My husband walked with the Boy Scouts on a sixty-mile trek up a mountain carrying a fifty-pound pack on his back. When he returned, his big toe and second toe on one foot were blue and throbbing. He said he would need to go to the doctor in the morning because he could not bear to wear a shoe over his toes. I looked up bruising in my Essential Oils Desk Reference and decided to try some hyssop oil. Although my husband thought this was not going to be useful, he allowed me to put the oil on his toes in the evening and again at bedtime. He was amazed in the morning that the toes were pink, and they no longer hurt. He never had to go to the doctor.
