Frankincense

What herb was used for thousands of years, gifted to kings alongside gold, and yet was likely worth even more by the pound? To find it, you would have to travel more than 8,000 miles to Ethiopia or the Somali Arabian Sea. You’d cross harsh deserts where only the hardiest plants survive. Even then, the tree does not give itself freely; It must be bruised.  After that wound, and after nearly two weeks of waiting, the tree releases one of the purest substances it can offer. 

Tears. 

Think about it. When you are cut, what happens? If it hurts badly enough, you cry. Then you clean the wound, disinfect it, and seal it with protection, a bandage, a barrier. Trees respond the same way. Their tears are a defense and once dried they become what we call resins.
