How Much Dandelion Should You Take? A Sensible Range

Dose is where herbal advice usually falls apart. Dandelion is safe at food levels and questionable above them, and this page draws that line with actual numbers where the research gives them.

The working range

9 to 30 grams dried leaf or root in decoction; young leaves also go into salads and soups.

Stay at food level: a few cups of tea, a spoon of powder, the amounts a cook would use. Concentrated extracts compress several servings into one capsule, so follow the label rather than free-pouring.

What the studies used

Less is known about the safety of taking dandelion in larger amounts. Some evidence suggests that topical dandelion may cause an allergic reaction in people who have atopic dermatitis (eczema).

Signs you have overdone it

Dandelion is cold in nature. Push a warming herb hard and you feel flushed, restless, dry-mouthed; push a cooling herb and digestion turns sluggish. Either way, the fix is the same: stop, let things settle, restart at half the amount.

When public health concerns arise about the safety of a dietary supplement or an ingredient including an herb, the FDA can take action to protect the public. Manufacturers and distributors of supplements are responsible for evaluating the safety and labeling of their products before marketing to ensure that they meet all regulatory requirements.

Consistency beats dose. A modest amount taken regularly usually does more than a heroic amount taken twice.
