Gen  info
- Solanum lasiocarpum is of interest to botanists because of its close resemblance and close relation to South American species, the cocona (S. sessiliflorum), the naranjilla (S. quitoense), and the pseudolulo (S. pseudolulo). Grown outside of their native range, these four plants will readily hybridize, producing sterile offspring, and, thus, the potential the enhance the commercial availability of each of the species elsewhere in the world. (4)
- Taxon notes: The binomial "Solanum indicum" is confusing to both lay people and academics due to the many authorities that have attempted to pin it down taxonomically. Consequently when one finds a photo or a text referring to "Solanum indicum" one is never sure if it refers to "Solanum anguivi" or "Solanum violaceum" or even "Solanum ferox". It has been rejected by taxonomists as the following notes from USDA - ARS - GRIN attest but the literature is riddled with "Solanum indicum" so all the common names associated with it become even more unreliable than usual.
- "Solanum indicum L., nom. rej., a rejected name (nomen utique rejiciendum) under Vienna ICBN Art. 56 & App. V that is unavailable for use.
- Hepper, F. N. 1978. (456,457) Proposals to list Solanum indicum L. and Solanum sodomeum L. as rejected names under Article 69 of the ICBN. Taxon 27:555."

Studies
(Note)
Studies include published studies on Solanum lasiocarpus and studies from previous pages of S. indicum and S. ferox (Tarambulo). The species have been subject of taxon conflicts, and attribution of scientific studies are likkewise fraught with conflicts. Also, in the process of merging the pages, the links for earlier studies on Solanum indicum are no longer available. Studies below are for both Solanum lasiocaepum and its synonym S. indicum. Studies will be added or deleted as information becomes available.
Hepatoprotective / Antioxidant / Berries: Study evaluated the hepatoprotective and antioxidant activities of crude ethanolic extract of S. indicum berries in CCl4-induced acute hepatotoxicity in rats. Results showed significant inhibitory activity on peroxides formation in linoleic acid emulsion in a dose-dependent manner. The hepatoprotective effect was attributed to its marked antioxidant activity from flavonoids with its free radical scavenging properties. (6)
• Anticonvulsant / Fruits: Study evaluated the anticonvulsant activity of methanol extracts of Crinum jagus and Solanum indicum bulbs and fruits, respectively, using mice and electroconvulsive shock equipment. C. jagus showed greater anticonvulsant effect. S. indicum showed activity at 112.50 mg/kg body weight. (7)
• Antitumor / Cytotoxicity on Seven Cancer Cell Lines: Study of whole plant yielded beta-sitosterol (1), beta-sitosterol glucoside (2), dioscin (3), methyl protoprosapogenin A of dioscin (5), methyl protodioscin (6) and protodioscin (7). Both CHCl3 soluble and insoluble fractions of ethanolic extract showed cytotoxicity on seven cancer cell lines: Colo-205 (colon), KB (nasopharynx), HeLa (uterine cervix), HA22T (hepatoma), Hep-2 (laryngeal epidermoid), H1477 (melanoma) and GBM8401/TSGH (glioma). (8)
• Cytotoxic / Solavetivone / Constituents: Study yielded solavetivone which was found to be cytotoxic to OVCAR-3 cells with an IC50 of 0.1 mM. Other compounds isolated were a novel solafuranone and three known compounds: scopoletin, N-(p-trans-coumaroyl)tyramine and N-trans-feruloyltyramine. (9)
Antibacterial / Leaves: Ethanolic extract of leaves showed antibacterial activity against Staphylococcus aureus, Bacillus cereus, E coli. A chloroform, acetone, and ethanol extracts showed activity against pseudomonas. (7)
Anticariogenic / Flesh and Leaf: Dental plaque is a biofilm produced by cariogenic bacteria that attaches to the surface of teeth. Ethanolic extract from flesh and leaf of S. ferox has shown anticariogenic properties against S. pyogenes and S. aureus. The anticariogenic properties may be due to presence of phytochemicals such as alkaloids, flavonoids, and tannins. (15)
Indiosides / Anticancer: Studies have yielded several synthetic indiosides from S. indicum and shown to have anticancer effects. Results showed indiosides have a dose-dependent inhibitory effect on proliferation of Bel-7402 cells, and can induce apoptosis through mitochondria-dependent pathway. (16)
Antibacterial / Fresh Leaves: Study evaluated the antibacterial potential of Solanaceae plants i.e., solanum indicum, S. xanthocarpum, and Physalis minima against selected pathogenic microorganisms. Ethanol and methanol extracts of fresh leaves of Solanum indicum showed moderate antibacterial activity against Bacillus spp., Corynebaterium diphtheriae, Streptococcus spp., Pseudomonas spp., and Salmonella typhimurium. (17)
Cardiotonic / Laxative / Fruits: Study evaluated crude methanolic extract of fruits of Solanum indicum for laxative and cardiotonic activity in experimental animals. Results showed significant laxative activity (p value <0.01) and marked dose-dependent cardiotonic activity. (18)
Anthelmintic / Fruits: Previous study reported on the strong anthelmintic activity of fruits of Solanum indicum. Study partially purified at least four different anthelmintic compounds. (19)

Toxicity Report
Diabetes Insipidus:
Study reports on a case of diabetes insipidus after seven doses of concentrated solution of Solanum indicum over two weeks. The diagnosis was confirmed by a water deprivation test and a low serum ADH. Results suggest that excessive doses of S indicum may cause central diabetes insipidus. (10)

The compilation now numbers over 1,300 medicinal plants. While I believe there are hundreds more that can be added to the collection, they are becoming more difficult to find. If you have a plant to suggest for inclusion, native or introduced, please email the info: scientific name (most helpful), local plant name (if known), any known folkloric medicinal use, and, if possible, a photo. Your help will be greatly appreciated.
