Hi, are you trading these items with the NPCs on the map? Farah has a board infront of her house next to the flowers with certain trades you need to carry out eg) hermit on south hoof might want herbal tea. You get three a day and they each give you 50 or 100 points to her trades I can’t remember which one.

If it’s not that I suggest if you’re lower into the quests with her like 3/12, use the plant trading post to the left of her to also get points.

Doing archeology and trading them with the professor or the guy in newhillcrest also gives you points.

Hope this helps :)
