What is CROWN Plus?
CROWN Plus is the maximum-cooling roller for migraine attacks. The Triple Cool Complex (menthol plus slower, odorless coolants) layered over Bing Pian, Chuan Xiong and Bai Zhi, in a water-free, lavender-free base. It is for the days when regular cooling is not enough. See CROWN Plus.
CROWN or CROWN Plus, which one is for me?
They use different coolants, so the cold feels different. CROWN (menthol and camphor) is the everyday roller for migraine attacks and daily use, and it isn’t just about the cold: magnesium, Bing Pian, Chuan Xiong and German chamomile round it out.
