Oriental arborvitae (Platycladus orientalis), also known as Chinese thuja, has a long history of use in Traditional Chinese Medicine (TCM), including in the treatment of wounds and abrasions. The seeds, leaves, and sometimes the cones of the plant have been applied topically or used in decoctions for their purported astringent, antimicrobial, and wound-healing properties. Historical texts and TCM pharmacopeias mention its use to stop bleeding and promote the healing of minor cuts and abrasions. The traditional rationale is that oriental arborvitae is believed to "cool the blood" and "stop bleeding," making it suitable for superficial skin injuries.

However, modern scientific evidence supporting these uses is limited. Some in vitro and animal studies have suggested that extracts from Platycladus orientalis possess antimicrobial and anti-inflammatory properties, which could theoretically benefit wound healing. For example, certain bioactive compounds isolated from the plant have shown antibacterial effects, and there’s some evidence of anti-inflammatory activity. Despite these findings, there are no robust clinical trials or high-quality human studies specifically validating its efficacy for treating abrasions.

In summary, the use of oriental arborvitae for abrasions is primarily justified by traditional use and historical precedent, with only modest scientific evidence suggesting potential beneficial effects. Until more rigorous clinical studies are conducted, its use for abrasions should be considered as complementary and not as a primary or evidence-based therapy.
