I have recently looked for the manuca plant in order to make tea from the leaves, as I'm told it is good for you, yet there are so many leptospermums, and the original manuca has white flowers, and some manuca honey bushes have different coloured flowers such as 'crimson glory'. Does it matter which variety I get, and can the flowers/leaves still be used medicinally, just like the honey is made from it also.?
