What it is
Sore throat / pharyngitis involves pain and inflammation in the throat, most commonly from viral infection.
Pain, scratchiness, or discomfort in the throat, most frequently caused by viral infection, though bacterial pharyngitis and other causes require differentiation.

A sore throat (pharyngitis) describes pain, discomfort, raw sensation, or difficulty swallowing localised to the throat and pharynx. It is one of the most frequent reasons for both primary care and self-managed illness. The vast majority (approximately 80–90%) are caused by viral upper respiratory infections including rhinovirus, adenovirus, coronavirus, and Epstein-Barr virus (EBV — responsible for infectious mononucleosis, which produces a severe exudative pharyngitis). Bacterial pharyngitis — most importantly Group A beta-haemolytic Streptococcus (Streptococcus pyogenes, "strep throat") — accounts for approximately 10–30% of cases in children and fewer in adults, and requires antibiotic treatment to reduce risk of rheumatic fever. Non-infectious causes include: gastroesophageal reflux (acid reflux causing pharyngeal irritation), mouth breathing and dryness, environmental irritants, post-nasal drip, vocal overuse, and rarely thyroid pathology or malignancy. Features suggesting bacterial rather than viral aetiology include exudate on tonsils, tonsillar swelling, tender anterior cervical lymphadenopathy, and absence of cough (Centor criteria).
The Evidence
What the research says about sore throat causes, self-care, and when professional assessment matters.
Most sore throats are viral — but cause matters for care
The majority of sore throats are caused by viruses and resolve without antibiotics. Identifying those caused by bacterial infection is important, as it changes management and reduces complication risk.
Difficulty swallowing saliva, drooling, or neck stiffness may indicate epiglottitis — a medical emergency. One-sided throat swelling with a shifted uvula suggests peritonsillar abscess requiring urgent review. In children, sore throat with fever and rash may indicate scarlet fever. A persistent one-sided sore throat in an adult without infection signs warrants professional assessment.
Paracetamol and ibuprofen have strong evidence for pain relief. Warm salt water gargling has good evidence for symptomatic comfort. Honey has moderate evidence for soothing throat symptoms. Herbal options including Pelargonium sidoides, Echinacea, and elderberry have moderate evidence for reducing duration and severity of viral upper respiratory illness.
Antibiotics have no benefit for viral sore throat and carry risks including microbiome disruption and contribution to antibiotic resistance. Group A Streptococcal infection — more common in children — does require antibiotic management to reduce the risk of rheumatic fever. Clinical scoring tools and throat swabs help distinguish bacterial from viral cause.
Traditional Chinese Medicine uses formulas such as Yin Qiao San for acute Wind-Heat presentations. Ayurveda uses warm turmeric gargles and herbal preparations including licorice. Western herbal medicine uses thyme, sage, and marshmallow root for soothing and antimicrobial effects. Evidence for these approaches is generally limited to moderate; they are not a substitute for professional assessment when red flag symptoms or signs of bacterial infection are present.
Aspirin must not be given to children with viral illness due to the risk of Reye syndrome — use paracetamol or ibuprofen instead. Prolonged antibiotic use without confirmed bacterial infection risks microbiome disruption and resistance. Herbal preparations can interact with medications; disclose all supplements to your healthcare provider.
Viral sore throat typically resolves within 7–10 days with supportive self-care. A GP or primary care provider can assess for bacterial infection, perform a throat swab, and advise on appropriate management. Complementary practitioners may support recovery and general resilience, but this is not a substitute for professional assessment when red flag symptoms are present.
