I’d love to have a good substitute for cilantro and cumin in recipes that will support detox and gut repair. Any thoughts?

Basil, dill, and parsley support detox wonderfully. Coriander is a good replacement for cumin (although that's Indian cilantro). You can never go wrong with turmeric, and when you add freshly ground black pepper to it, you TRIPLE the absorption of curcumin (its anti-inflammatory compound).
