The protection of the liver as an essential organ in the body against oxidative stress and deleterious compounds has been the subject of recent investigations. Among different compounds, medicinal plants play an important role due to their hepatoprotective effects. Taraxacum officinale or common dandelion is a popular plant that has been traditionally used for its hepatoprotective effects. Currently, there are limited clinical studies on its hepatoprotective effects. The aim of this review article is to evaluate the hepatoprotective effects of dandelion and its mechanism of action. We reviewed literature up to July 2019 on Taraxacum officinale or dandelionand hepatoprotection. Currently available pharmacological studies indicate that dandelion extracts have hepatoprotective effects against chemical agents due to its antioxidant and anti-inflammatory activities. The anti-inflammatory effects of dandelion, the prebiotic effects of its oligofructans, inhibitory effects against the release of lipopolysaccharides and fasting induced adipose factor, digestive enzymes, and enhancing effects of lipogenesis, reduce lipid accumulation and liver inflammation, which directly or indirectly improve the liver functions. Given emerging evidence on hepatoprotective effects of dandelion, designing large human clinical studies is essential.
