Homeopath and Practitioner Caroline Putus says:

Bach Flower Remedies are a gentle, natural way to improve emotional balance. They are safe to take and you can’t overdose on them. They are available from supermarkets, Boots and health shops.
As for helping your riding, aspen is a good remedy to help if you get nervous just thinking about being onboard. If you are generally confident but just feeling a bit overwhelmed when riding, then try elm. And if things aren’t going to plan, and you become discouraged and feel like giving up – try gentian.
