Scientific laws are considered established and universally applicable (to certain class of things or phenomenon under appropriate conditions) but not necessarily definitive. Also called laws of science.
Afflictions of the respiratory system include irritation and infection of the ears, nose and throat. Respiratory problems also may involve congestion, which can be decreased by inhaling rosemary (especially the verbenone type), hyssop (use var. decumbens only), tea tree, eucalyptus, lavender or peppermint.
Peppermint or eucalyptus oil in a humidifier helped open up my nasal passageways and are natural sinus decongestants. If your nose is stuffy, try to dilute 1 drop of Eucalyptus Oil in 1 tbsp of carrier oil and rub it on the bridge of your nose (donât let it touch your eyes though).
