Natural health: I feel tired and find it difficult to concentrate after Covid 

Another reader asks for advice on recurring UTIs

Rehmannia root, star anise, schisandra berries, nigella seeds, fennel seeds, and turmeric root are all helpful

I picked up Covid for the second time three weeks ago. I got over the symptoms quickly but still feel tired and find it difficult to concentrate at work. Is there a herbal remedy I could take?

One of the most effective herbal combinations I make for patients suffering from post-viral fatigue includes Rehmannia root, star anise, schisandra berries, nigella seeds, fennel seeds, and turmeric root.
