I am surely a Burdock evangelist. Those plants which are now in their second spring go through a selection process right now, still early spring here in New York City, USA. Burdock is a biennial, so it reaches full maturity at the end of it’s second year of growth. Each healthy plant then begins to send up a mighty flower stalk from the center of the plant. All docks grow from a basal whorl – basically a circular arrangement of leaves growing close to the soil.
So the selection decision is between whether to harvest the root in the spring or wait until autumn and harvest the seed. Both parts are powerful medicines. If the plant is allowed to continue to grow throughout the summer it’s root will be consumed in order to produce flowers and seed. I generally only need one large Burdock plant to go to seed. From that one plant I will harvest all the seed for next year’s planting as well as enough for two pints of Burdock seed tincture.
Most of the Burdock I grow will be harvested for the roots. These are chopped first with pruning shears and then shredded in a blender with a little water and tinctured 1:2 (wt. of root: vol. of menstruum) at 45% ethanol.
I’ll get into the details of why Burdock is one of the most important medicinal herbs in another post. Gut and liver health is what I cherish Burdock for so it’s value will depend upon the user. Many herbalists say it’s a “blood purifier” which upsets many medical pros since technically – no it doesn’t. What does purify blood is the liver and Burdock acts upon the liver to support and enhance it’s proper function. It also supports all the beneficial gut bacteria which are the prime agents of good health.
