By Tradition
Suram (fever) is a major disease category in Siddha medicine. Theraiyar classifies 64 types of Suram. Muraisuram (intermittent fever) corresponds to malarial fevers — characterized by periodic chills and fever in predictable cycles. Siddha diagnosis emphasizes Naadi (pulse) examination to distinguish fever types.

Theraiyar Sekarappa; Agathiyar Sura Nool 300
Theraiyar classifies 64 types of Suram (fever) with detailed Naadi (pulse) diagnostic criteria for each. Nilavembu is described as the chief herb for Pitha Suram (heat-predominant fever) and Muraisuram (intermittent fever). The nine-herb Kudineer formulation addresses all three Kutram simultaneously — Nilavembu for Pitham, Chukku-Milagu-Thippili for Vatham, and Vettiver-Santhanam for cooling.
Nilavembu Kudineer for acute undifferentiated febrile illness: randomized controlled trial in South Indian primary care
Nilavembu Kudineer group showed significantly faster defervescence (median 2.0 days vs 3.5 days, p<0.001) and reduced duration of body ache and malaise. Platelet counts recovered faster in the Nilavembu group. No significant adverse events. However, no difference in malaria-specific outcomes in the subgroup with confirmed Plasmodium infection (n=38).
Fever was a commonly treated condition in the Egyptian medical papyri, often attributed to the influence of Sekhmet (goddess of plague and pestilence). The cyclical fevers of malaria were endemic in the Nile Delta and well-documented in mummy pathology.

Ebers Papyrus — Remedies for Burning Heat and Fever
Willow (tjeret) prescribed as a cooling remedy for 'burning heat' of the body. Prepared as bark decoction in beer and administered to reduce fever. Also mentioned in fumigation remedies where willow was burned alongside other aromatic substances to purify the sick room.
Salicylates as antipyretic agents: historical use and modern pharmacology
Salicin from willow bark is hydrolyzed to saligenin in the gut, then oxidized to salicylic acid in the liver — providing antipyretic activity through COX-2 inhibition and prostaglandin E2 suppression in the hypothalamus. Lower GI side-effect profile than synthetic aspirin due to slower absorption and lack of direct COX-1 acetylation.
Hakjil (瘧疾) is the Korean term for malaria and intermittent fevers. The Donguibogam dedicates a full chapter to Hakjil, recognizing its periodic alternating chills and fever as a hallmark pattern. Korean practice adapted Chinese anti-malarial formulas with Sasang constitutional modifications — the same fever is treated differently depending on whether the patient is a hot So-Yang type or a cold So-Eum type.

개똥쑥 (Gae-ttong-ssuk) — Artemisia annua / Sweet Wormwood
Artemisia species hold special significance in Korean medicine and culture — mugwort (쑥 Ssuk) is one of Korea's founding mythological herbs. Gae-ttong-ssuk (Artemisia annua) is the Korean name for sweet wormwood, used for intermittent fevers (Hakjil) and heat-toxin conditions.

Donguibogam (동의보감), Heo Jun — Chapter on Hakjil (瘧疾 Malaria/Intermittent Fever)
Heo Jun documented Hakjil as a distinct disease category with periodic alternating chills and fever. Treatment stratified by pattern: for heat-dominant Hakjil, Artemisia-containing and Bupleurum-based formulas prescribed to clear heat from the Shaoyang layer. The text specifically notes fresh-juice extraction of Artemisia as superior to decoction for acute febrile episodes — a method that preserves the volatile heat-clearing constituents.
Artemisia annua in East Asian traditional medicine for febrile illness: systematic review of historical usage and modern pharmacological validation
Systematic comparison of Artemisia annua usage across Chinese, Korean, and Japanese traditions confirmed consistent application for intermittent fevers. Korean texts (Donguibogam, Hyangyak-jipseongbang) uniquely emphasized constitutional modification of Artemisia formulas. Modern pharmacological studies validate artemisinin's antimalarial mechanism (endoperoxide bridge generating free radicals in parasite food vacuole).
Fever diseases were extensively recognized in the tropical lowlands of Mesoamerica. Totonqui (from Nahuatl 'heat') encompassed various febrile illnesses including cyclical fevers consistent with malaria. The Maya of the Petén lowlands had sophisticated knowledge of fever-reducing plants and rituals.
Treatments (1)
Quina / Corteza de Fiebre — Cinchona officinalis
Cinchona bark (quina) was adopted into Mesoamerican practice through inter-regional trade and post-contact transmission from South American indigenous knowledge. The bark's powerful fever-reducing properties made it the primary treatment for cyclical fevers (malaria) in the tropical lowlands. Classified as amargo (bitter) and frío (cold) — ideal for counteracting the excess heat of fever.

