Cypress essential oil
At first glance you would assume that this oil would be a good addition to any asthma-type blend. However further research indicates that at higher concentrations the inhaled essential oil can be an irritant and should be used with caution and knowledge if using for asthma or COPD (chronic obstructive pulmonary disease.)
Avoid with estrogen dependent cancers, avoid if pregnant and some sources recommend to avoid with hypertension (high blood pressure.) Otherwise, non-toxic, non-irritant or non-sensitizing to the skin. Always use essential oils diluted with carrier oil or other pertinent ingredients.
