Q: Which plants on this list should never be used during pregnancy? Leaf of Life, Neem, Comfrey, Nettle, Feverfew, Yarrow, and Pennyroyal all carry documented pregnancy-related cautions (uterotonic activity or toxicity).
Q: Which plant has the strongest clinical backing overall? Turmeric and Aloe Vera currently have the most robust human clinical evidence among traditional medicinal plants.
Q: My tea tastes bitter/off — did I over-prepare it? Over-boiling leaves (common with Leaf of Life, Nettle, Peppermint) can degrade beneficial compounds and increase bitterness. Simmer gently, 5–10 minutes max.
Q: Is "Leaf of Life" the same as "Tree of Life"? No — they're unrelated species. This is one of the most common naming mix-ups in herbal reference lists.
Q: How do I decide between tea vs. topical use? Check the "Common Prep Method" column — plants like Comfrey are topical-only due to internal toxicity risk, while Leaf of Life and Aloe Vera support both routes.
