Arnica is about to become your BFF, with better staying power than Paris or any other schleb. 😂
Arnica is a herbal / homeopathic remedy that assists with the dissipation of bruising and healing soft tissue.
It can also help with bone injuries too, I took it when I fractured my radial head (ball joint in elbow).
Taken internally as tablets or drops, or as a cream externally, or both in acute cases, it will help with the healing from bruises, strains, sprains, dislocations and breaks.
It's our first line of defense at the studio, whenever anyone is injured, we give them 2 arnica tablets and at the end of class, they get cream to rub on the injury.
Try a health food shop or pharmacy / chemist / drugstore for it.
