The liver is not only involved in metabolism and detoxification, but also participate in innate immune function and thus exposed to frequent target Thus, they are the frequent target of physical injury. Interestingly, liver has the unique ability to regenerate and completely recoup from most acute, non-iterative situation. However, multiple conditions, including viral hepatitis, non-alcoholic fatty liver disease, long term alcohol abuse and chronic use of medications can cause persistent injury in which regenerative capacity eventually becomes dysfunctional resulting in hepatic scaring and cirrhosis. Despite the recent therapeutic advances and significant development of modern medicine, hepatic diseases remain a health problem worldwide. Thus, the search for the new therapeutic agents to treat liver disease is still in demand. Many synthetic drugs have been demonstrated to be strong radical scavengers, but they are also carcinogenic and cause liver damage. Present day various hepatic problems are encountered with number of synthetic and plant based drugs. Nexavar (sorafenib) is a chemotherapeutic medication used to treat advanced renal cell carcinoma associated with several side effects. There are a few effective varieties of herbal preparation like Liv-52, silymarin and Stronger neomin phages (SNMC) against hepatic complications. Plants are the huge repository of bioactive secondary metabolites viz; phenol, flavonoid, alkaloid etc. In this review we will try to present exclusive study on phenolics with its mode of action mitigating liver associated complications. And also its future prospects as new drug lead.

In spite of the progress in treatment strategies, cancer remains a major cause of death worldwide. Therefore, the main challenge should be the early diagnosis of cancer and the design of an optimal therapeutic strategy to increase the patient’s life expectancy as well as the continuation of the search for increasingly active and selective molecules for the treatment of different forms of cancer. In the recent decades, research in the field of natural compounds has increasingly shifted towards advanced and molecular level understandings, thus leading to the development of potent anti-cancer agents. Among them is the diterpene lactone andrographolide, isolated from Andrographis paniculata (Burm.f.) Wall. ex Nees that showed shows a plethora of biological activities, including not only anti-cancer activity, but also anti-inflammatory, anti-viral, anti-bacterial, neuroprotective, hepatoprotective, hypoglycemic, and immunomodulatory properties. Andrographolide has been shown to act as an anti-tumor drug by affecting specific molecular targets that play a part in the development and progression of several cancer types including breast, lung, colon, renal, and cervical cancer, as well as leukemia and hepatocarcinoma. This review comprehensively and systematically summarized the current research on the potential anti-cancer properties of andrographolide highlighting its mechanisms of action, pharmacokinetics, and potential side effects and discussing the future perspectives, challenges, and limitations of use.

Aging is a complex process that involves many physiological mechanisms that gradually impair normal cellular and tissue function and make us more susceptible to diseases and death. It is influenced by intrinsic factors like cellular function and extrinsic factors like pollution and UV radiation. Recent scientific studies show that traditional plant-based foods and supplements can help mitigate the effects of aging. Nutraceuticals, which are dietary supplements with medicinal properties, have gained attention for their ability to prevent chronic and age-related diseases. Antioxidants like flavonoids, carotenoids, ascorbic acid, terpenes, tannins, saponins, alkaloids, minerals, etc. found in plants are key to managing oxidative stress, which is a major cause of aging. Well-known plant-based supplements from Bacopa monnieri, Curcuma longa, Emblica officinalis, Ginkgo biloba, Glycyrrhiza glabra, and Panax ginseng have been found to possess medicinal properties. These supplements have been shown to improve cognitive function, reduce oxidative stress, improve overall health, and potentially extend life and enhance the excellence of life. The obtained benefits from these plant species are due to the presence of their bioactive secondary metabolites, such as bacosides in Bacopa monnieri, curcumin in Curcuma longa, ginsenosides in Panax ginseng, and many more. These compounds not only protect against free radical damage but also modulate key biological pathways of aging. Also, traditional fermented foods (tempeh and kimchi), which are rich in probiotics and bioactive compounds, support gut health, boost immune function, and have anti-aging properties. The molecular mechanisms behind these benefits are the activation of nutrient-sensing pathways like AMPK, SIRT/NAD+, and mTOR, which are important for cellular homeostasis and longevity. This review shows the potential of traditional plant-based foods and dietary supplements for healthy aging, and more studies are needed to prove their efficacy and safety in humans. Incorporating these natural products into our diet may be a practical and effective way to counteract the effects of aging and overall well-being. The foremost goal of this review is to emphasize the importance of supporting the body’s antioxidant system by consuming the right balance of natural ingredients in the diet.

Our health-care system would be incomplete without the use of medicinal herbs. In the days before modern medicine, several communities created medical knowledge systems known as “traditional medicine,” “indigenous medicine,” or “folk medicine.” The medicinal properties of plants and plant-based products are widely accepted. There are a variety of medical approaches available across the world, including allopathic, homoeopathic, Ayurvedic, and Chinese. The developed communities each have their own Materia Medica, which compiles thorough data on many plants used as medicines. According to current estimations from the field of botany, there are somewhere between 2,50,000 and 3,50,000 distinct plant species in existence. It is estimated that 35,000 unique species are used to cure a wide range of ailments in diverse places throughout the world. Based on general popularity among all ages, phytopharmaceuticals are an integral part of worldwide business and the global economy. According to a globe news wire study, the global herbal medicine market is estimated to be 550 billion dollars by 2030, up from 83 billion dollars in 2019. China and India lead the global herb market. China exports 120,000 tonnes of herbal remedies annually, followed by India with 32,000 tonnes. Europe is the world’s largest importer of medicinal plants (MP), taking in over 400,000 tonnes annually to fulfill local demand. In this review, we have discussed about the MP and their economic importance in global market.

The major cause of death around the world is cardiovascular disease, while cancer ranks second. Lung cancer stands out as a major cause of concern because it accounts for 12% of all cancer cases and is the leading cause of cancer-related death. Since prehistoric times, humans have relied on plants as a reliable resource for all three of these essentials: food, livestock, and healthcare. When it comes to treating human illness, plants have been relied on extensively. Researchers are becoming increasingly intrigued by the prospect of deciphering plant chemistry. The Alliaceae plant family has yielded many novel phytochemicals. To identify a potent phytocompound against lung cancer from the plant Allium tuberosum Rottler ex Spreng, gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) were performed. Before that, total phenolic content (TPC), total flavonoid content (TFC), and DDPH free radicals scavenging activity were determined in order to select the best plant extract. Four targets for non-small cell lung cancer (NSCLC) were retrieved in mutated form by literature mining to carry out this work. EGFR and B-Raf were selected as cell proliferating proteins and K-Ras and PI3K were selected as antiapoptotic proteins. Molecular docking was performed against these targets with the 94 phytocompounds present in Allium tuberosum, which were identified by GC-MS and LC-MS. Chemical absorption, distribution, metabolism, excretion, and toxicity (ADMET) profiling was also conducted with the nine best-screened compounds. Americine, an alkaloid from this plant, showed inhibitory activity against all four selected targets and was bound more strongly than their respective positive controls in docking studies amongst all other phytocompounds. The ADMET study also confirmed the drug-like candidature of the compound. This study reveals the alternative therapeutic potential of americine against NSCLC by promoting apoptosis and inhibiting cell proliferation.
