Scientific fungus specimen plate of White Indian Bread, Wolfiporia extensa, showing white inner sclerotium sections and diagnostic material details.
Botanical plate by Kodi .

Known in TCM as Bai Fu Ling (白茯苓), this sweet and bland, neutral herb enters the Heart, Spleen, and Kidney. Traditionally, it strengthens the Spleen and gently leaches dampness ... Bai Fu Ling is used for loose stool, poor appetite, fullness, and fatigue when weak transport allows dampness to accumulate, most often applied for diarrhea, poor appetite, and insomnia. Modern research has identified Poria among its active constituents.

Part used: Sclerotium (fungus)

Traditional Use

Primary Actions

  • Strengthens the Spleen and gently leaches dampness ... Bai Fu Ling is used for loose stool, poor appetite, fullness, and fatigue when weak transport allows dampness to accumulate.
  • Calms the Heart and settles the spirit ... traditional use includes palpitations, insomnia, and restlessness when deficiency and phlegm-damp disturb the Shen.
  • Represents the inner white sclerotium lane of the Poria family ... it is generally treated as milder and more middle-supportive than the peel-focused or strongly damp-draining parts.

Secondary Actions

  • This page should not be collapsed into the broader already-live `indian-bread` record, the edema-focused peel `Fu Ling Pi`, or the spirit-rooted `Fu Shen` lanes ... all belong to the Poria family, but the medicinal emphasis differs.
  • Bai Fu Ling is especially associated with the pale inner medicinal blocks shown in the illustration workflow rather than the whole rough sclerotium.

Classic Formulas

  • Shen Ling Bai Zhu San ... classic digestive-deficiency formula in which Bai Fu Ling strengthens the middle and helps stop chronic damp diarrhea.
  • Gui Pi Tang ... formula context emphasizing the Heart-Spleen support and spirit-calming side of the Poria family.
  • Ling Gui Zhu Gan Tang and related damp-retention formulas ... when dizziness, fullness, and weak transformation are tied to retained fluids.

Classical References

  • Traditional references describe Bai Fu Ling within the larger Fu Ling family as sweet, bland, and neutral, with a particular reputation for supporting the Spleen while calming the mind.
  • Part-specific Poria usage is an old pharmacy distinction ... the white inner portion is not treated as identical in emphasis to the peel, hostwood, or spirit-root sections.

Modern Research

Active Compounds

  • Poria polysaccharides ... the best known immune and gut-focused research fractions in the Wolfiporia literature
  • Triterpenoids such as pachymic acid and poricoic acids ... key lipophilic constituents in broad Poria pharmacology
  • Sterols including ergosterol derivatives ... supportive fungal constituents discussed in anti-inflammatory research
  • Small metabolites including adenosine-related compounds ... contributors to sedative and metabolic discussion

Studied Effects

  • A 2024 review summarized traditional uses, triterpenoid chemistry, and renoprotective pharmacology of Poria cocos, reinforcing the broad modern interest around the Fu Ling family even though most studies do not isolate Bai Fu Ling as a separate laboratory entity (PMID 39482471).
  • A 2022 review outlined the traditional usages, chemical components, and pharmacological activities of Wolfiporia cocos, again showing that modern evidence largely supports the overall medicinal mushroom family rather than only one commerce cut (PMID 35300566).
  • A 2022 nomenclature review clarified the correct scientific naming around Fuling medicinal mushroom, which matters for accurate botanical attribution of Bai Fu Ling pages and related Poria records (PMID 35938080).

Safety & Interactions

Contraindications

  • Profound fluid depletion or yin dryness without damp retention
  • Clear qi sinking without dampness or phlegm

Cautions

  • Bai Fu Ling is generally gentle, but concentrated extracts and commercial supplements are not equivalent to ordinary decoction pieces.
  • Much of the research literature studies isolated polysaccharides or triterpenes from the broader Poria family rather than the inner white portion alone.
