What are the morphological characteristics of this plant?

Lithospermum officinale has erect, hairy stems that reach heights of 30 to 60 centimeters and bear alternate, lanceolate leaves with entire margins. The foliage is typically dark green and possesses a rough, scabrous texture due to fine hairs covering the surface. Small, funnel-shaped flowers emerge from the leaf axils, displaying a white or pale pink corolla with five lobes. These blossoms eventually develop into small, globular nutlets that are characterized by a hard, stony texture. The plant's root system consists of a thick, woody taproot that anchors the structure firmly in the soil.

How is this plant cultivated?

This plant, commonly known as gromwell, thrives in well-drained, loamy soils with a neutral to slightly alkaline pH and requires full sun to partial shade for optimal development.

Growers should sow seeds in late summer or early autumn to allow for natural stratification during the winter months. Maintaining consistent moisture without waterlogging the roots is essential for preventing fungal diseases in the soil. Once established, the plant is relatively hardy and requires minimal fertilization to produce its characteristic blue flowers.

Regular weeding around the base helps the slow-growing root system compete effectively for nutrients.

What parts of this plant are used medicinally?

This plant Lithospermum officinale provides medicinal value through its root, leaf, and stem. The root is most commonly harvested and utilized in traditional remedies for its perceived healing properties. Additionally, the leaves can be incorporated into various topical or internal preparations. Even the stem contains specific compounds that contribute to the plant's overall therapeutic profile. These different components are often processed together to create traditional herbal extracts.

According to a study published by "Applied biochemistry and biotechnology", the extract of Lithospermum officinale (CAS 90063-58-4) is used in both medicinal and cosmetic industries. While the cultivation of the plant takes at least 2 years to produce usable crops, its callus culture proliferated 8.3 times with 4.9-fold biomass in less than 30 days. The total phenolic content and antioxidant capacity of the proliferated cell extracts were similar to those of the extracts of the natural plant tissues, in particular from the root. These results support the idea that the extract of Lithospermum officinale cells can be a reliable substitute for the extract of the natural plant tissues.

What are the pharmacological activities of Lithospermum officinale?

This plant has diverse pharmacological activities including anti-cancer, anti-inflammatory, antimicrobial, antioxidant, and wound healing acceleration properties. Its natural compounds function by neutralizing free radicals to reduce oxidative stress within biological systems. These chemical constituents also inhibit the growth of various pathogenic microorganisms and mitigate inflammatory responses in damaged tissues. Furthermore, the plant promotes cellular regeneration to facilitate the rapid closure of skin lesions. Research continues to explore how these specific mechanisms can be utilized in modern therapeutic applications.

According to a study published by "Current pharmaceutical biotechnology", Lithospermum officinale is a medicinal herb that produces secondary metabolites with antioxidant, antimicrobial and/or anti-cancer effects. Methanolic extracts of 17-day-old Lithospermum officinale callus exhibited anti-inflammatory effects on LPS-stimulated microglial cells much higher than those observed for CfA. When activated microglial cells were pretreated with an effective dose of 0.8 mg mL-1 of LoE, there was a decreased expression of Nos2, Tnf-α, and Cox-2 mRNA along with the suppression of TNF-α and IL-1β release. The methanolic extract of 17 and 31-day-old callus was evaluated for its capacity to act on primary microglia obtained from neonatal Wistar rats that were 1 to 3-days old. Because the LoE extract shows a high antioxidant capacity and lacks PzAl, it is anticipated to be a reliable substitute for the preparation of neuroprotective pharmaceutical formulas.

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

  • anti-cancer
  • anti-inflammatory

What medicinal compounds this plant contains?

This plant contains the medicinal compounds shikonin, lithospermic acid, chlorogenic acid, pyrrolizidine alkaloids, and various quinones. The naphthoquinone derivative shikonin and its related alkanin are primary active constituents responsible for the plant's distinct red pigment and healing properties. Additionally, the presence of lithospermic acid and chlorogenic acid contributes to its complex chemical profile. Certain quinones within the roots provide significant biological activity used in traditional applications. However, the inclusion of pyrrolizidine alkaloids necessitates careful handling due to potential toxicity concerns.

According to a study published by "Planta medica", Lithospermum officinale is a valuable source of bioactive metabolites with medicinal and industrial values. Researchers used over 4Gbps of RNA-sequencing datasets to obtain a de novo transcriptome assembly consisting of 77,047 unigenes with an assembly N50 value of 1524 bps. Among these, 52,766 unigenes were assigned putative gene functions, gene ontology terms, and KEGG pathways. The study identified 20 unigenes representing enzymes of the lithospermic/chlorogenic acid biosynthesis pathway and 48 unigenes for the shikonin biosynthesis pathway. Additionally, 15 candidate unigenes were annotated as cytochrome P450 with the highest expression in the root for key biochemical reactions toward shikonin biosynthesis.

What side effects this plant can have?

This plant can cause pyrrolizidine alkaloid toxicity, a condition that leads to severe liver damage and potential cancer. Consumption of the herb is also linked to a decline in endogenous thyroid stimulating hormone levels. This hormonal shift occurs due to the inhibition of peripheral thyroxine deiodination within the body. Such disruptions to the endocrine system can interfere with normal metabolic functions. Consequently, these cumulative physiological impacts make the plant potentially hazardous to human health.

According to a study published by "Current pharmaceuctical biotechnology", Lithospermum officinale is a medicinal herb that faces therapeutic limitations due to the presence of pyrrolizidine alkaloids (PzA) in its root extract. This research focused on the methanolic extracts of 17 and 31-day-old Lithospermum officinale callus to evaluate anti-inflammatory capacity. The methanolic extract of the 17-day-old callus exhibited anti-inflammatory effects on LPS-stimulated microglia much higher than those observed for CfA. An effective dose of the Lithospermum officinale callus extract (LoE) was identified as 0.8 mg mL-1. Because the LoE shows a high antioxidant capacity and lacks PzA, it is anticipated to be a reliable substitute for preparing neuroprotective pharmaceutical formulas.

The main side effects this plant can have are shown in the list below.

  • pyrrolizidine alkaloids toxicity
  • decline in endogenous thyroid stimulating hormone levels
  • inhibition of peripheral thyroxine deiodination
