i have no idea, but the first word that came to my mind, was "happiness" :)

Gurudas' _Flower Essences and Vibrational Healing_ says Lilac is good for the spinal column, the posture, and aligning the chakras and the spiritual bodies.

However, although I love reading this book because it makes flower essences sound like panaceas, none of its information so far has resonated with me when I've tried essences with it in mind, and I've not been able to reconcile how different the uses are for the same essences, comparing what this book says to conventional flower essence lines. Could be it's too abstract--I tend to sense emotional changes easily, which lines like Bach work on, but am not so sensitive to things like whether my bodies or chakras are aligned.

For uprightness, lightness; helps those who burden themselves, refusing help from others. This is an abbriviated defintiion from Delta Gardens a very progressive flower essences research center in New Hampshire. The founder David Dalton is doing some amazing work with essences, worth looking into.

Cheers~

i use it for spine problems, it works very well. I mix lilac essence with crystals elixirs. If you are interested i can tell you what crystal elixirs i put into this essence

This question has been bugging me since you first posted... why make a flower essence if you don't know what it's good for???

I have been under the (perhaps misguided) impression that essences are made because their use is already apparent. I didn't know that people went around making essences from whatever, waiting to see if they were useful for something...
Do a lot of people do this? Have many useful essences been discovered this way?

I'm just curious!

I found this from a flower essence website . . . hope it helps.

LILAC
It has been said that lilacs are favoured by angels and extra-terrestrials. In any case, lilac opens ones spiritual connection to higher realms, making communication with other dimensional beings possible; opens and balances the crown and third-eye chakras.

Peace!

I have used it and discovered it helps when letting go of a difficult day.
It is great after a bad day at the office. It helps lift your mood and lighten your outlook on the day.. Much like just sitting near a lilac bush in bloom.

I have some white lilac lotion I love putting it on.
For me it helps me to feel calm and let go of worries and stress.
It uplifts my spirit as well.

I just recently tried Lilac flower essence from Alaskan Essences, and it is awesome! I just posted that it helped me to realign my body energy systems, and I felt it got "out of whack" after a surgery to remove my right ovary and healthy appendix. I have been doing other healing work too, but noticed a big boost! It is also on sale now only if you order it online, and they are wonderful to deal with! :-)
