1. Herbs are not "rare" - just quality varies. Red plants can give up to 100 Quality which means your flux has higher quality which means your steel has higher quality and so on
2. Good spots for high quality herbs are swamps with forest close to it.
3. steel sickle increases your collecting speed significantly.
4. There are 66 herbs. Every herb has 3 Properties. The first 2 properties are "positive" like toughness, intelligence, stamina atc. The 3rd property is "negative" like poison etc.
-> Only the first 2 Properties can have "flux" "naphta",... property
-> There are 11 Herbs which can have "flux" "naphta",... property
5. Properties are random for every character. Which herbs you can use for flux you can only find out by randomly mixing them up and then make a good order how manage your herbs.
A good propose is managing them in a matrix: This means you can save a lot of writing work:
One example is shown here:

If you want to prepare potions with 3 properties you can see which herb you will need by looking where the prpoerties cross each other in this matrix.
Good luck at searching for herbs
