Why is this so harsh? -Vape-

This (below) translated to -la la la duh- for me. Is this process why this brand is so harsh IMO. I get a sore throat too sometimes.

Tree Sap Xtrax start with a base of pure, food-grade propylene glycol (PG) and polyethylene glycol, mixed in our proprietary blend. From there, we add Tree SapConcentrate, creating a solution of unmatched potency and clarity.

Extraction Technique

All Tree Sap concentrates are made with our proprietary extraction methods, which utilize supercritical fluid extraction (SCFE) and Microwave Hydrodiffusion and Gravity (MHG) technologies to achieve the highest degree of purity and clarity. Raw materials are processed at multiple stages until our concentrates are completely free of all solvents, contaminants and plant-material, ensuring the cleanest tasting and most potent product possible..

It's the PG that is burning your throat.

"Propylene Glycol (PG) : better throat hit and flavor. PG e-liquid is thinner and produces more of a “throat hit” than VG e-liquid does, which simulates the feel of smoking better. PG e-liquid also has a higher rate of sensitivity for some people,meaning that some people just can't use PG in their vape."

Thank you
