Body cleansing (folk framing)

The spring cure is an old thing: after a winter on potatoes and cabbage, people ate the first greens — stinging nettle, dandelion, young leaves — and drank herbs that 'drive water'. The word detox is new and came from marketing; the tradition spoke of 'clearing out' and meant the bowels, urine and sweat.

The catalogue lists seven native species: stinging nettle, dandelion, milk thistle, fennel, elder, red clover and lemon balm. Milk thistle is the bitter 'liver' herb of the European herbals, nettle and dandelion the spring greens, elder the sweating tea — together a picture of a spring habit, not a programme.

The body does not store 'toxins' that could be drunk away; the liver and kidneys process them continuously and herbal tea does not speed up that work. The documented effect of a spring cure is different and real: more vegetables, more water, less alcohol and sugar for a few weeks — the diet changes, not the organ.

Milk thistle has clinical trials in liver disease with standardised silymarin; in a healthy liver there is nothing to 'cleanse'. Dandelion and nettle increase urine output, which people feel as lightening; it is not cleansing, it is water.

The commonest harm of a 'detox' is not the herb but what gets stopped because of it: medication for blood pressure, the thyroid, diabetes or mental health. No cure is a reason to interrupt treatment — only the doctor who prescribed it decides that.

Yellow whites of the eyes, dark urine and pale stool, pain under the right ribs or unexplained weight loss belong with a doctor, not with tea. Long fasts and 'cleansing' enemas have no evidence, and in people with heart disease or diabetes, in pregnancy and in adolescents they are outright dangerous.
