Use Gastrodia elata during cold fever period

Gastrodia elata mainly calms liver wind, relieves dizziness and unblocks meridians without antiviral, heat-clearing, detoxifying or sweat-inducing effects for colds. Taking Gastrodia elata randomly while suffering cold and fever will delay recovery and aggravate discomfort in most cases.

1. Why ordinary cold fever crowds should avoid Gastrodia elata

Reason 1: Gastrodia elata has no therapeutic effect on colds and wastes physical energy

Colds and fevers arise from external pathogenic invasion (wind-cold, wind-heat). Clinical treatment requires dispersing external pathogens, clearing heat or inducing sweating to expel pathogenic factors out of the body.

Gastrodia elata acts on the liver meridian to suppress liver yang and wind, cannot dispel wind evil from the body surface. It cannot reduce fever, relieve sore throat, nasal congestion or cough at all. Taking it does nothing for cold recovery.

Reason 2: Sedative property suppresses body defense response and prolongs fever duration

Mild fever is the immune system fighting against viruses and bacteria. Gastrodia elata inhibits central nerve excitability, weakens the body’s sympathetic response, slows immune reaction speed, making the body less capable of eliminating pathogens. As a result, colds drag on longer, fever recurs repeatedly.

Reason 3: Vasodilation easily causes dizziness, palpitations & physical collapse

When fever occurs, blood circulation speeds up naturally. Gastrodia elata dilates blood vessels further, which leads to:

• Dizziness, vertigo, lightheadedness when standing;
• Rapid heartbeat, palpitations, fatigue, profuse sweating; Elderly and weak people may experience excessive sweating, electrolyte loss and physical exhaustion.

Reason 4: Mild slippery property worsens gastrointestinal discomfort of cold patients

Many cold sufferers suffer stomach bloating, poor appetite or loose stools. The mild laxative characteristic of Gastrodia elata irritates the intestines, triggering diarrhea, hurting the spleen and stomach, and reducing nutrient intake during illness.

Reason 5: Wind-heat cold + Gastrodia elata easily generates internal stagnant heat

Patients with wind-heat cold (high fever, sore throat, yellow phlegm, dry mouth) taking Gastrodia elata will trap heat pathogens inside the body; fever subsides slowly, and symptoms such as mouth ulcers, dry cough will appear secondarily.

2. Special situations: Limited use of Gastrodia elata is permitted (only for targeted symptoms)

Gastrodia elata can be temporarily used only if the cold triggers severe liver-wind dizziness, under strict dosage control, and must be combined with cold-relieving ingredients:

1. Wind-cold / wind-heat cold accompanied by violent headache, splitting migraine, vertigo caused by fever-induced liver-yang ascent;
2. Fever triggers nerve tension, severe insomnia and cannot fall asleep for days;

Strict usage rules for these scenarios:

1. Daily dosage of dried Gastrodia elata ≤ 0.5 g (ultra-low dose); never take pure Gastrodia elata powder alone;
2. Match cold-treatment ingredients: wind-heat cold pairs with chrysanthemum, mint, mulberry leaf; wind-cold cold pairs with ginger, perilla leaf to dispel external pathogenic factors first;
3. Stop Gastrodia elata immediately once fever drops below 37.3 °C, continue cold treatment only;
4. Continuous use shall not exceed 2 days.

3. Classified prohibition rules for different cold types

1) Wind-heat cold (high fever, sore throat, yellow nasal discharge, red tongue)

Totally forbidden to take Gastrodia elata. It traps heat inside the body, aggravates inflammation and fever.

2) Wind-cold cold (chills, runny clear nose, no fever or low-grade fever, body aches)

Avoid single Gastrodia elata. If accompanied by severe headache, mix tiny Gastrodia elata with ginger and perilla for auxiliary relief only.

3) Viral cold with high fever above 38.5°C

Absolutely stop all health herbs including Gastrodia elata, focus on fever reduction, hydration and antiviral care.

4) Cold accompanied by diarrhea, poor digestion

Ban Gastrodia elata entirely to prevent aggravated loose stools.

4. High-risk crowds who must never consume Gastrodia elata while having a cold

1. Children with cold fever (immature spleen and stomach, prone to diarrhea and listlessness);
2. Elderly people with cold + hypotension (easy to faint from combined vasodilation);
3. Weak people, postpartum women with colds (Gastrodia elata consumes qi and delays recovery);
4. People taking cold medicine, antipyretic drugs together: superposed sedation leads to drowsiness, slow reaction.

5. Correct processing sequence

1. Priority: Treat cold and fever first, use cold medicines, drink warm water, rest, wait until body temperature returns to normal, nasal congestion and cough basically disappear, then resume regular Gastrodia elata conditioning;
2. If you accidentally take Gastrodia elata during fever: suspend consumption, drink warm boiled water or millet soup, monitor body temperature; if dizziness or persistent fever occurs, seek medical treatment;
3. Do not use Gastrodia elata soup as nourishing tonic during cold recovery period within 3 days after fever fades.

6. Conclusion

In most cases of cold and fever, do not take Gastrodia elata. It cannot cure colds, suppresses immunity to lengthen illness duration, and may cause dizziness, diarrhea and recurrent fever.

Only when cold induces severe migraine and vertigo caused by liver wind, ultra-low-dose compound collocation can be used temporarily for 1–2 days. Once fever is gone, discontinue Gastrodia elata right away and resume conditioning after full recovery from the cold.
