'''Talisapatra''' (Latin: ''Abies webbiana'' Lindl., synonym: ''Abies spectabilis'' (D.Don) Spach; family: Pinaceae) is a lofty, evergreen coniferous tree native to the high-altitude Himalayan belt. In [[Ayurveda]], its aromatic leaves are regarded as a premier natural expectorant, bronchodilator, carminative, and Kapha-Vata pacifying medicine, famously constituting the primary bio-enhancer and botanical cornerstone of ''Talisadi Churna''.<ref name=" | '''Talisapatra''' (Latin: ''Abies webbiana'' Lindl., synonym: ''Abies spectabilis'' (D.Don) Spach; family: Pinaceae) is a lofty, evergreen coniferous tree native to the high-altitude Himalayan belt.
