Lavender Essential Oil isn't that bad . It depends abit on the variety you use.Some are very floral others more 'antisepticy'
In France they use a small
angustifoloia variety to make delicious ice cream and ices. (In England this might be called dwarf
Hidcote Lavender).
Lavender oil is also intoxicating if drunk
Many herb Essential oils are used to make flavours (
Coca Cola a famous one) but the strength of the oils makes them too difficult (usually) to use in home cooking.

Growth hormone also guides brain wiring
Anyone want to translate it for me?

Compared to the visual system, the brain's odour system is still poorly understood, but it appears to have its own uniquely ordered connections, Ngai said. The nose contains some 5 million nerve cells, each of which carries only one kind of odour receptor out of about 1,000 different odor receptors, each tuned to detect different chemicals or odorants. Nose nerve cells that detect the same odorant send their axons to the same region of the olfactory bulb, and it appears that neurons that detect similar chemicals, such as different alcohols, send their axons to nearby areas of the bulb.
Scientists previously had discovered that each of our two olfactory bulbs is divided down the middle between two mirror-image representations of the nasal odour receptors. Ngai and his colleagues found that IGF is responsible for setting up these mirror images within the bulb.
"IGF signaling is absolutely required for this mirror symmetry," he said. "In the absence of IGF function, you lose information from the sensory axons of the nose to one half of the bulb."
Airborne scent chemicals (inset) stimulate odor receptors in the nasal cavity, which send signals to the brain's olfactory bulb (yellow) located in the frontal lobe of the brain just above the nasal bone.
These connections are set up during early development when sensory nerves in the nose send axons into the brain (blue and gold) that target specific neurons in the bulb to create a map of sensory information that displays a mirror symmetry across the bulb’s midline (dashed line).
When IGF signaling is disrupted (right), the blue axons collapse toward the bulb’s midline, resulting in a distortion of this sensory map, demonstrating the critical role played by IGF in wiring the brain. (John Ngai/UC Berkeley; inset courtesy Nobel prize committee)
