What are the morphological characteristics of this plant?

Angelica glauca has a perennial rootstock that produces upright, hollow stems reaching up to 100 centimeters in height with lanceolate, glaucous leaves arranged alternately along the stalk. The foliage consists of large, compound leaves that are deeply divided into narrow, linear segments with a distinct bluish-green hue. Small, white flowers are clustered in dense, compound umbels that sit atop the sturdy stems during the blooming season. These inflorescences are supported by peduncles that lack the heavy pubescence found in related species. The overall structure of the plant is characterized by its robust, erect growth habit and smooth, waxy leaf surfaces.

What is the geographical distribution of this plant?

This plant is native to the subarctic and arctic regions of North America, spanning from Alaska across much of Canada and into the northernmost parts of the United States. It thrives primarily in tundra ecosystems and alpine environments where rocky or gravelly soils are present. Its distribution is closely tied to cold, high-latitude climates and high-altitude mountain ranges. Many populations are found in moist meadows or near stream banks within these northern territories. The species occupies a niche specifically adapted to the harsh, sparsely vegetated landscapes of the far north.

Evidence Level: ★☆☆☆☆

How is this plant cultivated?

This plant requires well-drained, sandy or gravelly soil and a cool, temperate climate to thrive in rocky alpine environments.

It should be sown directly into its permanent location because the root system is highly sensitive to transplanting. Full sun to partial shade is ideal for promoting healthy foliage development throughout the growing season. Regular moisture is necessary, but the substrate must never remain waterlogged to prevent root rot.

Once established, this hardy perennial is relatively low-maintenance and can withstand significant temperature fluctuations.

What parts of this plant are used medicinally?

This plant provides medicinal value through its leaves, roots, seeds, and stems. The roots are frequently harvested for their potent bioactive compounds used in traditional remedies. Leaves are often utilized in infusions or topical applications to address specific ailments. The seeds contain essential oils that contribute to the plant's therapeutic properties. Additionally, the stem can be processed to extract various medicinal constituents.

According to a study published by "International journal of molecular sciences", Angelica glauca is an endangered medicinal and aromatic herb containing bioactive metabolites like terpenoids, phenolics, and phthalides. Spatial transcriptome sequencing of the leaf, stem, and root generated 109 million high-quality paired-end reads which were assembled into 81,162 unigenes. The study identified 1136 differentially expressed unigenes that were grouped into four subclusters across the leaf, stem, and root tissues. Analysis showed higher contents of limonene and phthalide compounds in the roots, whereas ferulic acid accumulated more in the stem than in the root and leaf tissues. The root is suggested as the primary site of phthalide biosynthesis due to specific expressions of NADPH-AOR, SDMs, PKC, and CYP72A15.

What are the pharmacological activities of Angelica glauca?

This plant has demonstrated significant pharmacological potential through its documented anti-inflammatory, antibacterial, anticancer, antioxidant, and gastroprotective activities. The antioxidant properties of Angelica glauca help neutralize harmful free radicals within biological systems. Its antibacterial effects allow it to combat various pathogenic microorganisms effectively. Additionally, the plant exhibits anticancer capabilities that may inhibit the growth of malignant cells. Finally, its gastroprotective mechanisms provide a defense against stomach lining damage and ulceration.

According to a study published by "Fitoterapia", the root extract of Angelica glauca exhibits potent antioxidant activity at 68 μg/mL and was found to be non-toxic in acute oral toxicity tests in rats. In ethanol-induced gastric ulcer models, a dose of 500 mg/kg significantly reduced the ulcer-index, enhanced gastric pH, and reduced pepsin levels. At a 500 mg/kg dose, SOD, CAT, GSH and LPO levels were 173 U/g, 78 U/g, 195 μM GSH/g and 194 nM MDA/g of tissue, respectively. The treatment reduced IL-6 levels by 31.2 % at 500 mg/Kg and 57.1 % at 250 mg/Kg, while TNF-α concentration was reduced by 32 % and 60 % at those same doses. These results highlight the gastroprotective efficacy of the plant due to its antioxidant and anti-inflammatory properties.
