Coral bush is a shrub growing up to 1 meter, low growing with distinctive drooping flower-laden stems. Leaves are small, linear-lanceolate or ovate and almost scalelike on the branches. Flowers are red, tubular, 2-lipped, up to 3 cm long and in loose branching clusters.
– Native to Mexico.
– Recently introduced to the Philippines.
– Leaves yielded alkaloids, flavonoids, saponins, tannins, steroids, and terpenoids.

– Studies suggest anti-inflammatory, analgesic, antimicrobial, anticonvulsant, antidiabetic properties.
• No known folkloric medicinal use in the Philippines.
• In southwestern Nigeria, used for diabetes and leukemia.
• Used to treat malaria, cancer, and inflammatory diseases.
• Used to promote hair growth.
• Leaf and stem extract of Requisetiformis used as ingredient in cosmetic products.
• Antimicrobial: Antimicrobial effect of a methanolic extract was noted on S. aureus, S. albus, S. typhi, P. aeruginosa and K. edwardsiella. The effect was attributed to triterpenes in the extract.
• Diabetes / Leukemia: Phytochemical Screening of Cnidoscolus Aconitifolius and Russelia Equisetiformis Used for the Treatment of Diabetes and Leukemia.
• Antinociceptive: Results of study of whole plant extracts effect of Russelia equisetiformis confirmed the traditional uses of RE in the treatment of inflammation and pain.
•Antiinflammatory / Analgesic: In a study of the methanolic extract of E equisetiformis in rats and mice using carrageenan-induced rat paw edema, acetic acid-induced writhing and tail-flick testing, results suggested that the extract possesses potential anti-inflammatory and analgesic properties.
• Hair-Growth Promoting Effect: Topical application of the methanol extract of the whole plant of R equisetiformis on a known diameter of shaved area of the back of albino wistar rats produced a significant increase in the rate of hair growth. The hair growth promoting potential is attributed to the presence of triterpenes and flavonoids in the plant extracts.
• Membrane Stabilizing Activity: Study showed the aqueous-ethanol extract of R equisetiformis possess membrane stabilizing activity in a concentration-dependent manner as evidenced by significant changes of membrane stabilization of RBC exposed to heat stress-induced hemolysis.
• Hepatic Function Impairment: Methanol and aqueous extracts of Rusellia equisetiformis were evaluated for effects on hepatic functions. Results showed impairment of liver function with a dose-dependent elevation of enzymes ALT, AST, alkaline phosphatase, with a significant reduction in serum protein. The effects were more pronounced with the methanol extract.
• Antioxidant / Antimicrobial / Cytotoxicity: Study of extract and fractions showed significant antioxidant potential using a DPPH scavenging and linoleic acid oxidation assays. Extracts and fractions also showed antimicrobial activity against selected bacterial and fungal strains. On cytotoxicity testing by hemolytic assay, results showed minor cytotoxicity as percentage lysis of RBCs below 5.0%.
• CNS Depressant Activity: Study of crude methanol extracts of R equisetiformis in mice showed central nervous system depressant activities.
• Anti-Inflammatory: Study isolated lupeol. The lupeol extract showed significant and dose-dependent anti-inflammatory activity in acute and chronic models of inflammation viz egg albumin-induced paw edema, formaldehyde–induced arthritis and cotton pellet granuloma in-vivo tests. Prednisolone was used standard drug.
• Anticonvulsant: Study of methanol extracts of RE for anticonvulsant activity using picrotoxin (PCT) showed significant protective activity against picrotoxin, probably through GABAergic neurotransmission, and/or facilitating GABAergic actio in the brain. Results suggest a potential use as supplementary therapy for management and/or control of childhood convulsions and epilepsy.
