Fatigue and low energy

The seventeen species under this topic form two layers that popular texts often merge. The first is the European spring cure — stinging nettle, dandelion, field horsetail, with common hawthorn, small-leaved lime and fruits such as raspberry, lingonberry or bilberry. The frame is seasonal: after winter, briefly, as part of a meal.

The second layer is the 20th-century category 'adaptogen', which covers ashwagandha, jiaogulan or cancer bush. It is neither a botanical group nor a pharmacological class but a loose label from popular literature — the catalogue takes it as a description of traditional use, not as a claim about an effect on fatigue.

Fatigue is a symptom with a long list of causes: iron or B12 deficiency, a thyroid disorder, sleep apnoea, depressive disorder, a side effect of medication, lack of sleep. A herbal infusion acts on none of them.

The documented approach is therefore diagnostic, not herbal — find the cause and replace only what has actually been measured. Supplements 'for energy' taken blind have no documented effect, and with iron in excess they do harm.

Fatigue lasting more than a month, or fatigue that changes how the ordinary day works, belongs with your GP and a blood test, not with a choice of tea.

Have fatigue with weight loss, night sweats, breathlessness on ordinary exertion, pallor or bleeding assessed without delay. A chapter of its own is exhaustion after an infection that worsens after exertion — there, pacing the load is part of the care.
