We make traditional incense here, which is made of an aromatic leaf tree. Is it sandalwood?

Sandalwood generally refers to sandalwood. Traditional sandalwood refers to sandalwood produced in India, also known as Laoshan sandalwood, also known as white skin Laoshan incense or Indian incense. Produced in India, the rope is large and straight, the surface is smooth and dense, and the aroma is mellow. It is a good sandalwood.

I don't know if the geranium tree you mentioned is sandalwood, but if it is, it can be sandalwood in a broad sense.
