It takes weeks to make, but it is worth the work, and I will post it! It is called knit bone, (in latin) syphitum officinalis, or sometimes...bone knit.

Here are my notes on Comfrey (kind of rough info):

Comfrey Knit bone (in latin) syphitum officinalis
allintoin is the active ingredient
volnerary (accelerates healing) a cell proliferant
stimulates cell division and decreases healing time
Stimulates hyaluronic acid which is the mortar the body uses to bind cells together
Smaller scars once healed
expectorant
muscillage content high (GI problem, ulcer healing)
burns
bladder irritation
wounds
internal use is relatively safe.
Easy to grow and spreads (russian comfrey is easier to contain)

Symphytum officinale-Common use: tea for temporary bone, cartilage, tendon and muscle discomfort, as well as to soothe irritated skin, prevent infection and relieve pain.
