Song Jie (Knotty Pine Wood)

Chinese Herb Actions

Chinese Herb Dosage

• What is the typical dosage of Song Jie?

  10–15 g in decoction (Chen & Chen), with Bensky giving 9–15 g — a close agreement, and an unremarkable mid-range dose for this category. The material is hard, resinous timber, so it is broken or chipped small before use; whole knots are not extractable.

  • Decoction — 10–15 g (Chen & Chen); 9–15 g (Bensky). Both ranges are held on this record.
  • Medicinal wine — steeping in wine is the traditional preparation most often associated with pine knot for chronic wind-damp joint pain, consistent with a resinous material whose constituents are not water-soluble. Recorded as a classical preparation, not as a home method.
  • External use — decoctions of wind-damp herbs in this group are also used as washes and soaks. Recorded as traditional practice.

Chinese Herb Contraindications & Cautions

• Are there cautions for Song Jie?

  Our record states “none noted,” and no specific traditional contraindication could be verified in the sources consulted. That is consistent with a mild, narrowly used herb given in modest doses. The sensible cautions are the category ones and one practical one.

  • Yin deficiency and blood dryness — the standard caution for the wind-damp dispelling category. These herbs are warm and drying by design, so a pattern of dryness or heat is the wrong setting for them. Best used under a qualified practitioner.
  • Pregnancy — no specific traditional prohibition is recorded for Song Jie. Warming, dispersing herbs are conventionally used in pregnancy only under professional supervision.
  • Resin sensitivity — this is a resin-saturated wood, and pine resin components (colophony and abietic-acid derivatives) are a well-recognised contact allergen. Relevant mainly to anyone with known pine or rosin sensitivity, and mainly for external preparations. A practical note, not a documented case series for this herb.
  • Very little is documented either way — there is no clinical safety evaluation of Song Jie. “None noted” reflects an absence of reports, not the result of testing, and it would be dishonest to present it as the latter.

Chinese Herb Toxicity & Overdose

• Is Song Jie toxic?

  No. Our record’s toxicity entry reads “none noted,” the herb is not classed among the toxic materia medica, and no poisoning report or organ-toxicity finding for pine knot wood could be found in the sources consulted. Chemically it is a woody, resinous material dominated by diterpene resin acids and lignans — compound classes that are ubiquitous in softwood and in pine-derived food and industrial products.

  As with the cautions above, this is an absence of reports rather than a completed safety evaluation. No formal toxicology study of this herb exists in the accessible literature.

Western / Biomedical Research

Chinese Herb Clinical Studies & Research

Provided as research context — a summary of published biomedical study, not a therapeutic or medical claim.

• Is there modern research on Song Jie (Lignum Pini Nodi)?

  Barely any — and it is more useful to say so than to pad the page. There are no clinical trials of Song Jie, no animal study of its traditional indication, and no pharmacological work at all on joint pain or painful obstruction. What exists is a small amount of recent phytochemistry, and it points somewhere the tradition never does.

  • The only research on this exact drug — a group at the Institute of Materia Medica, Chinese Academy of Medical Sciences, published two 2025 papers isolating new abietane-type diterpenes from Pini Lignum Nodi, explicitly defined as the dried tuberculate or branched nodes of Pinus massoniana Lamb. Three compounds named pinusins A–C were reported alongside known diterpenoids, a flavonoid and a monoterpene, several of which protected HepG2 liver cells from paracetamol-induced damage (PMID 40183548; DOI 10.1080/10286020.2025.2481289); a companion paper reported pinusins D–F with twelve further known diterpenes, most showing protection against hydrogen-peroxide oxidative damage in the same cell line (PMID 40396928; DOI 10.1080/10286020.2025.2506527). Both are isolated-compound cell studies, and both concern liver protection — not pain, not joints.
  • Related but different material — European pine knots. Pine knots generally are a rich source of lignans, and the well-studied example is nortrachelogenin, found in knot extracts of Pinus sylvestris (Scots pine). It reduced inflammatory mediators in murine macrophages and reduced carrageenan-induced paw swelling in mice (PMID 27737478), and attenuated fibrosis-related macrophage activation in a further study (PMID 30458613). Maritime pine (Pinus pinaster) knots have been fractionated for the same polyphenol classes (PMID 31970869), and softwood knot lignans characterised analytically (PMID 38138599). These are different pine species and mostly a wood-chemistry and food-science literature, not studies of the Chinese medicinal. They establish that pine knots contain anti-inflammatory lignans; they do not establish anything about Song Jie.

  Honest summary: Song Jie is a minor herb with a thin evidence base. The traditional indication is untested, the only research on the drug itself is preliminary phytochemistry aimed at the liver, and the anti-inflammatory pine-knot literature belongs to other species. Nothing here supports a therapeutic claim, and the page would be worse, not better, for pretending otherwise.

Chinese Herb Notes

• What other pine medicinals are there, and which does this site hold?

  Pine yields several distinct medicinals, and Song Jie is the only one we currently hold. Saying so plainly is more useful than implying a fuller pine section exists. The others turn up regularly in the materia medica and in product listings, so it is worth knowing what they are and that they are not this herb.

  • Song Jie (this page, Lignum Pini Nodi) — the resinous knot wood; bitter, warm; Liver channel; wind-damp joint pain. Held on this site.
  • Song Xiang (Pini Resina, rosin or colophony) — the purified resin tapped from the tree, used chiefly as a topical for sores, carbuncles and skin lesions. A different part, a different preparation and a different clinical brief. Not held.
  • Song Hua Fen (Pini Pollen, pine pollen) — the pollen, used topically as a drying powder for weeping skin lesions and as a tonic in some traditions. Not held.
  • Song Zi Ren (pine nut) — the edible seed, a moistening food-herb for dry constipation and dry cough. Not held.

  A pinyin collision worth flagging: Gan Song, which we do hold, is Nardostachys root and rhizome — a fragrant qi-regulating herb with no botanical relationship to pine at all. The shared syllable is coincidence. Within the wind-damp category itself, Song Jie’s nearer neighbours on this site are herbs such as Hai Feng Teng and Hai Tong Pi, which occupy the same cold-damp joint-pain territory with rather more clinical prominence.

  Formula context: our own formula records do not currently link Song Jie to any formula, so no formula is named here. That is consistent with its status: a supporting herb, not a chief.

  Identity note flagged, not corrected: the Chinese characters on this record read 由松结. The expected characters for this herb are 松节 (sōng jié, “pine node”), matching the tone-marked pinyin already held on the record and the pharmaceutical Latin Lignum Pini Nodi. The leading character 由 appears to be stray, and 结 is a different character from 节. We have left the field exactly as held and report it here rather than changing it. This is an owner decision.
