advice on starter herbs

I’m new to herbalism and just finished reading Herbal Medicine for Beginners. The main issues I want to address are acne and detoxification, ADHD, menstrual cycle irregularities, and anxiety/depression.

I also have a fungal infection in my gut and am following a low-mold diet. Additionally, I have histamine intolerance and am supposed to be following a low-histamine diet.

Here’s what I’ve ordered so far: Wood Betony, Yarrow, Spearmint Leaf, Holy Basil (Rama), Dandelion Root, Pau d’Arco Bark, and Nettle.

My questions: Are these herbs good for my specific concerns? Is there such a thing as too many herbs at once? Is it inconsistent or ineffective to rotate between herbs? (If not, how do people rotate?)
