For thousands of years, #Tree #Resins known as #Frankincense (white/milky) & #Myrrh (reddish) were used to make #Sweet #Perfume, Incense, & #Medicine.

The #Trees are #Native to #Arabia & NE #Africa.

To #Collect the resins, the #Bark is cut, which allows the #Essence to seep out & dry into #Crystals.

#Nomads sold the #Prized #Aromatics, which were as #Precious as #Gold, #Gems, or #Spices.

Frankincense is #French for #Pure #Incense.
Myrrh is #Semetic for #Bitter.
