Many people think the same internal actions and effects can be experienced from a plant whether as a flower, oil, herb or food when ingested.
However, this is simply not true.
Unlike the subtle aroma of a particular aromatic plant its specific chemical compounds, properties, actions and effects whether a plant, herb, flower or essential oil may be distinctly different from one another even though their aromatic scent may indicate otherwise.
There is some cross over with uses, but sometimes an herb would be better for promoting balance and supporting healing while at other times it would be best to use the whole food.
Generally the best results are obtained with flowers and essential oils when directly inhaled or infused in a carrier oil for topical application.
