50 to 70 per cent resinous compound of benzoic and benzoyl-acetic acid, with dracoresinotannol, and also dracon alban and dracoresene. Not acted upon by water, Dragon's Blood fuses through heat.
A primary constituent (about half) of Dragon's Blood is benzoic acid, C7H6O2 (C7H5COOH), a "colorless crystalline solid and the simplest aromatic carboxylic acid."
Considering the chemical molecular formula, we see that there are in total 7 carbon atoms, 6 hydrogen atoms and 2 oxygen atoms in the molecule. Kabbalistically, the numbers are zayin (ז), vav (ו) and a chatoteret comprised of 2 lines. These number facts of 7-6 and 2 (the chatoteret) combined into one molecule make the letter chet (ח), which contains the secret to both the power of G-d and the soul of mashiach.
A diagram of the chemical structure of benzoic acid is shown below. Note the hexagonal shape of the aromatic carboxyl group. A regular hexagon (like the one shown) has 720  degrees made of 6 equal internal angles of 120 degrees each. Interesting to consider in terms of the tetragrammaton and four forces from one, a truncated tetrahedron (split in half) has 4 regular hexagonal faces. The Hebrew word for half and arrow is the same word, חץ.
 There are 720 possible permutations of the 6 letters בראשית Bereshit (the first word of the Written Torah), a secret of challah and the tikun of tohu.
