Our family uses pine nut oil enriched with pine resin to treat the stomach (gastritis) and oral cavity. Our stomachs began to ache less — the resin balsam had to be taken for a couple of weeks, but the stomatitis and gum problems generally disappeared immediately! The general state of our health became better, I feel hale and hearty, so the balsam works. When my brother was taking pine resin balsam, his whole family contracted a severe respiratory illness, but he did not get sick, even though he is the one who usually gets sick first and is sick for a long time. So the information about the prevention of colds has also proved to be true.
