Blessed Thistle

Blessed thistle contains chemicals called tannins, which might help with diarrhea, cough, and swelling.

People use blessed thistle for indigestion, infections, wounds, and many other conditions, but there is no good scientific evidence to support these uses.
 
Spiritual : protection, purification, hex-breaking, and healing, except as noted below. Grown in the garden, thistle repels thieves. Kept by the door, it wards off evil.
