Biosynthesis not biosyntheticOkay. I made a mistake. Willow's process is biosynthesis. Taking the plants DNA instructions and letting it go to work in a specialized yeast to make exactly the same thing the DNA makes in the plant. ( only the amount in the plant is very small) Biosynthetic is different. I believe this is where through chemical formulas, a lab attempts to make a synthetic replica of what is in nature. Willow doesn't do this. They harness the power of the DNA instructions to make exactly what the plant makes
