Agoho is a large, evergreen tree, tall and straight, up to 20 meters high. Crown is narrowly pyramidal, resembling some of the conifers in appearance. Bark is brown and rough. Branchlets are very slender, about 20 centimeters long, mostly deciduous, composed of many joints. Internodes are about 1 centimeter long, somewhat 6- or 8-angled. Flowers are unisexual. Staminate spikes are slender, 1 to 3 centimeters long. Cones are usually ellipsoid, 1 to 2 centimeters long, composed of about 12 rows of achenes enclosed in the hardened bracts.

• Antibacterial: In a study of seven medicinal plants investigated for antibacterial and toxic activities, C. equisetifolia exhibited strong activity against S aureus, B subtilis and S sonnei. Casuarina equisetifolia was one of 12 medicinal plants studied for antibacterial activity against B subtilis, S epidermis, Pseudomonas pseudoalcaligenes, P vulgaris and S typhimurium.
• Hepatoprotective: C. equisetifolia was one for four medicinal plants that showed dose-dependent protection against carbon tetrachloride induced hepatocellular injury in rats.
• Antidiabetic / Hypolipidemic: Study of ethanolic extract showed reduced blood sugar in STZ-induced diabetic rats. There was also a significant reduction in total cholesterol, LDL, VLDL, with an improvement in HDL cholesterol.
• Antioxidant / Antimicrobial / Anti-Aggregating Properties: Study showed the condensed tannins extracted from C. equisetifolia exhibited considerable DPPH radical scavenging activity and ferric reducing antioxidant power. Extracts also showed moderate hemolytic action and potent antimicrobial effect on Bacillus proteus, B. subtilis, K. pneumonia, and Aspergillus fumigatus.
• Antiasthmatic: Study of ethanol extract of bark showed significant dose-dependent antiasthmatic activity in various in vitro and in vivo animal models..
