Dog motion sickness

I have tried the individual Bach Remedy Scleranthus and had it work for motion sickness in the car. I was looking on line for a link and saw that you can use Rescue Remedy also. I went and found the book I have that has a dog section in it. I just wanted to double check that it was Scleranthus for sure.

I have two books that are invaluable regarding the Bach Remedies.
Practical Uses and Applications of the Bach Flower Emotional Remedies by Jessica Bear.
Bach Flower Remedies for Animals by Helen Graham and Gregory Vlamis
