Spirulina Tablets Treat Liver Fibrosis/Cirrhosis

Spirulina (Spirulina platensis, SP) is a nutrient-rich blue-green algae that has been widely studied and applied in various health fields. Its main components include spirulina polysaccharide proteins, amino acids, vitamins, and minerals, especially the eight essential amino acids that the human body cannot synthesize on its own. Spirulina is also rich in minerals such as iron, calcium, and zinc, which makes it beneficial in the prevention and treatment of several diseases. Research has shown that spirulina has potential therapeutic effects in combating tumors, obesity, diabetes, cardiovascular diseases, and anemia. In 2020, the National Health Commission of the People's Republic of China classified it as a health food supplement.

Hepatic fibrosis (HF) is a process of chronic liver disease caused by excessive repair responses to liver tissue injury due to various factors. As the fibrosis progresses, extracellular matrix in the liver accumulates, forming scar tissue that gradually replaces the normal liver parenchyma. Eventually, these pathological changes can lead to cirrhosis, portal hypertension, and even primary hepatocellular carcinoma (HCC), which may result in liver failure. Therefore, hepatic fibrosis is considered a critical precursor to cirrhosis and liver cancer.

In 2007, Elsharkawy and colleagues proposed the "hepatitis-fibrosis-liver cancer axis" theory, which emphasized that timely treatment of hepatic fibrosis is crucial to controlling the development of cirrhosis and liver cancer. However, modern medicine has yet to discover specific drugs for treating hepatic fibrosis or cirrhosis. The etiology of hepatic fibrosis is complex, involving various cellular and molecular mechanisms, thus making the in-depth study of its pathogenesis and the development of new treatments particularly urgent.

As the understanding of hepatic fibrosis continues to deepen, increasing attention is being given to the potential of natural products or health supplements in preventing and treating hepatic fibrosis. Spirulina, as a natural product with multiple biological activities, may become a promising direction for exploring new treatments for hepatic fibrosis due to its immune-regulating, antioxidant, and anti-inflammatory effects. Through further clinical and experimental research, spirulina may offer a new complementary treatment option for hepatic fibrosis.