Ritual of the Bacabs — Maya medical text: incantations and treatments for fever diseases
The Ritual of the Bacabs contains multiple incantations and herbal treatments for cyclical fevers, distinguishing between fevers by their rhythm and severity. Plant remedies are combined with ritual recitations addressing the spiritual forces governing the fever cycle. The text reflects deep empirical observation of malaria-like fever patterns in the Maya lowlands.
Cinchona alkaloids for malaria: historical pharmacology and clinical evidence review
Quinine from Cinchona bark remains the foundational antimalarial compound. In traditional bark preparations, quinine content varies 2-13% depending on species and preparation. Bark decoctions effective for uncomplicated Plasmodium falciparum and P. vivax malaria. Modern resistance patterns limit efficacy in some regions, but bark preparations contain multiple alkaloids (quinidine, cinchonine, cinchonidine) that may act synergistically.
Fever and heat illness treated with cooling bush medicine preparations and smoking ceremonies. Eucalyptus leaf infusions and steam inhalation are the primary treatments — the volatile oils promote sweating and reduce body temperature. Across many Aboriginal language groups, fever is understood as excess heat that must be drawn out or cooled.

Eucalyptus — Eucalyptus globulus / E. species (Bush medicine)
Eucalyptus is the most widely used Aboriginal medicinal plant. Leaves are crushed for steam inhalation (respiratory), used in smoking ceremonies (spiritual/physical cleansing), and applied as poultice for pain. Aboriginal people discovered the medicinal properties of eucalyptus over tens of thousands of years.

Eucalyptus species in Aboriginal fever management: ethnobotanical survey across northern and central Australia
Eucalyptus leaf preparations documented as primary fever treatment across all surveyed language groups. Methods include steam inhalation over crushed leaves in hot water, drinking warm leaf infusion, and bathing in eucalyptus-infused water. Elders described the treatment as 'pulling the heat out' and 'making the body sweat the sickness away.' Several Elders noted that specific Eucalyptus species are preferred over others for fever, demonstrating sophisticated botanical discrimination.
1,8-Cineole (eucalyptol) antipyretic and anti-inflammatory effects: randomized controlled trial in acute upper respiratory infection
Eucalyptol group showed faster fever resolution (mean 1.8 days vs 2.6 days, p<0.01) and reduced need for antipyretic medication compared to placebo. Anti-inflammatory markers (CRP, IL-6) also improved faster in the eucalyptol group. Steam inhalation component not separately tested.
Fever understood across many tribes as a sign the body is fighting illness, sometimes caused by fever spirits. The primary treatment approach combined the sweat lodge (Inipi in Lakota, Madoodiswan in Ojibwe) to 'sweat out' the fever with herbal preparations — especially Echinacea on the Plains, yarrow (Achillea millefolium) among the Ojibwe, and boneset (Eupatorium perfoliatum) among the Cherokee and Iroquois. The sweat lodge was not merely physical — the ceremony's spiritual dimension was considered essential for driving out fever spirits.

Icahpe Hu (Lakota) / Echinacea — Echinacea purpurea
Echinacea is the most widely used Native American medicinal plant in the modern world. Plains tribes (Lakota, Cheyenne, Kiowa, Comanche) used it for more conditions than almost any other plant — respiratory infections, pain, wounds, snakebite, and as a general immune stimulant.

Echinacea as fever remedy across Plains Indian nations: ethnobotanical synthesis
Echinacea (E. purpurea, E. angustifolia, E. pallida) was the most widely used fever remedy among Plains tribes. Preparation methods were remarkably consistent: fresh or dried root chewed directly, or root decoction drunk as hot tea to promote sweating. The Lakota name 'Icahpe Hu' translates roughly to 'wind medicine' — used to break fevers and fight infections. Comanche warriors carried dried echinacea root as battlefield medicine for both wounds and fever.
Echinacea purpurea for febrile upper respiratory illness: effects on fever duration and immune biomarkers
Echinacea purpurea extract reduced mean fever duration by 0.8 days (p=0.02) and time to defervescence by 16 hours compared to placebo. NK cell activity was significantly increased in the echinacea group at day 3. However, peak fever temperature was not significantly different between groups (p=0.31), suggesting echinacea supports fever resolution rather than suppressing the febrile response.

This cold-extraction method was critical — Tu Youyou's 2015 Nobel Prize-winning insight came from recognizing that Ge Hong's low-temperature extraction preserved the heat-labile artemisinin. Wu Jutong later systematized the formula with Bie Jia for Yin-level lurking heat.
Artemisinin-based combination therapy (ACT) for Plasmodium falciparum malaria: WHO multicenter efficacy trial
Artemisinin-based combination therapies achieved >95% parasite clearance at 72 hours across most sites. Emerging resistance in Greater Mekong Subregion (delayed parasite clearance in 10-30% of patients) prompted WHO to recommend triple-drug ACTs. The traditional whole-herb preparation has not been tested at this scale.
Jwara (fever) is considered the king of all diseases in Ayurveda. Charaka Samhita devotes an entire chapter to Jwara Chikitsa. Vishamajwara refers to irregular or intermittent fevers — the Ayurvedic correlate of malarial fevers — characterized by periodicity and rigors.

Salicin and salicylate-containing plants as antipyretics: from ancient empiricism to modern pharmacology
Willow bark extract demonstrated antipyretic activity in clinical settings, though effect size was smaller than synthetic aspirin at equivalent salicin doses. Multi-compound synergy (salicin + flavonoids + polyphenols) likely contributes to the clinical effect beyond salicin content alone. Historical use for malarial fevers was partially effective for symptom management though not curative.

