antifungal / Antimycotoxigenic / Leaves: Study investigated the antifungal effect of ST leaves against field and storage fungi. Study isolated an antifungal compound, torvoside K, which inhibited the growth of all fungi tested, with complete inhibition in vitro and in vivo of growth of A. flavus and F. verticillioides and aflatoxin B1 and fumonisin B1. (31)
Anti-Inflammatory / Toxicity Study: Study evaluated a methanolic extract of raw berries showed anti-inflammatory activity by carrageenan induced paw edema in an animal model.

Benign Prostatic Hypertrophy: Study showed the therapeutic potential of S. torvum for the treatment of BPH because of it anti-inflammatory, immunomodulating and antioxidant activity. (36)
Antimitotic / Anticancer: Study of extracts of S. torvum showed to be extremely effective in prevention of cell proliferation of mammary gland breast adenocarcinoma cell lines The pronounced antimitotic and anticancer activities was attributed to its potential antioxidant property and the key roles of polyphenols, steroidal saponin glycoside, alkaloids and flavonoids. (38)
Anthelmintic: Study of S. torvum fruits showed anthelmintic activity against Ascaridia galli, a common gastrointestinal parasite of domestic fowl (Gallus gallus domesticus). The report throws light on the use of S. torvum fruits has herbal anthelminticide for humans. (40)
Methyl Caffeate / Antidiabetic / Antihyperglycemic: Study of methyl caffeate in streptozotocin induced diabetic rats showed significant reduction in blood glucose and increased body weight. Methyl caffeate treated diabetic rats showed upregulation of GLUT4 and regeneration of ß-cells in the pancreas. Results suggested a potential for a potent oral antidiabetic drug. (42)
Toxic Myopathy in a Case of Acute Toxicity:Toxicity of berries appear to be related to the concentration of steroid glycoalkaloids in berries, which are higher in toxic berries than in non-toxic berries.. Toxicity of berries may be related to the maturity of berries or environmental stresses. In a toxicity case, electromyography showed myotonia and early recruitment of motor units with full interference pattern. The responsible chemical, although unknown, is likely due to solanaceous steroidal glycoalkaloids. (43)

• Cytotoxicity Evaluation / HFF Cells (Human Foreskin Fibroblasts) / Fruit: Study evaluated the cytotoxic activity of 70% ethanolic extract of fruits of S. torvum on HFF cells in in vitro culture. Phytochemical screening yielded alkaloids, tannins, polyphenols, saponins, and flavonoids. Results showed the extract has cytotoxic activity on tested HFF cells. At 800 µg/ml, survival rate of HFF cells increased from 100% to 4% of living cells. Study suggests the extract is cytotoxic on HFF cells and advises further studies on toxicity and cautions on the use of S. torvum fruits in traditional medicine. (59)
• Acute Toxicity / Electrophysiological Findings / Fruit: Study describes the electrophysiological findings in a patient with acute Solanum torvum (susumber berry) poisoning. The patient presented with vision changes, dizziness, difficulty speaking, and muscle weakness. Neuro exam showed intact mental status, opsoclonus, severe dysarthria, mild distal upper and lower extremity weakness with tenderness on palpation, delayed motor reflexes and ataxia. MRI of the brain and CSF studies were unremarkable. Lab showed a peak creatine kinase of 1886 IU/L. EMG showed myotonia and early recruitment of motor units with interference pattern. Poisoning with berries appears to cause a toxic myopathy. The chemical cause may be from a class of solanaceous steroidal glycoalkaloids. (see Toxicology below) (61)
• Diuretic / Seed and Fruit Wall: Study evaluated methanol extracts of seeds and fruit wall of S. torvum for diuretic activity in doses of 150, 300, and 450 mg/kbw in albino rats. Results revealed the fruit wall methanol extract showed significant diuretic activity compared to the seed ME. (62)
• Immunomodulatory / Erythropoietic / Fruits: Study evaluated the effect of S. torvum fruit extracts on delayed type hypersensitivity (DTH) response, hemagglutinating antibody (HA) titer, WBC, RBC, and Hb concentration in Sprague Dawley rats. Results showed concentration-dependent immunostimulant and erythropoietic activity as evidenced by significantly enhanced DTH response, increase HA titer and WBC count, reversal of PHZ-induced anemia, increases in RBCs and Hb concentrations. (64)
• Effect on Blood Pressure and Metabolic Alterations in Fructose Hypertensive Rats: Study evaluated the effect of ethanol extract of S. torvum on systolic blood pressure (SBP), vascular reactivity, serum glucose, triglycerides, cholesterol, insulin, and uric acid in fructose induced hypertension. Results showed the S. torvum could prevent the development of high blood pressure induced by fructose-rich diet probably via reversal of metabolic alterations induced by fructose. (65)

Caution !
• Toxicology: Reports on two outbreaks (New York and Toronto) of poisoning by cucumber berries (Solanum torvum) and detection of alkaloids. Consumption of berries caused varying degrees of GI distress, diarrhea, weakness, dizziness, slurring of speech, ataxia, cranial nerve deficits and respiratory difficulties. Poisonous berries are indistinguishable from non-toxic varieties. Solasonine and larger amounts of solamargine and other steroidal glycoalkaloids were isolated from the toxic berry strains.
• Published cases are rare. Toxicity may be related to the maturity of berries, environmental stresses, or the concentration of steroid glycoalkaloids in the berries. Steroid glycoalkaloids inhibit serum and erythrocyte acetylcholinesterase and butrylcholinesterase, which may cause the spectrum of clinical manifestations. (61)
