Use about a teaspoonful (about 2g) of loose herbs per cup of tea. Place the herbs in your chosen jug or pot (an empty jam jar works fine). Heat can also reduce the quality of the vitamins, so when you make your infusion, pour water that has just off the boil over your herbs. Let the herbs steep for at least 5 minutes, to bring out the delicate flavours and therapeutic nutrients. It's even fine to let your tea steep all day! If you have a lid on top of your cup, this can minimise the loss of the volatile oils.
Avoid using a metal mesh strainer to strain your tea, or a metal spoon to add honey or to stir your tea. Use plastic or better still, wooden implements, such as the Long handled teaspoon and Bamboo Tea Strainer
