What are the morphological characteristics of this plant?
Lycopus lucidus has quadrangular, opposite leaves with serrated margins and small, inconspicuous white flowers arranged in dense axillary whorls. The stems are typically erect and square in cross-section, a characteristic common to many members of the Lamiaceae family. Its leaf blades are generally lanceolate or ovate, tapering toward the apex to create a pointed appearance. The plant often features a woody base as it matures, providing structural support for its herbaceous upper growth. Fine pubescence may be present on the stems and leaf surfaces, contributing to its tactile texture.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of the Americas, specifically ranging from Mexico through Central America into parts of South America. It typically flourishes in humid, lowland environments where moisture is abundant. Many specimens are found growing along the margins of rivers, streams, and other freshwater habitats. The species often occupies niches within disturbed forest edges or wetlands. Its presence is most frequent in areas characterized by consistent warmth and high annual rainfall.
How is this plant cultivated?
This plant requires consistent moisture and well-drained, nutrient-rich soil to thrive in temperate or subtropical environments.
Growers should ensure the cultivation site receives ample sunlight, though partial shade can help prevent leaf scorch in hotter climates. Regular watering is essential to mimic its natural riparian habitat and prevent the soil from drying out completely. Maintaining a stable temperature range will encourage vigorous vegetative growth throughout the growing season.
Once established, the plant is relatively hardy and requires minimal intervention beyond routine hydration and occasional weeding.
What parts of this plant are used medicinally?
This plant Lycopus lucidus is used medicinally primarily through its leaves. These green leaves contain various phytochemicals that are believed to offer therapeutic benefits. People often prepare extracts or infusions from the foliage to treat specific ailments. The application of these herbal preparations can vary depending on traditional practices. Such uses highlight the importance of the leaf in the plant's medicinal profile.
According to a study published by "Journal of agricultural and food chemistry", the leaves of Lycopus lucidus Turcz are used to produce an herbal tea containing water-soluble polysaccharides. These polysaccharides are mainly composed of galactose at 50.1 mol % and galacturonic acid at 14.2 mol %, which together account for 64.3 mol % of all nine quantitative monosaccharides. In studies involving mice, administration of low-dose (50 mg/kg), intermediate-dose (100 mg/kg), and high-dose (300 mg/kg) of these polysaccharides occurred once daily for 30 consecutive days. The results showed that these polysaccharides significantly enhanced plaque-forming cells, serum hemolysin levels, and delayed-type hypersensitivity (p < 0.01). Additionally, the intermediate- and high-dose treatments caused a significant increase in the indices of the thymus and spleen organs (p < 0.05).

What are the pharmacological activities of Lycopus lucidus?
This plant has pharmacological activities including blood-circulation-promoting effects, removal of blood stasis, platelet aggregation inhibition, wound healing promotion, and immunomodulatory actions. Its ability to enhance blood flow and clear stagnation makes it a significant candidate for treating circulatory disorders. By inhibiting platelet aggregation, the plant helps prevent the formation of harmful clots within the vascular system. Furthermore, its properties support the physiological processes required for effective wound healing in damaged tissues. These combined effects are further enhanced by its capacity to modulate the immune system to maintain biological balance.
According to a study published by "Phytomedicine : international journal of phytotherapy and phytopharmacology", the aqueous extract of Lycopus lucidus Turcz ameliorates streptozocin-induced diabetic renal damage by inhibiting the TGF-β1 signaling pathway. In SV40 MES13 cells, Lycopus suppressed rhTGF-β1-induced Smad2 and ERK1/2 activation and down-regulated the expression of TGF-βRI, TGF-βRII, Smad4, and Smad7 without inhibiting cell viability. In vivo, the plant inhibited Smad2 phosphorylation and reduced the mRNA level of TGF-β1. This extract also ameliorated the expansion of the mesangial area in glomerular tissue while reducing serum levels of Scr and BUN and total-SOD activity in STZ-induced diabetic rats. Lycopus acts as a novel inhibitor of renal fibrosis by blocking the TGF-β signaling pathway to provide a protective effect against renal damage.
The primary pharmacological activities of this plant are shown in the list below.
- blood-circulation-promoting
- removing blood stasis
- promoting blood circulation
- platelet aggregation inhibition
- wound healing

What health conditions is this plant used for?
This plant is used for gynecological diseases, irregular menstruation, menstrual pain, kidney disease, and renal damage. It serves as a traditional remedy to help regulate menstrual cycles and alleviate the discomfort of painful periods. Additionally, its properties are utilized to support urinary health and manage various issues related to the kidneys. The plant is often employed specifically to address cases of renal damage and restore function to the urinary system.
According to a study published by "Evidence-based complementary and alternative medicine : eCAM", Lycopus lucidus is traditionally used in Asia to treat edema, wound healing, and gynecological diseases like irregular menstruation and menstrual pain. The study hypothesized that this plant could decrease the risk of developing osteoporosis. Researchers tested a water extract of Lycopus lucidus in an ovariectomized rat model using doses of 15.2 mg/kg (wLL-L) and 152 mg/kg (wLL-H). These drugs were administered orally once daily for 9 weeks. The results indicated that the extract inhibits osteoclastogenesis and prevents the loss of the trabecular area in the femur.
The main health conditions this plant is used for are shown in the list below.
- gynecological diseases

What side effects this plant can have?
This plant can cause platelet aggregation inhibition and prolonged blood coagulation time in humans. These physiological changes may increase the risk of excessive bleeding or bruising during medical procedures. Because the plant affects how blood clots, individuals taking anticoagulant medications should exercise extreme caution. It is important to monitor for any signs of internal or external hemorrhage after consumption. Consult a medical professional before using this species for any therapeutic purpose.
According to a study published by "Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials", two extracted fractions from Lycopus lucidus, known as F04-A and F04-B, were analyzed for their effects on coagulation. These two fractions, F04-A and F04-B, could inhibit platelet aggregation in rats in vitro and in mice in vivo. Additionally, these fractions could prolong the blood coagulation time in mice. Despite these effects, F04-A and F04-B had no effect on bleeding time. The study suggests the activity of F04-A was probably stronger than that of F04-B in inhibiting platelet aggregation and blood coagulation.
The main side effects this plant can have are shown in the list below.
- platelet aggregation inhibition
- prolonged blood coagulation time
What herbs are paired with Lycopus lucidus?
