“…DHA is a naturally occurring tricyclic diterpenic resin acid, which can easily be obtained from Pinus rosin or commercial disproportionated rosin [ 6 ]. Recently, DHA and its derivatives were claimed to possess a wide range of biological and pharmacological activities, such as antiprotozoal [ 7 ], antiulcer [ 8 ], anti-inflammatory [ 9 ], immunomodulatory, antiviral [ 10 ], antimicrobial [ 11 , 12 ], antifungal [ 13 ], anxiolytic [ 14 ], anti-aging [ 15 ], gastroprotective [ 16 ], and BK channel-opening [ 17 ] activities.
