- Slight natural batch-to-batch variation in shade is normal for a natural herbal oil and does not affect aroma or performance
- The deeper amber color signals high ligustilide content — a positive quality indicator for Dang Gui oil
- Cold-weather thickening or haziness may appear at low temperatures; warming gently to 20–30°C restores the mobile liquid state
