Are there scientific studies that prove the medical effectiveness of Camellia sinensis?
Yes, there are several scientific studies that prove the medicianl effectiveness of Camellia sinensis. Here are some studies that are worthy of notice.
According to a study published by Journal of Biological Regulators and Homeostatic Agents, the extracts of Camellia sinensis exhibited significant antioxidant potential, with the highest phenolic and flavonoid content recorded. The total phenolic content of the 80% ethanolic fraction of Camellia sinensis was found to be 1456.26±12.05 mg gallic acid, indicating a high level of antioxidant activity. Additionally, the methanolic (50%) extract of Camellia sinensis showed a significant radical scavenging capacity, with an antioxidant capacity of 78.95±7.12% in the DPPH assay.
In another study published by "World journal of plastic surgery", the Camellia sinensis extract has shown antioxidant and anti-inflammatory properties, which may provide a protective effect against skin damage. However, the study found that a 5% extract of Camellia sinensis did not significantly aid in the healing process of skin wounds in rats. Despite this, the extract did exhibit some positive effects, including increased neo-vascularization in the treated group.
A different research published by Animal Cells and Systems, Camellia sinensis extract has been found to have a positive effect on reducing allergic asthma symptoms. It does this by decreasing airway hyperresponsiveness, OVA-specific immunoglobulin E levels, and inflammatory cell and cytokine levels in mice. Additionally, Camellia sinensis extract has been shown to decrease inflammatory cell infiltration and mucus production in lung tissue, and inhibit the expression of matrix-metalloproteinase (MMP)-9 and phosphorylated NF-κB.
