To cut down on antibiotic use, I use honey for wounds, it's amazing stuff. Husband's bypass scar has completely disappeared and a lot of the other folk in the "zipper club" group have horrible ugly scars. Because we used medicinal honey ointment. Also on minor skin infections - it's sticky but dab some on gauze and slap it on then sellotape it on
I used to make an excellent cough mix from Thyme - it helped my youngest son's asthma when he was a bairn. He used to get a horrible cough and tightness, and a simple infusion of thyme and honey worked wonders.
Life is harder now we're old and bits of us keep falling off, so now I've moved onto diet. You can experiement with diet a lot. Main prob for me is mobility and I haven't yet found anything that works. Yet.
Loving all your answers, very interesting
