It is good the ELEMENSE NUKUBAI JAPANESE INCENSE (based on the element earth, do) for a Sagittarius person who is an earth dragon in the Chinese zodiac?
That incense is good, but since it is a blend of different scents it is more for perfuming.
If you want incense more directly related to Sagittarius, pick something that features Lignum Aloes (Aloeswood).
