What are the morphological characteristics of this plant?

Populus lasiocarpa has deciduous, ovate to broadly elliptic leaves with serrated margins, a single woody stem, and small, inconspicuous yellowish flowers. The foliage is characterized by finely serrated edges and a texture that varies depending on the season. Its bark typically transitions from a smooth, grayish surface in younger specimens to a more deeply furrowed texture as the tree matures. The species produces small, wind-dispersed seeds attached to long, silky hairs that facilitate movement through the air. These morphological features collectively allow the plant to thrive in riparian environments and disturbed habitats.

Evidence Level: ★☆☆☆☆

What is the geographical distribution of this plant?

This plant is native to the western regions of North America, ranging from southern Alaska and the Yukon through western Canada and into the northwestern United States. It thrives primarily in mountainous areas and high-altitude environments where soil moisture is consistent. Its distribution is often concentrated along riparian zones and riverbanks within subalpine and montane ecosystems. You can commonly find these trees in the Rocky Mountains, the Cascade Range, and the coastal mountains. The species prefers cool, temperate climates found throughout the Pacific Northwest and the interior West.

Evidence Level: ★☆☆☆☆

How is this plant cultivated?

This plant, commonly known as the quaking aspen, is cultivated by planting clonal suckers or seeds in well-drained, moist, and fertile soils under full sunlight.

Growers typically prioritize sites with ample water availability to support its rapid growth rates and large leaf canopy. Because it spreads via underground rhizomes, managing these root systems is essential to prevent the plant from invading unintended areas. Young saplings require protection from heavy browsing by wildlife and consistent moisture during their initial establishment period.

Once mature, the species thrives in temperate climates and can be used for timber production or ornamental landscapes.

What parts of this plant are used medicinally?

This plant, Populus lasiocarpa, is utilized medicinally through its buds, bark, and leaves. The buds are frequently harvested to create salves or teas due to their specific chemical properties. Practitioners often use the bark to treat various ailments such as inflammation or digestive issues. Additionally, the leaves can be prepared into infusions for their soothing effects. These various components provide a versatile range of therapeutic applications for the species.

According to a study published by "Phytomedicine : international journal of phytotherapy and phytopharmacology", the leaf-buds of Populous lasiocarpa are used traditionally as anti-inflammarotary agents for the treatment of cough or skin injuries. These poplar leaf-buds, also known as Populi gemmae, were evaluated for their anti-inflammarotary activity and antioxidant properties. The study involved the assessment of extracts through bioautographic TLC tests using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and riboflavin-light blue tetrazolium chloride (riboflavin-light-NBT) radicals. While other species showed effects on interleukin 6 (IL-6) and interleukin IL-1β (IL-1β) levels, these specific effects were not observed for buds from P. lasiocarpa. Furthermore, the study noted that the effects related to the inhibition of COX-2 protein expression were not observed for P. lasiocarpa buds not containing of flavonoids.

What are the pharmacological activities of Populus lasiocarpa?

This plant has demonstrated significant pharmacological potential through its potent anti-inflammatory and antioxidant activities. Research indicates that the phytochemical constituents within Populus lasiocarpa work to inhibit pro-inflammatory mediators in biological systems. These bioactive compounds also effectively neutralize free radicals, which helps to reduce oxidative stress in cells. By mitigating both inflammation and oxidation, the plant offers a natural mechanism for protecting tissues from damage. Such properties suggest that its extracts could serve as valuable sources for developing new therapeutic agents.

According to a study published by "Phytomedicine : international journal of phytotherapy and phytopharmacology", Populus lasiocarpa leaf-buds are used traditionally as anti-inflammatory agents for the treatment of skin injuries or cough. The study evaluated the anti-inflammatory activity of leaf-buds extracts from P. lasiocarpa towards human gingival fibroblasts (HG_1) pro-inflammatory stimulated by silver nanoparticles (AgNPs). Antioxidant properties were assessed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and riboflavin-light blue tetrazolium chloride (riboflavin-light-NBT) radicals to determine radical scavenging properties. While several flavanones and phenolic acids with radical scavenging properties were revealed in all analyzed extracts, the specific protective effects observed in other species were not observed for buds from P. lasiocarpa not containing of flavonoids.

The primary pharmacological activities of this plant are shown in the list below.

  • anti-inflammatory
  • antioxidant

What medicinal compounds this plant contains?

This plant contains various bioactive constituents including flavonoids, phenolic acids, and terpenoids. These medicinal compounds are primarily concentrated within the bark and leaf tissues of the species. The presence of flavonoids provides significant antioxidant and anti-inflammatory properties to the plant. Additionally, specific phenolic compounds contribute to its potential antimicrobial activities. Researchers study these chemical profiles to understand how the plant might be used in traditional medicine.

According to a study published by "Phytomedicine : international journal of phytotherapy and phytopharmacology", the leaf-buds of Populous lasiocarpa are used traditionally as anti-inflammaroty agents for the treatment of skin injuries or cough. Phytochemical analysis revealed the presence of several flavanones and phenolic acids in all analyzed poplar bud extracts. However, the specific protective effects of pinocembrin and pinostrobin against AgNPs induced inflammation and cytotoxicity in HGFF-1 cells were not observed for buds from P. lasiocarpa. This lack of effect was due to the fact that the P. lasiocarpa buds did not contain flavonoids.
