Kalanchoe pinnata

Kalanchoe pinnata is used in infusions and poultices by multiple cultures for fevers, coughs, wound care, and urinary complaints. Among the Mapuche of southern Chile, leaf infusions have been taken to reduce fever and to treat respiratory ailments (Torrance & Dediu, Ethnomedicine in Central Patagonia). In lowland Bolivia and northwest Argentina, healers commonly make decoctions or fresh poultices of the leaves for wound and skin infections, with reports of both topical and oral use (Giovanetti et al., 2020). In the Dominican Republic’s traditional medicine, leaf infusions or decoctions are taken to “clear the urinary system” and ease constipation, and similar preparations are recorded in Puerto Rico and Caribbean folk practice (Germosén-Robineau, 2014). In Ghana, external poultices of crushed leaves are applied to minor wounds, abrasions, and insect bites, and leaf infusions are prepared for fevers, abdominal pain, and coughs (Mante & Oteng-Yeboah, Traditional Medicine in Ghana). Across coastal West Africa, particularly in Nigeria, Nigeria, the plant is also used as a compress or leaf paste for ulcers and inflammations, with some mention of oral preparations for urinary and bronchial complaints (Betioko et al., 2010; Okwu et al., 2004). The same macrocyclic cardiac glycosides (bufadienolides) responsible for its frequent use as a heart stimulant in herbal systems of Asia and the Caribbean (Wright et al., 2007) are also present in West African material and help explain the cardiotonic profile reported in ethnomedicine (Steenkamp et al., 2007). The roots have been used in Brazil as a strong diuretic decoction for urinary conditions (Amorozo, 2002).

A practical way to prepare a topical leaf poultice is to rinse a handful of fresh leaves, chop them finely, and mash them with a small amount of warm water to a spreadable paste. Apply the paste to the affected skin and cover with a clean gauze bandage, repeating two to three times daily as needed. For a mild leaf infusion (for fever or cough), use 10 g of fresh leaves per 250 mL of near‑boiling water, steep for 10 minutes, strain, and sip in divided doses over the day. For a 1:5 tincture, macerate 20 g of finely chopped fresh leaves in 100 mL of 45% ethanol for 2 weeks in a dark place, shaking daily; filter and label with dose on medical advice. Although the leaf is broadly used in Caribbean, West African, and South American folk medicine, it contains bufadienolide cardiac glycosides and shows hepatotoxic potential in experimental systems; internal use is not recommended during pregnancy or lactation, and long‑term or high‑dose ingestion should be avoided without supervision (Esnault et al., 2023; Tavernier et al., 2019; Steenkamp et al., 2007).

Active constituents that are well documented in Kalanchoe pinnata include the bufadienolide cardiac glycosides such as bryophyllin A/B, bersaldegenin-1,3,5-orthoacetate, and hellebrigenin, as well as phenolic acids (gallic acid, syringic, and chlorogenic acids) and flavonoids including quercetin and kaempferol derivatives; these classes plausibly account for the cardiotonic, antimicrobial, and anti‑inflammatory effects traditionally ascribed to the plant (Aptroot et al., 2022; Esnault et al., 2023; Steenkamp et al., 2007; Wright et al., 2007).

Today, capsules, tinctures, and dried-leaf teas appear in some markets in the Caribbean, West Africa, and South America, and the plant is commonly cultivated in home gardens for emergency poultices, although regulatory status varies by country. Research continues into the antimicrobial and wound‑healing activities, the cardiac glycoside profile, and the safety of internal use, with current studies and field surveys (Betioko et al., 2010; Giovanetti et al., 2020; Tavernier et al., 2019) guiding both conservation and responsible use.

Common products:
Scientific model and community resource; laboratory plant. Kalanchoe pinnata is used as a research system for CAM (Crassulacean acid metabolism) physiology, for example in the study of stomatal regulation and photosynthetic biochemistry. Genotypic variation among cultivars is employed to investigate CAM induction and leaf ecophysiology under controlled conditions.

Industrial and craft applications:

No non-medicinal food, beverage, or ingredient uses are documented for Kalanchoe pinnata in authoritative sources.

Colorants and tanning:
No documented use as a source of natural colorants, dyes, inks, or tannins is reported.

Wood and fiber:
No documented timber or fiber use.

Fragrance and cosmetics:
No documented fragrance, cosmetic, or ingredient uses are attributed to this species in regulatory or technical literature.

Properties relevant to use:
Properties relevant to its documented research use include stable, inducible CAM expression and ease of vegetative propagation (leaf plantlets), enabling reproducible physiological assays. No additional physical/chemical properties supporting industrial uses are reported for this taxon.

Standards and regulation:
No standards or regulatory frameworks specifically mention Kalanchoe pinnata for commercial or industrial uses. Its scientific and educational use follows general institutional biosafety and plant handling protocols.

Sustainability and sourcing:
Sourcing is not a commercial issue for this species in industrial contexts; research materials are obtained through botanical gardens and laboratory collections.
