Block Island (RI)is overgrown with Bayberry bushes which do produce 3 mm hard "berries" which yield a wax when boiled in enormous numbers. The resulting wax has a very pleasant odor when burned as a candle. While the LEAF here is used as a seasoning (like real bay leaves) I'm sure that the Berry is NOT for ingestion in any form! I'm sure the tea reference is a different Bayberry.
Bayberry bushes are never allowed to grow here in proximity to buildings because of their intense heat in brush fires. I think that Massachusetts, the BAY STATE was nicknamed after its once-abundant bayberry bushes.
