Mongolian milkvetch is the dried root sold in Chinese herb shops as huang qi. It looks like a pale wooden tongue depressor, tastes faintly sweet, and goes into soups, broths and long infusions. This page covers which part is used, how it is prepared at home, what tradition credits it with, and who should leave it alone.

A short story of huang qi

• Milkvetch root has been used in Traditional Chinese Medicine for more than two thousand years, where it is classed among the tonic herbs rather than the cooling ones.
• A nineteenth-century American school of medicine picked it up and spread its reputation as a root that strengthens the constitution.
• In the late twentieth century, Chinese researchers took an interest in milkvetch preparations after an epidemic affecting the heart muscle; the root has been the subject of laboratory and clinical work ever since, which is one reason a properly trained practitioner is the right person to consult about it.
• In Chinese practice it rarely travels alone: it is blended with other roots into classic formulas, the best known being Yu Ping Feng San.

What it is credited with

• Traditional Chinese Medicine classes milkvetch root as a tonic for depleted energy, given during periods of tiredness and while regaining strength after illness or an operation.
• Herbalists reach for it as a seasonal support through the cold months, particularly for people who catch every sniffle that goes round.
• In Chinese herbal medicine, the formula Yu Ping Feng San, built around milkvetch root, has a long-standing reputation for people prone to repeated colds, winter chest complaints and hay-fever-type rhinitis.
• Naturopathy credits the root with a steadying effect on appetite when eating has fallen off during convalescence.
• Tradition also gives it a place as a restorative for older people and for mothers in the flat, drained weeks after childbirth.
• Its flavonoid content, astragalin in particular, gives it a reputation as an antioxidant plant in the herbalist’s repertoire.
• Chinese tradition has long associated the root with supporting the liver’s resilience, and it appears in formulas given to people carrying a heavy load.

None of this is a treatment. Milkvetch is a tonic root in a tradition, taken in courses alongside sleep, food and rest.

How to use it

Milkvetch root is tough and woody. It needs heat and time: a five-minute steep gets you nothing.

The long decoction

• Put a few slices of dried root, or a small handful of chopped root, into a pan with about half a litre of cold water.
• Bring to the boil, then drop to a bare simmer for a good quarter of an hour, longer if the slices are thick.
• Strain and drink warm across the day. The liquid is straw-coloured and mildly sweet.
• Herbalists generally use it in courses of two to three weeks, with a break, rather than continuously.

In the kitchen, the easiest route

• Drop two or three slices of dried root into a pot of chicken, vegetable or barley broth and let it simmer with everything else.
• Fish the slices out before serving, as you would a bay leaf; they stay woody and are not eaten.
• It pairs well with ginger, jujube dates, shiitake and garlic — the classic autumn and winter soup pot in Chinese homes.

Tincture, powder and capsules

• Tincture: drops in a little water, spread across the day, morning, midday and evening. Follow the dropper guidance on the bottle you have bought.
• Powder: stirred into broth, porridge or a smoothie; split across two or three servings a day rather than taken in one hit.
• Capsules: convenient and tasteless, but concentrations vary hugely between products, so the label is your reference.

Milkvetch butter

• Warm a cup of tahini with a few spoonfuls of pumpkin seed paste in a bain-marie.
• Stir in a few spoonfuls of powdered milkvetch root and a little sesame oil.
• Mix to a smooth paste, loosening with a touch more sesame oil if it feels stiff.
• It stands in for walnut butter on toast, and keeps about a fortnight in the fridge. All the ingredients turn up in organic grocers.

Frequently Asked Questions

The one thing to remember: drop two or three slices of dried root into your winter soup pot and let it simmer — that is the simplest, gentlest way tradition uses huang qi.

Which part of milkvetch do I actually use?

Only the root, dried, and only from plants aged roughly four to seven years. It is lifted in mid-spring and dried before use. Leaves, flowers and seeds are not the herbalist’s material here.

Why does my milkvetch tea taste of nothing?

Because the root is woody and needs a real decoction, not a quick steep. Simmer the slices in water for about a quarter of an hour, then strain. You should get a straw-coloured liquid with a mild, slightly sweet, beany flavour.

Can I take it every day all winter?

Herbalists generally work in courses of two to three weeks with a break between them, rather than continuously. Large quantities over long periods may have the opposite of the intended effect on immunity. A slice or two in the soup pot is a gentler habit than daily concentrated doses.

Who should avoid milkvetch?

Anyone in the middle of an acute infection with fever, pregnant women, breastfeeding mothers and children. If you have an auto-immune condition, have had a transplant, or take any regular medication, speak to your doctor before touching a plant with a reputation for stimulating the immune system.

Is milkvetch butter a real thing?

Yes, and it stands in nicely for walnut butter. Warm tahini with pumpkin seed paste in a bain-marie, stir in powdered milkvetch root and a little sesame oil, and mix to a smooth paste. It keeps about a fortnight in the fridge.
