World Par-Tea has blended a 100% Aussie Bush Blend in conjunction with the koala trail… a superb blend of Australian Daintree tea, Organic Hawthorn Berries, Australian Lemon Myrtle and Eucalyptus leaves. For colds and flues there's no better remedy than eucalyptus. Eucalyptus is anti-viral and anti-bacterial and may help with bronchial problems. Good for young and old. Maybe purchased in a 100g or 50g resealable packet or stainless steel tin with inner seal for freshness.
