Platycladus Orientalis: TCM Benefits & Science

Platycladus orientalis (侧柏叶), or Oriental Arborvitae, is a cornerstone of Traditional Chinese Medicine (TCM). Modern studies now confirm its benefits for hair, skin, and inflammation. Let’s dive into its history, science, and uses.

Traditional Uses in TCM

For 2,000+ years, Cebaiye (侧柏叶) has been used to:

• 💧 Cool “heat” conditions like acne and rashes
• 🩸 Stop bleeding (nosebleeds, menstrual excess)
• 🌱 Reverse hair loss and premature graying

TCM practitioners attribute its power to balancing qi (vital energy) and detoxifying the liver-lung axis.

Proven Scientific Benefits

1. Stimulates Hair Growth

A 2020 study in the Journal of Ethnopharmacology found its flavonoids boost scalp circulation by 27% and block DHT (a hair loss trigger).

2. Fights Bacteria & Inflammation

Its essential oils show 99% inhibition against Staphylococcus aureus in this NIH-funded study (2019).

3. Rich in Antioxidants

Contains polyphenols that combat free radicals – linked to slower aging in this 2020 molecular study.
