Acute tonsillitis
Also known as: acute tonsillitis, acute exudative tonsillitis, acute bacterial tonsillitis, streptococcal tonsillitis, viral tonsillitis, acute tonsillopharyngitis
Acute tonsillitis is an acute inflammation or infection of the palatine tonsils, usually occurring as part of an acute sore-throat or tonsillopharyngitis syndrome. Symptoms may include throat pain, painful swallowing, fever, headache, fatigue, enlarged tender cervical lymph nodes and red, swollen tonsils with or without white exudate. Most acute sore-throat illnesses are viral and improve within approximately one week without antibiotics. Group A Streptococcus is an important bacterial cause, particularly in school-aged children, and confirmed or appropriately diagnosed infection may require antibiotic treatment to reduce transmission and prevent complications. Clinical features alone cannot always reliably distinguish viral from streptococcal infection. TCM differentiation commonly includes Wind-Heat invading the Lung, Wind-Cold constraining the exterior, Lung and Stomach Heat, Heat-Toxin congesting the throat, Phlegm-Heat obstruction, or residual Lung and Kidney Yin deficiency. Acupuncture and Chinese herbal medicine are adjunctive and must not delay airway assessment, streptococcal testing, prescribed antibiotics, abscess drainage or urgent management of epiglottitis, peritonsillar abscess, deep-neck infection, diphtheria, anaphylaxis or sepsis.

Lifestyle & Diet
- •Most uncomplicated acute sore throats and tonsillitis episodes improve within approximately one week, with or without antibiotics.
- •Use age-appropriate paracetamol or ibuprofen when suitable and according to medical or pharmacy advice.
- •Maintain fluids with small frequent sips; seek assessment if swallowing fluids becomes difficult or urine output decreases.
- •Warm or cool non-irritating fluids and soft foods may be used according to comfort.
- •Avoid smoking, vaping, alcohol and airborne irritants while the throat is inflamed.
- •Rest the voice and avoid persistent throat clearing or shouting.
- •Wash hands regularly and cover coughs and sneezes.
- •Do not share cups, eating utensils, toothbrushes or mouth-contact items during contagious illness.
- •Complete prescribed antibiotics as directed and do not share or retain leftover antibiotics.
- •Clinical features suggesting group A streptococcal infection include sudden sore throat, fever, tonsillar inflammation or exudate and tender anterior cervical nodes, while cough, rhinorrhoea, hoarseness, oral ulcers and conjunctivitis favour viral illness.
- •Clear viral symptoms may make streptococcal testing unnecessary, but testing may be required when viral features are absent because examination alone cannot reliably distinguish viral from group A streptococcal infection.
- •Follow medical advice about return to school, childcare or work after confirmed group A streptococcal infection.
- •Avoid strenuous exercise and contact sport when infectious mononucleosis or splenic enlargement is suspected.
- •Seek reassessment for worsening pain, dehydration, rash, breathing difficulty, drooling, unilateral swelling, trismus or failure to improve.
- •Recurrent tonsillitis may require primary-care or ENT assessment to review episode frequency, severity, airway symptoms and suitability for further management.
Cautions & Contraindications
- •Do not treat suspected epiglottitis, peritonsillar abscess, deep-neck infection, diphtheria, anaphylaxis or sepsis with acupuncture or herbal medicine alone.[,]
- •Do not aggressively depress or examine the tongue when critical airway narrowing or epiglottitis is suspected.[]
- •Do not give oral herbs, tablets, lozenges, food or fluids to a patient who cannot swallow safely or is at risk of aspiration.[]
- •Do not delay prescribed antibiotics for confirmed or appropriately diagnosed group A streptococcal tonsillitis, scarlet fever or another bacterial infection.[,]
- •Do not advise stopping antibiotics because symptoms have improved.[,]
- •Avoid local anterior-neck acupuncture when airway compromise, abscess, cellulitis, significant swelling or anatomical uncertainty is present.[]
- •Avoid bleeding techniques in anticoagulated patients, bleeding disorders, severe anaemia, thrombocytopenia, immunosuppression or when sterile technique and consent cannot be assured.
- •Avoid strong warming formulas or moxibustion in high fever, marked tonsillar redness, purulent exudate, strong thirst or a red tongue with yellow coating.
