Nettles are high in minerals and vitamins, too.
The rash that occurs after being stung by nettles happens within minutes of contact.
Stinging nettles are especially good for treating hay fever with its bothersome watery eyes and sneezing.
If you are diabetic or if you take anticoagulants, blood pressure medication or diuretics, you should discuss nettles with your doctor before you use this supplement.
Young nettles, grass cuttings and comfrey are good natural activators.
