Alambrillo is a slow-growing evergreen fern
with a short, ascending, and scaly rhizome with spirally arranged, stipitate
and compound leaves. Stipes are suberect and rather slender, 10 to 20 centimeters long, polished and dark green. Fronds are bipinnate, with a short terminal pinna and numerous erect lateral ones on each side; the segments (pinnae) are 1 to 2.5 centimeters broad, the base being cuneate and the outer edge rounded. Sori are roundish, situated in the roundish sinuses of the crenations.

- In Ayurveda, Adiantum spp. used for colds, tumors of the liver and spleen
skin diseases, bronchitis and inflammatory diseases.
Study on the aerial part of Salsala rasmarinus and Adiantum capillus
reported the presence of antimicrobial flavonoids. (1) In a study of Adiantum species, A capillus-veneris was next to
A venustum in degree of activity as antimicrobial agent. ACV had very low MIV value against E coli.
• Antibacterial Activity of Essential
Oils : A lemon yellow colored essential oil was extracted
from the leaves of AC which exhibited maximum inhibitory activity against
S typhi; mild antibacterial activity against Pseudomonas species, Klebsiella
pneumoniae and Streptococcus pyogenes. (2)
• Antidiabetic / Metal Content:
Study focused on the hypoglycemic effects and metal contents of plants.
Iron and chromium were found in all anti-diabetic herbs, including A capillus. Water
soluble lead was high in A. capillus. The water extracts of plants were found to be better hypoglycemics than the acid digested part with its higher metal content. Study concluded that the metal
content did not have any particular relation to the antidiabetic effect
of the herbs.
• Antimicrobial / Phenolic Content:
Study of methanolic extracts of Adiantum spp. showed Adiantum capillus-veneris
activity against E. coli, activity probably due to its high phenolic
The water extracts and extracted phenols from gametophytes and sporophytes of two ferns – A capillus-veneris and Adiantum lunulatum were tested for antifungal activities against Aspergillus niger and Rhizopus stolonifer. Activity was found higher in the gametophytes and ACV was found a better antifungal than AL. (7)
• Anti-Inflammatory / Antinociceptive:
Study investigated the anti-inflammatory and anti-nociceptive activities of a crude ethanolic extract and various fractions of Adiantum capillus-veneris in a carrageenan-induced hind paw edema model. Results showed significant analgesic activity comparable to ibuprofen. An anti-inflammatory effect appeared to be due to inhibition of NO release and decrease of TNF-a level. (11)
• Antimicrobial / Functional Compounds:
An EtOAc fraction exhibited broad spectrum antimicrobial activities against all tested microorganisms, especially Candida albicans. Phytochemical study showed the fraction to yield the highest total flavones, total phenolic contents, and characterized various compounds. Observed bioactivities were attributed partly to phenolic acids and flavonoids, especially 3-p-coumaroylquinic acid and kaempferol 3-O-glucoside.
• Antioxidant / Phytochemicals:
Study yielded phenolics and terpenoids (2.73%). fats and waxes (0.20%), alkaloids (0.53%). quaternary and N-oxides (26.33%). and fiber (67.23%). Of ten elements, Ca and K were found at major levels. Results showed the leaves to possess free radical scavenging molecules, with potential use as source of natural antioxidants and nutrients. (14)
• Antioxidant / Phytochemicals:
Study showed crude flavonoids to possess potent antioxidant properties, and presents as a potential source of antioxidants for the medical and food fields. (15)
• Phytochemicals / Anti-Inflammatory / Dried Fronds:
Study of alcoholic extract and fractions of dried fronds yielded four triterpenoidal compounds and three flavonoids. Biologic studies of the extract and fractions showed anti-inflammatory activity. A total alcoholic extract showed significant hypoglycemic activity. (see constituents above) (19)
• Activity Against Testosterone Induced Alopecia:
Androgenetic alopecia is the most common form of hair loss in men. Study evaluated the hair growth promoting activity of a preparation of ACV on albino mice using a testosterone-induced alopecia model. Results showed hair growth potential for A. capillus-veneris formulation for androgenic alopecia and other androgen related disorders. (20)
• Anti-Urolithiasic Effect: Study investigated the anti-urolithiasic effect of a hydroalcoholic extract on calcium oxalate urolithiasis in male Sprague Dawley rats. Results showed significant reduction in number of crystals, with decrease in serum levels of calcium, phosphorus and BUN. (21)
