What is the quality of traditional pressed tea oil?

Squeezing is simply squeezing oil out by pressure. No adjuvant was added. However, in the squeezing method, some oil is not squeezed out and remains in the tea cake.

Therefore, people invented the leaching method, using an organic solvent to "cover" tea oil from tea cakes, and then separating the organic solvent from tea oil. A small amount of organic solvent will run into camellia oil. If this organic solvent exceeds the standard, it will be harmful to human health.
