Botany
Trompang elepante is an annual, erect, branched, hirsute plant, 15 to 50 centimeters high. Leaves are opposite or alternate, ovate to oblong-ovate, somewhat hairy, acute or acuminate, base decurrent along the petiole, 3 to 8 centimeters long. Flowers are small, and borne on one side of curved, terminal, or leaf-opposed spikes which are 3 to 8 centimeters long. Calyx is green.
Corolla is pale lavender to nearly white, funnel-shaped, and about 5 millimeters long, with a slender and cylindric tube and the limb 3 to 3.5 millimeters in diameter. Stamens are 5, inserted on the corolla tube. Ovary completely or imperfectly 4-celled, 4 ovules, style terminal or leaf opposed, 3 to 10 centimeters long, flowers all in one side, the lower ones opening first. Fruit id 4 to 5 millimeters long, composed of 2, ovoid, beaked nutlets.

Studies
Gastroprotective / Antimicrobial: Study of the aqueous extracts of dried leaves of Heliotropium indicum showed dose-dependent gastroprotective effects. (1)
Wound Healing: (1) Study of 10% topical application increased the percentage of wound contraction, increased tensile strength and decreased time of healing from rapid epithelization and collagenization.
Wound Healing / Comparative Study: Ethanolic extract of HI showed to have better wound healing activity than P zeylanicum and A indica. (5)
Wound Healing: Study showed significant promotion of wound healing with methanol and aqueous extracts. In the wound infection model (Staph aureus and P. aeruginosa), the methanol extract showed significant healing activity compared to standard nitrofurazone.
Anti-Tumor: Isolated oxide of alkaloid indicine from HI showed significant anti-tumor activity in carcinosarcoma, leukemia, and melanoma tumor systems.
Anti-Inflammatory: Study of H indicum produced significant antiinflammatory effect in both acute and subacute models of inflammation, with activities comparable to acetylsalicylic acid and phenylbutazone respectively.
Anti-Inflammatory: Petroleum and ethanol extracts exhibited considerable anti-inflammatory activity compared with ketorolac trimethamine as standard.
Anti-Tuberculosis: Study of the volatile oil from the aerial parts of HI showed significant antituberculosis activity against M tuberculosis. The major constituents were phytol, e-dodecanol, and ß-linalool. (4)
Anti-Tumor / Indicine N-Oxide: Extract study yielded an active principle, an N-oxide of the alkaloid indicine, which showed significant activity in several experimental tumor systems. (6)
Anti-Proliferative: One of nine Thai medicinal plants studied on human breast adenocarcinoma cell line; all extracts showed IC50 in the potential range for activity against cancer cells.
(7)
Immunostimulant Effect: Dried leaves extract significantly increased in vitro phagocytic index and lymphyocyte viability in all assays, increase in antibody titer and delayed-type hypersensitivity in mice. Results conclude a dose-dependent immunostimulant effect, probably due to the alkaloid content or combination of other components. (10)
Gastroprotective Effect: Phytochemical analysis yielded alkaloid, saponins and tannins. A gastroprotective function is through its ability to mobilize endogenous prostaglandins in the gastric mucosa, and may be in part due to tannins and saponin constituents. (11)
Repellent Effect: In a search for insecticides and antifeedants of plant origin against Utetheisa pulchella, H indicum killed 56% of the young larvae but did not affect fifth- and sixth-instar larvae. (12)
Antimicrobial / Phytochemical Screening: Antimicrobial screening of various extracts of aerial parts showed significant zones of inhibition against 70% of the test organisms. Extracts yielded alkaloids, saponins, tannins, glycosides, and flavonoids while phobotamins, steroids, coumarin, and cardiac glycosides were absent in all the crude extracts. (15)
Analgesic / Stem: Study of hydroalcoholic extract of the stem of H. indicum in a hot plate model showed significant analgesic effect compared to the standard drug Diclofenac. (16)
Antimicrobial: Study evaluated an alcoholic extract of H. indicum for antimicrobial activity against four strains each of Gram positive and Gram negative bacteria, and three strains of fungi and two yeast. Results showed dose-dependent antimicrobial activity to all the test organisms. (20)
Immune Function Activity / Leaves: Study evaluated the immunostimulatory activity of H. indicum in invitro and in vivo experimental models. Dried leaves significantly increased the in vitro phagocytic index and lymphocyte viability in all assays. It also showed an increase in antibody titer, carbon clearance, and delayed type hypersensitivity in mice. In conclusion, H. indicum showed dose-dependent immunostimulant effect, whhich may be attributed to the alkaloid content or combination of components. (21)

Toxicity concern
Pyrrolizidine alkaloids (PAs) is found virtually in all plants in the Boraginaceae family. PAs have been shown to cause toxic reactions in humans, primarily veno-occlusive disease, when taken as herbal medicine or with food. It has also believed to cause liver damage. (9)

Availability
