Lignins are major class of natural products present in the natural kingdom, and are formed through phenolic oxidative coupling
process in the plant. Lignin is a multifunctional natural polymer that has the potential to be developed into a major industrial raw material
for multitude of applications. After cellulose and hemicelluloses, lignin is considered to be the most abundant polymer present on planet
earth. Many studies have confirmed the potential application of lignins and related compounds in vivo and in vitro. This paper is a review
of the most significant results present in the literature concerning the biological and pharmacological applications of lignins and related
compounds. The evidence reviewed here will facilitate the identification of what is known in this area, the gaps that exist, and the future
research that holds the most potential and promise to affect the human health.
Keywords: Lignins, Pharmacological application, Oxidative stress, Antiviral, Antitumor, Immunomodulatory.
