In several Tablets, Baha’u’llah praises medicine and the “science of healing”.  He Himself urged His followers to seek care when they are ill and follow the advice of competent providers, explaining that it is through science and “material means” that God assists humanity-

“Resort ye, in times of sickness, to competent physicians. We have not set aside the use of material means, rather We have confirmed it through this Pen, which God hath made the Dawning place of His shining and glorious Cause.”
