Hydrangea amacha

Hydrangea amacha

"Amacha" group (sweet tea)

This group of plants belongs to a wider group of hydrangeas, called Yama, originating in the mountainous areas of Japan (Yama trad. Mountain) and all classifiable in the serrata species.

The fundamental element that distinguishes Amacha from Yama is the "flavor" of the leaf.

In fact, the Amachas, if chewed, show a strong sweet taste. Excluding DNA tests, this seems to be the only way to consider Amacha and Yama separately. The scientific reason why plants of the same group of belonging develop such a different characteristic is still unknown today.

The infusion obtained from Amacha leaves has had, and still has many uses, both in herbal medicine and as a substitute for sugar, and for religious celebrations. The best known is the "Kambutsu-e" rite, a ceremony that commemorates the birth of Buddha.

The sweet tea of ​​ortnesia, which many plant and herbalists will surely have already had the pleasure of trying, is an extract that is obtained from the leaves of these varieties.

There are about ten varieties of amacha hydrangeas, but the most widespread and cultivated ones are those we will talk about shortly, namely the Yae-No-Amacha, the Amagi - Amacha and finally the Oamacha.
