Badok is a wooly, extremely variable annual herb, 10 to 40 centimeters in height. Leaves are wooly on both surfaces, linear-spatulate or oblong-spatulate, 2.5 to 5 centimeters long, 0.4 to 1 centimeter wide, and blunt-tipped. Inflorescences are terminal, bearing crowded clusters of glistening, yellow heads. Involucral bracts are oblong. Achenes are tubercled or have minute curved bristles.
– In open places, chiefly at medium altitudes, ascending to 2,400 meters.
– In Ifugao, Lepanto, Bontoc, Benguet Subprovinces; in Cagayan, Pangasinan and the Camarines Provinces in Luzon.
– Native of Europe and Asia.
– Occurs in India to China, Japan and Taiwan, and southward to Borneo.
– Leaves considered astringent, cholagogue, diuretic, febrifuge, hemostatic and vulnerary.
– Study has yielded protective flavonoids, calycopterin and 3′-methoxycalycopterin from the leaf wax.
– Crude extracts yielded 5,4′-dihydroxy-6-methoxy-7-O-β-glucopyranosideflavone (hispidulin-7-O-glucopyranoside) and stigmasterol-3-O-β-glucopyranoside.
– In the Punjab leaves are used as vulnerary and astringent.
– In Pakistan, used as anti-diarrheal.
– Infusion of aerial parts used as emmenagogue.
– Used as a counter-irritant for gout.
– In Bangladesh, plant is used by the Garo tribe, crushed along with dried fish and applied as a poultice to heal fractured bones. Also, used by the Kavirajes of Chalna as tonic, and for tumor, gout, and dermatitis.
• Flavonoids / Antiseptic: Study of aerial parts yielded flavonoid compounds 5, 7, 3, 4 tetrahydroxy flavone; 5, 3, 4 trihydroxy flavonol and 3, 5 dihydroxy flavonol. Flavonoids were investigated as antiseptic against 4 bacterial and 2 pathogenic fungal strains.
• Antifungal: Study of acetone crude extract of leaves showed strong antifungal activity when tested against pathogenic plant fungi in vitro. No cytotoxicity of isolated compounds against Vero kidney cells was observed.
