For an average size pony (13 hands high) the daily amount is 25 - 30 grams of dried herbs. Larger horses (16 hands high) require between 30 - 50 grams daily. Exact measurements are not as critical as with synthetic medicines so quantities can be adjusted to suit the size and sensitivity of your horse.
With the liquid extracts, the dosage rates are as follows
5-10 mls daily for 13.2 HH,
20 mls daily for 13.2 HH- 15.2 HH,
30 mls daily for 15.2 HH upwards. 500 ml and 1 litre bottles have a built in chamber for easy measuring.
