Effective Home Treatments & Natural Remedies for Shingles

Our young daughter-in-law just came down with painful shingles. I've forwarded your recommendations (prayers she puts some to use). I've been hesitant to have the shingles shot due to low immunity. Are there any suggestions to KEEP FROM getting shingles? My mom said that as an infant, my older sister and brother brought chicken pox home from school, but I never had any symptoms/rash/blisters. She even took me to the doctor to make sure!