- •Avoid strong bitter-cold formulas in a clearly Wind-Cold or markedly deficient presentation, especially during prolonged use.
- •Bàn Xià and Dǎn Nán Xīng must be correctly processed; raw forms are toxic.
- •Xìng Rén requires professional dosing because of cyanogenic toxicity risk.
- •Do not use prohibited, adulterated, contaminated or incorrectly identified herbal substances.
- •Screen herbal prescriptions for age, weight, pregnancy, breastfeeding, allergy, hepatic or renal disease and interactions with antibiotics, analgesics, anticoagulants and other medicines.
- •Do not administer adult herbal doses to infants or children.
- •Do not apply caustic, highly concentrated or unsterile substances directly to the tonsils or pharynx.
- •Do not repeatedly attribute persistent unilateral tonsillar enlargement or neck lymphadenopathy to residual Heat without appropriate medical investigation.[,]
- •Do not assume tonsillar exudate proves bacterial disease or that its absence excludes group A streptococcal infection.[]
- •Do not interpret symptomatic improvement as evidence that complications are absent.
When to reassess or seek care again
- •Expect resolution within 5–7 days; reassess at 3 days if not improving or systemically worsening.[,,]
- •Urgent review for drooling, stridor, trismus, muffled 'hot potato' voice, unilateral peritonsillar swelling, or dehydration — assess for quinsy or airway compromise.[,,]
- •Reassess 2–4 weeks after streptococcal episodes for post-streptococcal complications (scarlet fever, rheumatic fever, glomerulonephritis).[,]
- •Consider ENT referral for recurrent tonsillitis meeting Paradise/SIGN criteria (e.g. ≥7 episodes in 1 year, ≥5/year over 2 years, ≥3/year over 3 years).[,]
- •Close household or school contact with GAS, and shared utensils/drink bottles.[,]
- •Smoking, vaping, dry indoor air, and repeated Wind-Heat invasions.[,]
- •Constitutional Lung/Kidney yin deficiency with chronic low-grade throat symptoms.[]
Frequently Asked Questions
What is acute tonsillitis?+
Acute tonsillitis is an acute inflammation or infection of the tonsils causing sore throat, painful swallowing, fever, swollen cervical lymph nodes and red, swollen tonsils, sometimes with white exudate [3].
Are most cases of acute tonsillitis bacterial?+
No. Many episodes are viral and improve within approximately one week without antibiotics. Group A Streptococcus is an important bacterial cause, particularly in children aged approximately five to fifteen years [3].
Does white pus on the tonsils prove streptococcal infection?+
No. Tonsillar exudate may occur with group A Streptococcus, Epstein-Barr virus and other infections. Clinical assessment and appropriate testing may be required [3].
What symptoms suggest a peritonsillar abscess?+
Severe one-sided throat pain, trismus, a muffled hot-potato voice, uvular deviation and unilateral soft-palate or tonsillar swelling suggest possible peritonsillar abscess and require urgent assessment [3].
When is tonsillitis an emergency?+
Emergency assessment is required for breathing difficulty, stridor, drooling, inability to swallow saliva, rapidly increasing swelling, severe neck stiffness, confusion, collapse or suspected epiglottitis, anaphylaxis, deep-neck infection or sepsis [3].
What are common TCM patterns for acute tonsillitis?+
Common patterns include Wind-Heat invading the Lung, Wind-Cold constraining the exterior, Lung and Stomach Heat, Heat-Toxin congesting the tonsils, Phlegm-Heat and residual Lung-Kidney Yin deficiency [7].
Which acupuncture points are commonly considered?+
Commonly considered points include LU10, LI4, LI11, LU7, SJ5, ST44, KI6, REN22 and LU11. Anterior-neck points and bleeding techniques require advanced safety precautions [7].
Can acupuncture or herbs replace antibiotics for streptococcal tonsillitis?+
No. They may be considered adjunctively but must not replace testing or prescribed antibiotics when group A streptococcal infection requires treatment [7].
When should recurrent tonsillitis be investigated?+
Frequent episodes, airway obstruction, sleep disturbance, recurrent abscess, persistent unilateral enlargement or substantial effects on school, work or wellbeing warrant medical or ENT review [3].
