My husband has had allergies, chemical sensitivities (neighbor's clothes dryer and hot tub chemical smells) and sinus congestion for the last 14 years. It would hurt me to see him come back from a walk, all stuffed up with a sinus headache that would linger for days. He would netty pot and press his head and wait for it to let up. Then, he fell and bruised a rib and was in pain from lung congestion, so after addressing the rib injury, I suggested he take a fenugreek/thyme tincture I had made for him. It was amazing. Within two days his congestion was cleared and then he found over the next few weeks that he was not reacting to the usual smells and his sinuses were clear. He missed a day and it came back, but was stopped when he resumed taking the tincture. My understanding is that a person's constitution...his is wet and cold/mine is hot and dry...is important when taking herbs. Both fenugreek and thyme are warming and drying so they wouldn't do me that much good, but for him they connected the right dots. He even finds he doesn't get chilled as easily and his nose isn't running all the time. Everyone is different, but this was such a game changer for him (and me too) that I wanted to pass it along.
