Relaxing, calming, anti-inflammatory
The leaf and twig oil from Combava, or Kaffir Lime (Citrus hystrix), has a bright, fresh, tart aroma, similar to Lime (Citrus aurantifolia). The predominance of the aldehyde, citronellal, supports its use as an anti-inflammatory and antidepressant, to relax and calm.
