Boletus Laricis: Larch Polypore for Liver and Fever

What Is Boletus Laricis?

Boletus Laricis is a homeopathic remedy prepared from the larch polypore fungus (Laricifomes officinalis, historically classified as Boletus laricis or Agaricus laricis), a distinctive shelf fungus that grows on larch trees. Used medicinally since antiquity — known as agaric of the oak or white agaric — it was official in European pharmacopoeias for centuries as a powerful purgative and emetic. Clarke includes Boletus Laricis in the Dictionary of Practical Materia Medica with indications that reflect this traditional cathartic action alongside its homeopathic proving picture of hepatic and febrile conditions.

Key Characteristics

• Intermittent fever — bilious, remittent fevers with the characteristic periodicity and hepatic involvement
• Hepatic congestion — liver enlargement and tenderness with bilious symptoms
• Profuse sweating — particularly night sweats accompanying the febrile and hepatic picture
• Nausea and vomiting of a bilious character — yellow-green bile vomited during the febrile attack
• Diarrhoea with a bilious, yellow, watery character during the febrile episodes
• A profoundly debilitating action — the remedy picture is one of exhausting, depletive illness
• Worse from touch to the liver region; better after vomiting and purging

Mental Picture

Clarke notes that the mental picture accompanying Boletus Laricis is one of profound debility and despondency during the febrile and bilious attacks. The patient is exhausted, prostrate, and indifferent. Between attacks, the recovery is incomplete and the debilitation persists. The mental state reflects the draining quality of the febrile and hepatic illness rather than providing an independent psychiatric keynote.

Physical Picture

Intermittent bilious fever with hepatic congestion is the central picture. The fever has a periodic, remittent character. Profuse sweating — debilitating and exhausting — accompanies the febrile phases. Bilious vomiting and yellow, watery diarrhoea during attacks reflect the hepatic involvement. The liver is enlarged and tender. The overall process is deeply depleting, leaving the patient progressively debilitated between attacks. Night sweats add to the exhaustion.

When Is It Considered?

Homeopaths may consider Boletus Laricis when:

• Intermittent bilious fever with a periodic, remittent character is the clinical picture
• Hepatic congestion with liver tenderness accompanies the febrile attacks
• Profuse, exhausting night sweats accompany the febrile and hepatic picture
• Bilious vomiting and yellow, watery diarrhoea occur during the febrile episodes
• Progressive debilitation and incomplete recovery between attacks characterise the course
