Olive leaf vs guava leaf
Two astringent tree leaves drunk in the regions that grow the fruit, both taken with honey to make the bitterness manageable, and both by-products of an orchard rather than crops in their own right.

What is being compared
Why these get confused
Neither leaf tastes of the fruit its tree carries, which is what people expect of both. Olive leaf tastes of the tree rather than the oil, and guava leaf has no guava character at all.
Point by point
| Aspect | Olive leaf | Guava leaf |
|---|---|---|
| Where it is drunk | Turkey, Greece, Tunisia and southern Italy, mostly in the olive-growing districts themselves. | Mexico, the Philippines, Indonesia and Nigeria, wherever the tree grows in a yard. |
| Form used | Dried, from winter and spring prunings, washed and dried whole or shredded. | Fresh, almost everywhere it is drunk. Dried imported material is much flatter. |
| Flavour | Firmly bitter and green in a way that belongs recognisably to the olive tree. | Astringent and green with a faint aromatic lift from the myrtle family. |
| Preparation | Boiling water and a long steep, or a simmer, and honey and lemon are standard. | Usually boiled, with a handful of fresh leaves. |
| The practical concern | Spray residues from commercial groves; organic certification is the only real check. | Availability. Fresh leaf does not travel and dried is a different product. |
The short answer
Both are honest by-product drinks with real local traditions. Neither is worth importing dried if the tradition uses it fresh, which is the case for guava.
