Hi,
All the herbs recommended by Juliette are safe to use . You can get all the herbs from your local high street herbalist shop for less than 50p (in Wigan). To make an infusion you will need one large handful of the fresh herb (or two heaped tablespoons dry herb ), put the herbs in a pint of cold water, cover well, then simmer until near boiling point, do not boil. Then stand, off heat, to brew for 4 hrs. Do not strain. Pour into a clean jar , covering this with paper ( not waxed ) or cotton cloth against dust, etc. Make a fresh infusion every 3 days, 2 or less days in hot weather.
The dosage is usually 2 level tablespoons of the infusion morning and night, and always at least 30 mins before a meal.
As quoted in Juliettes book "Unlike chemical canine remedies, all herbal medicines are harmless and therefore there is no fear of an overdose."
I hope this helps.
From Karen
