Health Benefits of Tamanu Oil

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Tamanu oil, derived from the fruit and seeds of the Calophyllum inophyllum tree, has been traditionally used for its therapeutic properties. Recent scientific studies have begun to validate its efficacy, particularly in skin health and wound healing. This article explores the health benefits of Tamanu oil, focusing on its role in inhibiting photoaging and promoting wound healing.

Inhibition of Photoaging

Photoaging, primarily caused by UV-B irradiation, leads to increased expression of matrix metalloproteinase-1 (MMP-1) and subsequent collagen degradation due to the formation of reactive oxygen species (ROS). A study investigated the effects of topical Tamanu oil on male Wistar rats exposed to UV-B radiation. The results demonstrated that Tamanu oil significantly inhibited the increase of MMP-1 expressions and maintained higher collagen levels in the dermis compared to the control group. Specifically, the mean expression of MMP-1 was significantly lower in the Tamanu oil group (22.73±2.68 cell/HPF) compared to the control group (34.03±2.97 cell/HPF). Additionally, the collagen amount was significantly higher in the Tamanu oil group (65.66±8.13%) compared to the control group (38.90±11.64%)1.

Wound Healing Properties

Tamanu oil is also renowned for its wound healing capabilities. A study evaluated its efficacy in treating wounds induced in rats. The study compared the wound healing potential of Tamanu oil with a reference drug, Centella asiatica. The findings revealed that Tamanu oil significantly accelerated wound healing by promoting macrophage infiltration, granulation tissue formation, and fibrosis. On day 7, the Tamanu oil group exhibited higher macrophage infiltration and mature granulation tissues compared to the control group. Furthermore, fibrosis and collagen density were notably higher in the Tamanu oil group, indicating enhanced wound healing2.

Conclusion

Tamanu oil has demonstrated significant health benefits, particularly in skin health. It effectively inhibits photoaging by reducing MMP-1 expressions and maintaining collagen levels. Additionally, it accelerates wound healing by promoting macrophage infiltration, granulation tissue formation, and fibrosis. These findings support the traditional use of Tamanu oil for skin-related ailments and highlight its potential as a therapeutic agent in dermatology.
