Which Lavender should I choose?
Lavender officinalis often called lavender 40/42 is the Lavender of choice for making products such as soaps, perfumes, and candles. The 40/42 refers to the balance of Linalool and Linalyl in the oil. These levels are reached by mixing batches of Lavender oil together to get the right ratio.
This gives Lavender officinalis a stronger aroma that is consistent from batch to batch. It also means Lavender 40/42 is considered a standardized oil rather than a pure oil. So while it is still a therapeutic Lavender it is regarded as less therapeutic than other varieties.
Lavender angustifolia is the more therapeutic Lavender. It has a softer, prettier smell than the officinalis.
