Specific
Aromatherapy Applications

Pain:
Often applied through massage oils, lotions, liniments, or compresses,
essential oils reduce pain by different mechanisms:

Numbing: Some oils - such as clove bud, frankincense chamomile, lavender,
and lemongrass - dull pain by numbing nerve endings,

Anti-inflammatory:
Oils such as chamomile, geranium, juniper, lavender, marjoram,
myrrh, rose, and tea tree diminish pain through anti-inflammatory
actions.

Heat: Some
oils – e.g., as bay laurel, bay rum, black pepper, cinnamon, clove
bud, ginger, juniper, peppermint, and thyme - relieve pain by producing
heat and increasing circulation.

Brain: Some oils -
such as frankincense, ginger, and lemongrass - interfere with the
brain’s processing of pain signals.

Neurotransmitters:
Oils such as birch (containing aspirin-like compounds), cayenne,
and ginger hinder the production of neurotransmitters that carry pain
messages from nerve endings to the central nervous system.

Relaxation: Using
chamomile, clary sage, lavender, lemon, lemon eucalyptus, lemon verbena,
marjoram, melissa (lemon balm), myrtle, and petitgrain (a citrus-related
plant) may help relieve pain through relaxation.
