hi hexkitten, welcome....

i feel like flower essences are the ultimate in subtle, intuitive, vibrational medicine, so i would trust your intuition and roll with it. working with them in your own garden and making the essences will most likely confirm whether or not your suspicions were accurate. AND i personally also like to check textbook sources too, because i think the collective info gathered is really helpful. also, you may want to have a look at borage and mustard for depression.

i have made my own (just this week we made calendula, cal poppy, yarrow and mustard), and i highly recommend it. it is so fun and super easy and you get to make sure you're putting the specific love and prayers and blessings in there, whereas with storebought, while they work, you just can't guarantee the love at that stage of production. we also added some crystals actually, which we carefully chose to match the flowers. yay. good strong medicine.
