Medicinal plants have long been used in traditional medicine to support wound repair and control bleeding. Among these, Symphytum officinale L. (comfrey) is widely used in European traditional medicine for the treatment of wounds, fractures, and soft tissue injuries. However, the pharmacological basis of these effects and the contribution of different plant organs remain insufficiently understood. The aim of this study was to characterize the phytochemical composition of extracts obtained from different organs of S. officinale and to evaluate their hemostatic and wound-healing activities in vivo, in order to identify the most active plant parts. Extracts from the roots, leaves, and flowers of S. officinale were prepared using solvents of different polarity. Phytochemical composition was analyzed by spectrophotometric assays and UPLC\u2013MS\/MS. Hemostatic and wound-healing activities were evaluated in vivo in rats, and cytological analysis of wound exudate was performed. Distinct organ-specific differences in phytochemical composition were observed, with leaf and flower extracts richer in phenolic compounds and amino acids, while root extracts contained higher levels of pyrrolizidine alkaloids. Leaf (S7) and flower (S13) extracts showed the strongest biological activity. S13 accelerated wound healing, achieving complete wound closure by day 10 compared with day 12 in the reference group, while S7 exhibited the most pronounced hemostatic effect, reducing bleeding cessation time to 44.3 s compared with 64.1 s for the reference preparation and 144.3 s for the control group. Cytological analysis indicated reduced inflammation and enhanced fibroblast activity. The findings support the traditional use of S. officinale in wound treatment and highlight the importance of organ-specific phytochemical composition. Aerial parts showed strong wound-healing and hemostatic effects, suggesting their relevance alongside the traditionally used root and supporting the involvement of multiple constituents in the observed biological activity. The study provides new insights into the organ-specific phytochemical composition and biological activity of S. officinale, thereby supporting further research on the therapeutic potential of its aerial parts.<\/jats:p>","DOI":"10.3390\/molecules31122159","type":"journal-article","created":{"date-parts":[[2026,6,19]],"date-time":"2026-06-19T09:18:43Z","timestamp":1781860723000},"page":"2159","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Organ-Specific Phytochemical Profiles, Wound-Healing and Hemostatic Activities of Symphytum officinale Aerial Parts and Roots with Differential Pyrrolizidine Alkaloid Content"],"prefix":"10.3390","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-3094-3737","authenticated-orcid":false,"given":"Getter","family":"Dolgo\u0161ev","sequence":"first","affiliation":[{"name":"Institute of Pharmacy, Faculty of Medicine, University of Tartu, 50411 Tartu, Estonia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1556-5085","authenticated-orcid":false,"given":"Yurii M.","family":"Kolesnyk","sequence":"additional","affiliation":[{"name":"Zaporizhzhia State Medical and Pharmaceutical University, 69035 Zaporizhzhia, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7339-7078","authenticated-orcid":false,"given":"Olha","family":"Hancheva","sequence":"additional","affiliation":[{"name":"Zaporizhzhia State Medical and Pharmaceutical University, 69035 Zaporizhzhia, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6102-3455","authenticated-orcid":false,"given":"Oleksandr","family":"Panasenko","sequence":"additional","affiliation":[{"name":"Zaporizhzhia State Medical and Pharmaceutical University, 69035 Zaporizhzhia, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3704-5539","authenticated-orcid":false,"given":"Andrii","family":"Kaplaushenko","sequence":"additional","affiliation":[{"name":"Zaporizhzhia State Medical and Pharmaceutical University, 69035 Zaporizhzhia, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9742-0284","authenticated-orcid":false,"given":"Roman","family":"Shcherbyna","sequence":"additional","affiliation":[{"name":"Zaporizhzhia State Medical and Pharmaceutical University, 69035 Zaporizhzhia, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7627-6263","authenticated-orcid":false,"given":"Valdas","family":"Jak\u0161tas","sequence":"additional","affiliation":[{"name":"Institute of Pharmaceutical Technologies, Lithuanian University of Health Sciences, LT-44307 Kaunas, Lithuania"},{"name":"Department of Pharmacognosy, Lithuanian University of Health Sciences, LT-44307 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vaidotas","family":"\u017dvikas","sequence":"additional","affiliation":[{"name":"Institute of Pharmaceutical Technologies, Lithuanian University of Health Sciences, LT-44307 Kaunas, Lithuania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5559-5476","authenticated-orcid":false,"given":"Ivo","family":"Laidm\u00e4e","sequence":"additional","affiliation":[{"name":"Institute of Pharmacy, Faculty of Medicine, University of Tartu, 50411 Tartu, Estonia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5996-5144","authenticated-orcid":false,"given":"Jyrki","family":"Hein\u00e4m\u00e4ki","sequence":"additional","affiliation":[{"name":"Institute of Pharmacy, Faculty of Medicine, University of Tartu, 50411 Tartu, Estonia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9545-8548","authenticated-orcid":false,"given":"Oleh","family":"Koshovyi","sequence":"additional","affiliation":[{"name":"Institute of Pharmacy, Faculty of Medicine, University of Tartu, 50411 Tartu, Estonia"},{"name":"Zaporizhzhia State Medical and Pharmaceutical University, 69035 Zaporizhzhia, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8731-7366","authenticated-orcid":false,"given":"Ain","family":"Raal","sequence":"additional","affiliation":[{"name":"Institute of Pharmacy, Faculty of Medicine, University of Tartu, 50411 Tartu, Estonia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1441","DOI":"10.1002\/ptr.4612","article-title":"Comfrey: A Clinical Overview","volume":"26","author":"Staiger","year":"2012","journal-title":"Phytother.
