- During the middle ages, plant was referred to as the mythical "Vegetable Lamb of Tartary" because of the resemblance of the rhizomes to a lamb. The "lamb" is exposed by removing the leaves from the woolly rhizome, which when inverted fancifully resembles a woolly lamb.
- Borabor is a large terrestrial fern growing to a meter or more in height, covered with dense yellow hairs at the base. Fronds are a meter or two long, ovate, hardly tripinnate and glabrous beneath. Lower pinnae are ovate-lanceolate, 30 to 60 centimeters long. Pinnules are linear-lanceolate. Sori are 2 to 12, rarely one, on each side of the segment. The indusium is brownish.
- Found in the mountains, from Luzon to Mindanao.
- Native to parts of China and the western part of the Malay peninsula.
Extends from Assam across Malaysia.

Results indicate M radix, Cibotium barometz, A cortex, C herba have inducing ability on ALP synthesis on osteoblast. (7)
• Antiosteoporosis Effect/ Ovariectomized-Induced Osteoporosis: Study evaluated the effects of CB extract on ovariectomy-induced osteoporosis in female Sprague-Dawley rats. Results showed the treatment can enhance bone strength and prevent the deterioration of trabecular microarchitecture, and presents a potential alternative for prevention and treatment of postmenopausal osteoporosis. (9)
• Inhibition of SARS-CoV Replication: In a study of more than 200 extracts to evaluate anti-SARS-CoV activities, six herbal extracts, including Cibotium barometz, were found to be potent inhibitors of SARS-CoV. Results suggest a potential for the extracts as candidates for the development of anti-SARS therapeutics. (10)
