Abstract: Healing wounds is an important attempt to keep the internal higher organs safe. Compli-
cations in topical wound healing may lead to the formation of scars, which can affect the patient’s
quality of life. Although several approaches are ongoing in parallel in the exploration of natural
compounds via advanced delivery, in this article, an attempt has been made to highlight tocotrienol.
Tocotrienol is a natural form of vitamin E and has shown its potential in certain pharmacological
activities better than tocopherol. Its antioxidant, anti-inflammatory, cell signal-mediating effects,
angiogenic properties, management of scar, and promotion of wound environment with essential
factors have shown potential in the management of topical wound healing. Therefore, this review has
aimed to focus on recent advances in topical wound healing through the application of tocotrienols.
Challenges in delivering tocotrienols to the topical wound due to its large molecular weight and
higher logP have also been explored using nanotechnological-based carriers, which has made to-
cotrienol a potential tool to facilitate the closure of wounds. Exploration of tocotrienol has also been
made in human volunteers for biopsy wounds; however, the results are yet to be reported. Overall,
based on the current findings in the literature, it could be inferred that tocotrienol would be a viable
alternative to the existing wound dressing components for the management of topical wounds.

1. Introduction
Emerging trends regarding disease-specific molecular alteration at the disease site have
focused on agents for treatments. Topical wound treatment processes to combat diseases have
shown gradual improvement over the years. The concept of Galen, the Greek physician, on
wound healing environments by requiring a moist condition has been widely implemented
during 120–201 AD [1–3]. Outcomes of further research on wound treatment brought an-
other consequence of epithelialization in an occluded environment, where the time to heal
the wound is shorter when the wound healing microenvironment along with the essential
components was maintained, compared to the wounds left open and exposed to the environ-
ment [4,5]. Numerous research in recent years aims to bring novel agents in a new delivery
tool to meet the requirements of ideal dressing [6]. Since the ancient period, exploring nature
