Chuan Xiong Cha Tiao San

What is Chuan Xiong Cha Tiao San?

Chuan Xiong Cha Tiao San is a Chinese herbal blend for headaches. It is used most for head pain that starts with a chill, a cold or a draught of wind. The blend holds about eight herbs.

You take it as a powder or a pill. You wash it down with green tea. Its full English name is "Ligusticum Chuanxiong Powder to be Taken with Green Tea".

Our library lists this as one entry, a TCM (traditional Chinese medicine) formula. So this page covers the whole blend, not one plant.

Practitioners use it mainly for head pain:

migraine tension headache sinus headache the headache that comes with a common cold

It is meant for short courses. It is not for daily long-term use.

The short evidence verdict: the blend has deep roots in tradition. But there is very little good human trial evidence. Long use is not proof that something works.

It also carries real safety concerns. Some versions hold Xi Xin (Asarum). This herb is linked to kidney damage and cancer.

Please read the safety section before you consider using it.

How does Chuan Xiong Cha Tiao San work?

Honest answer: no one has shown clearly how this blend works in the body. Most of what you will read is theory, not proof.

In Chinese medicine, the blend is said to "release wind from the exterior". It is also said to unblock the channels of the head.

In plain words, practitioners see it as warming and moving. It is aimed at head pain set off by cold air, wind or the start of a cold.

Lab work gives some hints. Chuan Xiong (Ligusticum) holds compounds that relax blood vessels. In test tubes and animals, they also cut platelet stickiness (how easily blood cells clump to form a clot).

Several herbs in the blend show anti-inflammatory effects (they calm swelling) in lab tests. None of this has been shown to explain any benefit in people.

What forms does Chuan Xiong Cha Tiao San come in?

You will usually meet it in one of a few forms:

Loose powder, measured out by a practitioner and stirred into warm green tea. Ready-made tea pills or tablets. This is the most common form in shops.

Strong granules that melt in hot water. Clinics often use these.

Some Western sellers leave out Xi Xin (Asarum) or swap it for another herb. They do this because of the kidney and cancer risk.

Check the full ingredient list on the label. If it is not printed, ask the seller.

Where it comes from:

The formula first appears in the Tai Ping Hui Min He Ji Ju Fang. That was an official Chinese pharmacy book from the Song dynasty, around 1107 CE.

It has been in use ever since. Every modern Chinese medicine course teaches it as a standard headache formula.

The green tea is part of the first written instruction. It is not a modern add-on. Old texts say the tea is cooling and moves down, which balances the warm herbs that move up.

What does Chuan Xiong Cha Tiao San help with?

• Headache that starts with a cold or chill: This is the formula's classic use and the one with the strongest traditional backing. Practitioners choose it when head pain comes on with a chill, a stiff neck, a runny nose or after exposure to cold wind. There is no good human trial evidence testing it for this specific pattern.
• Migraine: Migraine is the most studied use, but the studies are weak. Most are small trials published in Chinese journals, often without proper blinding or a placebo group, so we cannot tell benefit from expectation. We could not identify a large, well-run trial to cite.
• Tension headache: Traditionally used for the dull, band-like head pain that comes with a tight neck and shoulders. Evidence in people is limited to small, low-quality reports. Simple measures such as sleep, hydration and posture have better support.
• Sinus headache and facial pressure: Bai Zhi and Qiang Huo are traditionally said to open the head and face, and the formula is often used for pressure across the brow and cheeks. This use rests on tradition and practitioner experience, not on trial data. Pain with fever, coloured discharge or swelling needs medical assessment.
• Stiff neck and shoulders with head pain: The formula is traditionally paired with head pain that spreads into the neck and upper back. No human trials have tested it for neck stiffness on its own.
• Common cold with head and body aches: Used in the first day or two of a cold, when aching, chills and headache dominate. Traditional standing here is long, but there is no reliable trial evidence that it shortens a cold or reduces symptoms.

What are the side effects of Chuan Xiong Cha Tiao San?

• Nausea or upset stomach
• Loose stools
• Dry mouth
• Dizziness or light-headedness
• Feeling flushed or warm
• Trouble sleeping, mostly from the green tea's caffeine
• Rash or itching from an allergic reaction
• Swollen ankles, rising blood pressure or muscle weakness from the licorice
• Easier bruising or bleeding
• Kidney damage, from any Xi Xin (Asarum) content that carries aristolochic acid

Good to know:

Mild stomach upset and sleeplessness are the common complaints, and they usually settle when you stop.

The serious risks are less common but much more important. Licorice effects build up with weeks of use and show as puffy ankles, higher blood pressure or muscle weakness. Aristolochic acid from Asarum can damage the kidneys silently, and that damage can be permanent, so ingredient checking matters more than dose here.

Options to discuss with a clinician

For every problem this formula is reached for, there are routes with better safety records behind them — and each one is a conversation to have with a doctor, pharmacist or qualified herbalist, not something to pick up on your own.

**For colds with aches and chills:** Andrographis, Black Elderberry, Echinacea, Vitamin C and Garlic have all been studied for cold symptoms and duration, and Honey has reasonable evidence for the cough that often comes with them. A pharmacist can tell you which, if any, suit you and whether they clash with your other medicines.

**For migraine:** Magnesium, Vitamin B2 (Riboflavin), Ubiquinol/Coenzyme Q10 (CoQ10) and Feverfew are the ones with trial evidence worth asking a clinician about. Migraine also has well-tested prescription prevention — worth raising at the same appointment.

**For tension headache and stiff neck and shoulders:** Biofeedback (learning to control muscle tension with feedback from a monitor) and regular Exercise both have good evidence. A physiotherapist or GP can point you to local options.

**For sinus pressure and facial pain:** Saline Nasal Rinse, Steam Inhalation and Eucalyptus Oil are commonly discussed with pharmacists for blocked sinuses.

**For headaches that are new, severe or changing:** get the cause diagnosed first — that comes before any remedy.
