Burdock, the all-purpose alterative
In Sajah Popham's spring tonics lesson, burdock root is “the all-purpose alterative”: a mild, almost neutral herb that cleanses the blood through the liver, lymph, kidneys and skin while its inulin feeds the gut. The inulin is real — half or more of the dried root — and inulin does feed good gut bacteria in people, though a prebiotic dose means about 88–125 g of fresh root. For the skin the EU accepts burdock as a traditional remedy, without robust trials; for the liver and lymph we found no studies. It was an ingredient of the Hoxsey cancer tonic, which is no cure, as the lesson itself says.
50–70% of dried burdock root is inulin, by the review figures — 12–17% of the fresh root

Dandelion leaf, the potassium diuretic
In Sajah Popham's spring tonics lesson, dandelion leaf is “the universal diuretic”: bitter, cooling, drying, and “potassium-sparing” because it brings in the potassium that a water tablet washes out. The one study in people, 17 volunteers over a single day with no placebo group, found a real but small diuretic effect. The leaf is rich in potassium — but that is a reason for care, not a swap for medicine: the EU warns against it with kidney failure, diabetes or heart failure. Its use for blood pressure rests on rats; for gout, bile, anaemia and bones, on tradition.

Nettle, the mineral powerhouse
In Sajah Popham's spring tonics lesson, nettle leaf is the “mineral powerhouse”: a food to cook, a gentle diuretic, a tonic for the blood and a remedy for hay fever. The calcium is real — a cup of cooked nettles gives a third of a day's needs — but the iron is not: nettles have about half the iron of dandelion greens, which the same lesson calls “not super rich in iron”. One small trial supports nettle for hay fever; the urinary, joint and skin uses are traditional, recognised by the EU; anaemia, gout and bones are untested.
33% of a day's calcium in one cup of cooked nettles — 428 mg
