Which chamomile-derived compound is known for its deep blue color and soothing properties?

• A. Bisabolol
• B. Azulene
• C. Chamomile Oil
• D. Echinacea

Answer: (B)

Azulene is the chamomile-derived compound known for its deep blue color and soothing properties. The blue hue comes from azulene itself, a distinctive constituent in chamomile essential oil, which also contributes to calming, anti-inflammatory effects on the skin. While another chamomile component, bisabolol, also helps reduce irritation, it is colorless, so it doesn’t explain the blue color. Chamomile oil is the whole extract that contains azulene among many other constituents; the blue coloration and soothing action come specifically from azulene. Echinacea is not derived from chamomile and doesn’t contribute these chamomile-specific properties.
