Rescue remedy is for times of great (more acute) stress...the five flowers in it address shock, loss of control, trauma, fright and disassociation basically. It's not really for the "anger" kind of stress. Cherry Plum (found in RR) is for loss of control, thinking thoughts that are outside the range of normal (like you want to drive off a cliff) and the like. Helpful in that situation, but not entirely what you need.
Beech is for that punitive, judgmental, noone can do anything right kind of place.
Holly is for rage, hatred, jealousy.
Chicory is kind of a manipulative, you owe me kind of feeling. It's described as the "needy mother" the one that is always finding ways to make everyone else feel badly under the guise of doing it for their own good.
Willow is resentment. Great for mothers who tire of doing everything for everyone else with no thanks. Also for moms who have to eliminate foods for nurslings, can't live the lives they want because of their kids...etc.
Vine is controlling, hateful, punitive, unreasonable...kind of an evil stepmother remedy. Takes pleasure in hurting others. Kind of chokes the life out of those around them.
Heather is a self centered, everything that is happening is about me deal...goes VERY well with several others.
You can just put two drops of each (you can use up to 7 at once) in a bottle of water and sip throughout the course of the day. You can also get a little mixing bottle and put 2 drops of each in spring water and take that as often as you think of it. I also encourage people to add them to their bathwater.
Happy healing!
