Gen info
- Pseudognophalium luteoalbum is a species of flowering plant in the family Asteraceae.
- Members of the genus are commonly called cudweeds.
-
The species was first published by Carl Linnaeus in his 1753 Species Plantarum, under the name Gnaphalium luteo-album. In 1829, Ludwig Reichenbach transferred it to Helichrysum, but not taken up, and was retained in Gnaphalium until 1981, when Olive Mary Hilliard and Brian Laurence Burtt transferred it into Pseudognophalium. (13)
- Etymology: The specific epithet luteoalbum derives from Latin, meaning "pale yellow". (13)

Botany
• Badok is a woolly, extremely variable annual herb, 10 to 40 centimeters in height. Leaves are woolly 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 ribbed or tubercled and have minute curved bristles.

•  Annual herb to 50 cm tall, all parts whitish-woolly. Stems usually several from the base, decumbent at first, later erect. Leaves sessile, up to 8 × 1 cm at base, oblanceolate, becoming smaller and lanceolate or linear above, greyish or whitish tomentose or arachnoid, on both sides; margin entire. Inflorescence consisting of dense clusters of capitula 1-several together in terminal corymbs. Involucres 3-4 mm in diameter; phyllaries in c. 3 rows, pale brown to whitish. Outer female florets very numerous, whitish. Bisexual disk florets cylindric. Achenes ellipsoid, papillose. Pappus of numerous soft bristles. (Flora of Zimbabwe)

Distribution
- Native to the Philippines.
- In open places, along trails, sunny places, talus slopes, etc; chiefly at medium altitudes, ascending to 2,400 meters.
- In Ifugao, Lepanto, Bontoc, Benguet Subprovinces; in Cagayan, Pangasinan and the Camarines Provinces in Luzon.
- Also native to 
Afghanistan, Albania, Algeria, Angola, Assam, Austria, Azores, Baleares, Baltic States, Bangladesh, Belarus, Belgium, Benin, Botswana, Bulgaria, Burkina, Cameroon, Canary Is., Cape Provinces, Cape Verde, Central African Republic, Central European Russia, Chad, China North-Central, China South-Central, China Southeast, Corse, Cyprus, Czechoslovakia, Denmark, East Aegean Is., Egypt, Eritrea, Ethiopia, France, Free State, Germany, Great Britain, Greece, Guinea, Gulf of Guinea Is., Gulf States, Hainan, Hungary, India, Iran, Iraq, Italy, Jawa, Kazakhstan, Kenya, Kriti, KwaZulu-Natal, Laos, Lebanon-Syria, Lesotho, Libya, Madagascar, Madeira, Mali, Mauritania, Mauritius, Morocco, Mozambique, Myanmar, Namibia, Netherlands, New Caledonia, New Guinea, New South Wales, North Caucasus, Northern Provinces, Northern Territory, Oman, Pakistan, Palestine, Poland, Portugal, Queensland, Romania, Réunion, Sardegna, Saudi Arabia, Senegal, Sicilia, Sinai, South Australia, South European Russia, Spain, Sudan, Swaziland, Sweden, Switzerland, Tadzhikistan, Taiwan, Tasmania, Transcaucasus, Tubuai Is., Tunisia, Turkey, Turkey-in-Europe, Turkmenistan, Ukraine, Uzbekistan, Victoria, Vietnam, West Himalaya, Western Australia, Yemen, Yugoslavia, Zambia, Zimbabwe. (7)

Properties
- Leaves considered astringent, cholagogue, diuretic, febrifuge, hemostatic and vulnerary.

- Studies have suggested antiseptic, antifungal, cytotoxicity, antioxidant properties.

Constituents
- 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) (1) and stigmasterol-3-O-β-glucopyranoside (2).
(See study below) (6)
- Phytochemical screening of the plant revealed alkaloids, carbohydrates, phenols, saponins, flavonoids, tannins, glucoside resins, phytosterins, terpenoids and fixed oils. (9)
- Three flavonols, structurally related to each other, were isolated from leaves: gnaphaliin, calycopterin and 3’-Methoxycalycopterin. Chlorophyll a and b and carotenoid were also isolated from the leaves. (9)
- GC and GC/MS analysis for essential oil yielded 44 compounds, representing 70.6% of total oil with 4.4% monterpene hydrocarbons, 5.0% oxygenated monoterpenes, 14.7% sesquiterpene hydrocarbons, 3.6% oxygenated sesquiterpenes, 29.1% aliphatic compounds, 10.4% fatty acids and esters, and 3.4% others. Main constituents were decanal (9.7%), ß-caryophyllene (8.0%), and α-gurjunene (6.4%). (9)

Parts used
Leaves.

Uses

Edibility
- Leaves, raw or cooked. (10)
- In Vietnam, the plant is used as plant ingredient, as in the rice cake banh khuc. (13)

Folkloric
- In the Punjab, leaves are used as vulnerary and astringent.
- In Pakistan, used as anti-diarrheal; infusion of aerial parts used as emmenagogue. Used by the Kavirajes of Chalna as tonic, and for tumor, gout, and dermatitis. In Belgium, used for treatment of cancer. (9)
- 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.
(3)
- In Nigerian folk medicine used as antiabortive, cyanogenetic, demulcent, diuretic, emollient, intoxicant, blood tonic. Also used for treatment of cancer, epilepsy, flux, stomach ache, and malaria.
- In Pakistan, leaves used for treatment of asthma and breathing disorders. (14)
Others
- Tinder: Leaves used as tinder. (10)
- Fodder: Leaves used as fodder. (12)
- Ethnoveterinary: In Angola, leaves used in contagious pleuropneumonia in cattle and goats. (12)

Studies
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. (4)
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. (see constituents above) (6)
• Cytotoxicity / Leaves: Study evaluated the cytotoxic activity of crude methanol extract of leaves against healthy mouse fibroblasts (NIH3T3), healthy monkey kidney (VERO), and four human cancer cell lines (gastric, AGS, colon, HT-29, and breast MCF-7 and MDAMB-231) using MTT assay. Results showed high cytotoxicity against AGS and MCF cell lines with IC50 0.98 and 0.34 mg/ml respectively. (9)

•  Antioxidant / Aerial Parts: Study evaluated the antioxidant potential of crude methanol extract and various fractions of aerial parts. Phytochemical screening of aerial parts confirmed the presence of carbohydrates, phenols, flavonoids, and saponins in the crude extract and all fractions.  The crude methanol extract (CME) showed highest scavenging activity (43.28%) with IC50 of 398.49 µg/mL in the DPPH radical scavenging assay. CME showed highest TPC (total phenolic content) of 115.96 mg of gallic acid equivalent/g of dried extract. Results suggest CME of aerial parts can be used as natural source of antioxidants for prevention and slowing of oxidative stress related disorders. (15)

The compilation now numbers over 1,500 medicinal plants. While I believe there are hundreds more that can be added to the collection, they are becoming more difficult to find. If you have a plant to suggest for inclusion, native or introduced, please email the info: scientific name (most helpful), local plant name (if known), any known folkloric medicinal use, and, if possible, a photo. Your help will be greatly appreciated.
