Here is an interesting video, http://www.abc.net.au/landline/content/2015/s4193258.htm, about Manuka honey, which is produced in New Zealand, and Australia, from the Manuka tree, Leptospermum scoparium. The Manuka tree is also called a Tea Tree, and is a small tree, or bush. The honey produced from it is said to have superior antimicrobial properties, often used in the treatment of antibiotic resistant wounds, and as a result is in very high demand, and brings an extremely high price, as much as $125 per pound. However, in recent years there has been a problem with counterfeit Manuka honey. It has been said that there is two, or three, times the amount of Manuka honey sold, versus what is produced.
In Australia there is a another honey in Australia, Jellybush honey, that has similar properties. Here is a follow-up video about this crop, http://www.abc.net.au/landline/content/2015/s4401734.htm
