Botany
Malabago is a much branched tree, 4 to 12 meters high. Leaves are suborbicular, 10 to 15 centimeters long, green, smooth and shining on the upper surface, grayish and hairy on the under surface, with a pointed tip and heart-shaped base, and minutely toothed margins. Sepals are hairy, 5 in number, oblong and about 2 centimeters long. Petals are yellow, dark purple at the inside base, orbicular-obovate or rounded, about 5 centimeters in length and width. Capsules are hairy, ovoid, 1.5 centimeters long, surrounded by persistent sepals and, at the base, by the bracteolar cup, falsely 10-celled, and 5-valved.

Study Findings
• Antitumor Activity / Roots:Study of antitumor activity of the roots of Hibiscus tiliaceus against Dalton’s ascitic lymphoma in mice showed a significant enhancement of survival time with inhibition of tumor cell growth.
• Antioxidant / Antimutagenic / Flowers: Study on the methanolic flower extract of HT showed the a clear antioxidant activity, attributed to vitamins and phytosterols. Extract also showed significant antimutagenic action against oxidative mutagens in S cerevisiae.
• Antioxidant / Flowers:Aqueous flower extract of H tiliaceus exhibited significant reducing power and free radical scavenging. The antioxidant activities were concentration dependent. The total phenolic content were gallic acid equivalents and the total flavonoids as catechin equivalents.
• Antiproliferative / Cytotoxicity: Study showed the acetone extract of HS exhibited better cytotoxic effect on lung cancer cells than the methanol and water extract. Results show HS-AE exerts significant dose-dependent anti-proliferative effect on cancer cells in vitro and in vivo.
• Antinociceptive / Anti-Inflammatory: Study on the different leaf extracts of H tiliaceus showed significant anti-inflammatory activity and antinociceptive activity on two types of noxious stimuli.
• Antimutagenic / Antigenotoxic: Study showed the methanolic extract strongly inhibited the mutagenic action of hydrogen peroxide and tert-butyl-hydroperoxide. Results showed antioxidant activity and both antigenotoxic and antimutagenic effects against oxidative DNA damage.
• Antioxidant / Antityrosinase: The flowers and leaves of six Hibiscus species were studies for antioxidant, antityrosinase and antibacterial activities. The leaves and flowers of H. tiliaceus showed outstanding antioxidant property. Leaves of TH had the strongest antityrosinase activity. Results suggest HT have the potential for development into functional food and skin care products.
• Hibiscus Yarn: Study evaluated the characteristics and properties of Hibiscus tiliaceus fiber of different ages. Results showed the 4-month H. tiliaceus fiber could produce the smallest and longest yarn (45 meters) while the 3-month yarn had the highest average strength (111.39 N). The differences on physical properties of fiber and yarn of different ages were statistically significant at level of 0.5.
• Immunomodulatory / Leaves: Study evaluated the immunomodulatory effect of a methanolic leaf extract of H. tiliaceus in pyrogallol induced immunosuppressed Wistar rats. Oral administration of the MLHT showed dose-dependent immunomodulatory effect in Wistar rats with significant effect on both humoral and cellular immunity. The results may be attributed to the polyphenols and flavonoid content of the extract.
• Antiulcer / Leaves: Study evaluated fresh leaf extracts of H. tiliaceus for anti-ulcer activity in albino rats. Results showed pretreatment of extract showed significant reduction in lesion index, total area affected and percentage of lesion in cold restraint stress-induced and pylorus ligation ulcer models.
• Anti-inflammatory / Wood / Safety Study: Study evaluated the anti-inflammatory activity of a methanolic wood extract in experimental acute and chronic inflammatory animal models. Results showed dose-dependent significant results with the 200 and 4000 mg/kg body weight extracts. The acute toxicity study showed the methanolic extract of plant wood to be safe up to 200 mg/kbw.
• Antidiabetic / Hypolipidemic / Flowers: Study evaluated the antidiabetic and hypolipidemic activities of a methanolic extract of flowers of H. tiliaceus in STZ-induced diabetic wistar rats. Results showed antidiabetic activity with significant improvement in body weight. There was also significant reduction of serum cholesterol and triglycerides, with improvement of HDL levels.
• Antidepressant / Flowers: Study evaluated a methanol flower extract of HT for antidepressant, anxiolytic, and sedative effects in animal models. Results showed an antidepressant-like action without sedative side effect.
• Antioxidant / Anti-Tyrosinase / Flowers: In a study of leaves and flowers of selected Hisbiscus species, the leaves and flowers of H. tiliaceus showed outstanding antioxidant property. The leaves showed the strongest antityrosinase activity. The AOP and AT activities suggest potentials for used in functional food and skin care products.
