Origin:

Shenhua was first born in India, and was introduced to Europe during the colonial period. It was called Roselle and was widely cultivated. Because Europeans find it is a good food raw material, and it can also be used to make sauces and essential oils.

Later, Luoshenhua was introduced to Taiwan Province Province, China, and China people literally translated its English name Roselle as "Luoshenhua", so it was named "Luoshenhua", which has nothing to do with Luoshenhua.
