What parts of this plant are used medicinally?

This plant, known as Amaranthus tricolor, utilizes its nutrient-dense leaves for various medicinal applications. These leaves are often consumed to provide essential vitamins and minerals that support overall bodily health. In traditional herbal practices, the leaf extracts are sometimes used to address inflammatory conditions or digestive issues. The presence of antioxidants within the foliage helps to combat oxidative stress in the body. Additionally, some cultures use the plant material to help manage certain types of skin irritations.

According to a study published by "Chinese journal of natural medicines", the leaf extracts of Amaranthus tricolor are used as part of a polyherbal formulation to evaluate antiulcer activity. This formulation, which includes the leaf extracts, was administered at a dosage of 150 mg·kg(-1), p.o. in rats. The study tested this mixture against 3 different models of gastric ulcers, specifically ethanol-induced, indomethacin-induced, and ischemia reperfusion-induced models. The results showed significant protection in all 3 experimental animal models of gastric ulcers when compared to the control group. These findings suggest that the gastroprotective activity of the formulation containing the leaf extracts of Amaranthus tricolor may be mediated by antioxidant activity.

What traditional systems uses this plant?

This plant, Amaranthus tricolor, has been utilized in traditional Ayurvedic and Siddha medicine systems to treat various ailments such as digestive issues and skin conditions. In the Ayurvedic tradition, its nutritional properties and specific therapeutic applications are leveraged to balance bodily humors. Similarly, the Siddha system incorporates the plant into holistic healing practices to promote overall wellness and vitality. Historical records indicate that these ancient medical practices relied on the plant's unique biochemical components for medicinal purposes. Beyond its medicinal value, the plant has also served as a functional dietary staple in many regional cultures.

According to a study published by "Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie", Amaranthus tricolor has been reported to possess many benefits and medicinal properties and used as a part of traditional medicine in Ayurveda and Siddha. In the study, rats were administered ISO subcutaneously at 50 mg/kg twice a week and were treated with ethanolic extracts of A. tricolor. This A. tricolor treatment prevented the rise of malondialdehyde, nitric oxide, and advanced protein oxidation product. The treatment also lowered elevated activities of AST, ALT, and CK-MB enzymes. Furthermore, A. tricolor treatment normalized increased uric acid and creatinine levels in ISO administered ovariectomized rats. The investigation suggests that A. tricolor treatment may protect against ISO administered myocardial infarction by preventing inflammation, oxidative stress, and fibrosis.

What are the pharmacological activities of Amaranthus tricolor?

This plant has anti-inflammatory, antihyperglycaemic, antimicrobial, antioxidant, and antiulcer pharmacological activities. Its rich concentration of phytochemicals allows it to neutralize free radicals and reduce oxidative stress within biological systems. These bioactive compounds also help in regulating blood glucose levels and inhibiting the growth of various pathogenic microorganisms. Furthermore, the plant extracts demonstrate a capacity to suppress inflammatory responses and protect the gastric mucosa from ulcer formation. Such diverse medicinal properties highlight its potential for developing new therapeutic agents.

According to a study published by "Molecules (Basel, Switzerland)", Amaranthus tricolor possesses medicinal properties that offer a neuroprotective effect against toxicity caused by advanced glycation end-products (AGEs). Preincubation of SH-SY5Y cells with petroleum ether, dichloromethane, or methanol extracts of A. tricolor dose-dependently attenuated the neuron toxicity induced by AGEs treatment. Furthermore, the extracts of A. tricolor significantly downregulated the gene expression of the pro-inflammatory cytokines TNF-α, IL-1, and IL-6 in AGEs-induced cells. These results indicate that A. tricolor has anti-inflammatory activity by reducing the expression of these specific cytokine genes. This suggests that the plant may be useful for treating chronic inflammation associated with neurodegenerative disorders.

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

  • anti-inflammatory
  • antihyperglycaemic

What medicinal compounds this plant contains?

This plant contains the medicinal compounds Atr-AMP1, Atr-DEF1, Atr-LTP1, Atr-SN1, and various types of defensin. These specific proteins play a crucial role in the plant's innate immune system by providing defense against pathogens. The Atr-AMP1 and Atr-DEF1 proteins function as antimicrobial peptides that disrupt the membranes of invading microorganisms. Additionally, Atr-LTP1 and Atr-SN1 contribute to structural stability and biological signaling within the plant tissue. Together, these defensin molecules form a complex chemical arsenal used to combat fungal and bacterial infections.

According to a study published by "Journal of natural products", the medicinal plant Amaranthus tricolor contains a novel 1.7 kDa antimicrobial peptide named Atr-AMP1. This positively charged proline-rich peptide exists in a heterogeneous population of multiple peptidofoorms. The peptide possesses several post-translational modifications, including a disulfide bond, methionine oxidation, and proline hydroxylation. Atr-AMP1 demonstrates strong activity against Escherichia coli ATCC 25922 and activity against Staphylococcus aureus LAC. These findings show the peptide is active against both a Gram-negative and a Gram-positive bacterial species.

What health conditions is this plant used for?

This plant is used for managing anaemia, diabetes, hyperglycaemia, postprandial blood glucose levels, and postprandial glycemic excursion. Its nutrient-dense profile provides essential minerals that help improve red blood cell production in patients suffering from anaemia. The bioactive compounds within the leaves assist in regulating blood sugar to combat the effects of diabetes. Specifically, it helps mitigate hyperglycaemia by stabilizing glucose fluctuations. Consumption of the plant can also effectively reduce postprandial blood glucose levels after meals. This regulation ultimately minimizes the postprandial glycemic excursion to maintain metabolic stability.

According to a study published by "African journal of traditional, complementary, and alternative medicines : AJTCAM", folk medicinal practitioners of Bangladesh use Amaranthus tricolor whole plants for the treatment of pain, anaemia, dysentery, skin diseases, diabetes, and as a blood purifier. The study evaluated antihyperglycaemic activity where the maximum effect was shown at 400 mg extract per kg body weight, which was comparable to the standard drug glibenclamide at 10 mg/kg body weight. In antinociceptive activity tests, the extract demonstrated a dose-dependent reduction in writhes at a maximum dose of 400 mg extract per kg body weight. This maximum dose compared favourably with the standard drug aspirin at 200 mg per kg body weight. These results validate the medicinal use of the plant for the reduction of blood sugar in diabetic patients and the alleviation of pain.