Noni confirmed as the most widely used febrifuge across tropical Polynesia (6 of 8 island groups — absent only in Aotearoa/New Zealand where the plant does not grow and Marquesas where other plants are preferred). Two primary methods documented: (1) fresh leaf poultice to forehead and body for external cooling, (2) diluted juice taken orally. Fever classification systems documented in Samoan and Tongan traditions distinguish between 'hot fever' (fiva vevela — treat with cooling noni) and 'cold fever' (fiva ma'alili — treat with warming ginger).
Morinda citrifolia leaf extract antipyretic activity: preclinical evaluation and pilot clinical observation in febrile patients
Preclinical: noni leaf extract (200mg/kg) reduced fever by 1.8°C in yeast-induced pyrexia model, comparable to paracetamol control (2.1°C reduction). Pilot clinical: noni leaf tea (3 cups/day) in febrile patients showed mean temperature reduction of 0.8°C at 24 hours, but without a placebo control group, this may reflect natural fever resolution. Scopoletin identified as likely antipyretic constituent via prostaglandin synthesis inhibition.

Glycyrrhiza-containing Korean herbal formula as adjuvant to standard antimalarial therapy: randomized controlled pilot study
The herbal adjuvant (containing Glycyrrhiza as harmonizer) did not significantly improve parasite clearance time (primary endpoint, p=0.31) but significantly reduced fever duration (-18 hours, p=0.02) and improved subjective symptom scores. Post-febrile fatigue recovery was faster in the herbal group.
Eremophila (Emu Bush) as bush medicine: ethnobotanical documentation from the Western Desert and Central Australian language groups
At least 14 Eremophila species documented as bush medicine across the survey region. E. longifolia (Emu Bush) and E. alternifolia most frequently cited for fever and cold treatment. Leaf infusion drunk warm or leaves steamed for inhalation. Several Elders described Eremophila as the primary internal medicine plant of the desert regions where Eucalyptus may be less abundant. Diuretic uses also recorded for E. longifolia.
Antimicrobial and anti-inflammatory activity of Eremophila species: phytochemical screening and biological assay
17 of 22 Eremophila species showed significant antimicrobial activity (MIC < 500 μg/mL against at least one pathogen). E. longifolia, E. sturtii, and E. alternifolia showed the strongest combined antimicrobial and anti-inflammatory profiles. Key bioactive compounds: serrulatane diterpenes, verbascoside, and flavonoids. Anti-inflammatory activity via COX-2 and TNF-alpha inhibition confirmed for E. longifolia.
Traditional Artemisia annua whole-plant preparations vs purified artemisinin: comparative pharmacokinetic study
Whole-plant Artemisia tea showed 40-fold lower artemisinin blood levels compared to standard ACT dosing. However, synergistic compounds (flavonoids, other sesquiterpenes) in the whole plant enhanced artemisinin bioavailability by 2.3-fold compared to purified artemisinin alone. Parasite clearance cannot be predicted from artemisinin levels alone due to multi-compound synergy.

Adoption of Artemisia annua into East African traditional pharmacopeias: ethnobotanical survey of Tanzanian herbalists
Artemisia annua cultivation and use has spread rapidly through East African herbalist networks since the 2000s. 72% of interviewed healers now include it in their antimalarial repertoire, typically combined with neem. Local preparation methods (leaf infusion, not boiled decoction) independently align with optimal artemisinin extraction. Concern: some healers use it for malaria prevention, raising resistance issues.
Artemisia annua dried leaf tablets versus artesunate-amodiaquine for uncomplicated malaria: randomized non-inferiority trial in the Democratic Republic of Congo
Artemisia annua dried leaf tablets showed 89% parasitological cure rate at day 28 versus 95% for ACT (difference not meeting non-inferiority margin). Fever clearance was comparable. Recrudescence was higher in the Artemisia group at day 42 (18% vs 7%). The whole-plant preparation provided multiple bioactive compounds beyond artemisinin.
Diaphoretic use of Zingiber officinale in Polynesian fever management: the 'warming-to-cool' strategy
Ginger tea documented as a fever treatment in Hawaiian (La'au Lapa'au) and Samoan (Taulasea) traditions using a paradoxical 'warming-to-cool' approach: hot ginger tea induces sweating (diaphoresis), which breaks the fever. This strategy is specifically used for 'cold fevers' (fiva ma'alili in Samoan) — fevers with chills and shivering. Hot fevers (fiva vevela) are treated with cooling noni instead. The distinction reflects sophisticated empirical observation of fever patterns.
Ginger (Zingiber officinale) as adjunct antipyretic in acute febrile illness: a randomized controlled trial
Adding ginger tea to standard paracetamol did not significantly improve fever resolution time (mean 18.2 hours vs 19.8 hours, p=0.32). However, the ginger group reported significantly less associated nausea (p=0.01) and body aches (p=0.03). Subjective comfort scores favored the ginger adjunct group. The diaphoretic effect of ginger was observed but did not translate into faster objective fever resolution.
