Sadly, too many gardeners fail to take advantage of the many delightful herbal teas available to them from their own garden. Herbal teas are healthy, refreshing and can be sweetened to taste with honey or dried licorice root.n Brewing herbal teas is very simple. We recommend using the infusing method, that is pouring boiling water over the herbs and allowing them to steep for 3-5 minutes, then straining the tea and serve. Teas can be served cold or hot, according to preference.
