- Native to Madagascar.
- Introduced to the Philippines after WWII.
- Grows well in the Baguio area; cultivated as ornamental plant.
- Study of ethanolic extract for secondary metabolites isolated 14 compounds: α-amyrin acetate (1), friedelin (2), glutinol (3), 1-dotriacontanol (4), phytol (5),Stigmasta-7,25-dien-3β-ol (6), β-sitosterol (7), Isorhamnetin (8), 2,3-dihydroxypropyl tetradecanoate (9), Eriodictyol (10), Gallic acid (11), quercetin (12), kampferol-3-O-Rutinoside (13) and isovitexin (14). (see study below) (3)
• No reported folkloric medicinal use in the Philippines.
• Antioxidant / Cytotoxic / Antimicrobial: An ethyl acetate fraction showed the most potent radical scavenging on DPPH assay. The n-butanol fraction exhibited the highest cytotoxic activity against tested cell lines. Different crude extracts showed varying antimicrobial activity against most of the specific organisms tested. (see constituents above) (3)
• A blog reports all plant parts are poisonous if ingested.
• When tested for toxicity on 2-week old Leghorn chicks, Kalanchoe tomentosa, K tomentosa X K beharensis, and 4 cultivars of K blossfeldiana were nontoxic at the highest dosage levels tested. (1)
