作者： juyan zhang Cui zhang Department of Microbiology and Immunology Guangdong Pharmaceutical University Guangzhou China

Researchers have proven the Litchi seeds of possessing salutary pharmacodynamic effects, such as dispelling cold, relieving pain, promoting the circulation of qi, and removing stasis. This has resulted in its categorization as an affinal drug and diet in the traditional Chinese medicine. Important research progress has been obtained on the chemical components, traditional pharmacological effects, antivirus and antitumor effects, their molecular mechanisms and immune effects of litchi seeds in recent years. In this review, we have focused on the antitumorrelated effects and mechanisms for the purpose of better utilization and comprehensive understanding of litchi seeds.
