The Role of Herbal Medicine in Modern Healthcare: A Comprehensive Review

Herbal medicine, also known as phytomedicine, is a powerful approach that uses plant-based remedies to treat diseases, with historical significance, current popularity, and promising future healthcare prospects (Ghosh et al., 2023). Plants that contain phytochemicals such as flavonoids, alkaloids, and saponins are used in herbal therapy to treat a variety of illnesses. Using herbal extracts in lipid molecular complexes provides novel drug delivery strategies with improved solubility, bioavailability, and side-effect prevention (Ahmed et al., 2023).

Herbal medicine complements conventional treatments by using plants and other natural resources to boost immunity and treat illnesses. It has strong therapeutic potential, helping patients with weakened immune systems. It can also improve immunotherapies and stop the progression of sickness (Ferreira de Oliveira et al., 2022). With ancient roots, herbal medicine is utilised extensively around the world for healing purposes, food preparation, and spiritual practices. Plant bioactive components are essential to its effectiveness, necessitating study and legislative measures (Izah et al., 2023).

Herbal remedies are vital to contemporary medicine because they provide affordable, socially and culturally acceptable, and low-risk therapies for infections caused by bacteria, viruses, and protozoa. Research has demonstrated the efficacy of Indian medicinal plants in the treatment of COVID-19, viral disorders, gastrointestinal tract infections, and wound and skin infections. These medications work in concert with one another and are reasonably priced. For the treatment of COVID-19, homoeopathic medications and herbal extracts are also utilised (Chaughule & Barve, 2023).

When it comes to developing new therapeutic agents, natural products are essential to the revitalisation of the healthcare industry. Chronic inflammation, cancer, and antibiotic resistance are only a few of the disorders that can be effectively treated thanks to their distinct chemical diversity and biological activity (Sathishkumar, 2024). Herbal medicine offers safe, efficient, and bioactive treatments by bridging the gap between conventional wisdom and contemporary science. Through holistic methods, it enhances global well-being and complements contemporary treatment (Balkrishna et al., 2024). Despite physician reluctance, botanicals have a role in modern healthcare by addressing rising demand, emphasising safety and usage, and requiring healthcare providers to understand interactions with conventional drugs (Chen See & Baum, 2023).

The Ayurvedic, Siddha, and Unani medical systems integrate contemporary and ancient medicine through the use of medicinal plants that have antibacterial, anticancer, and neuroprotective qualities. These ancient methods tackle underlying causes rather than symptoms, placing a higher priority on long-term health (Shamim et al., 2024). In dentistry, herbal remedies, including those with biological effects, are frequently utilised for endodontic treatments because of their antibacterial qualities and capacity to avoid adverse effects, which allows them to safely replace commercial agents (Balagopal et al., 2023).

Saraca indica is a potent antibacterial and anti-inflammatory agent, aiding in urinary tract cleanliness and in the reduction of pain and inflammation, and has various pharmacological effects (Nayab et al., 2023). It has been discovered that basil, a herb with possible antihypertensive properties, can cure cardiovascular disorders with fewer adverse effects (Palshikar et al., 2024). The common plant Clinacanthus nutans is becoming increasingly well known for its medicinal properties, its ability to block UV rays, its ability to prevent cancer, and its use in personal care products (Kumar et al., 2024). Indian borage, holy basil, peppermint, fenugreek, and Indian acalypha are five common herbs used for medical purposes. Many therapeutic benefits, including antibacterial, anti-inflammatory, antioxidant, and anticancer effects, are associated with these plants. With no negative side effects, they can be employed in medicine (Jancy & Inbathamizh, 2022). The pharmacological effects of herbal medicines on the course of autosomal dominant polycystic kidney disease (ADPKD) and their mechanisms in both in vitro and in vivo models have been reviewed in recent research. The review draws attention to the possible advantages of triptolide, curcumin, and ginkgolide B in preventing the formation of renal cysts (Shao et al., 2021).

Five herbal plants, namely Indian borage, holy basil, peppermint, fenugreek, and acalypha, are the subject of a recent study that explores their phytochemistry, biological characteristics, traditional usage, and medical applications. Antioxidant, antibacterial, anti-inflammatory, and anticancer qualities are only a few of these plants’ many therapeutic qualities. Their usage in medicine is safe and effective (Jancy & Inbathamizh, 2022). A review of recent studies examines the possible therapeutic uses of herbal remedies for osteoarthritis, such as ginger, devil’s claw, and epimedium. It draws attention to the chondrogenic, analgesic, and anti-inflammatory properties of these medications. To completely understand how well these components work to manage arthritic symptoms, more study is required on their mechanisms, safety, and active constituents (Anvari et al., 2020). Through a variety of pathways influencing lipid metabolism and inflammation, herbal therapy has demonstrated substantial advantages in the treatment of non-alcoholic fatty liver disease (NAFLD), including improved steatosis and inflammation. Clinical studies support these advantages and show how well herbal medication works for treating NAFLD patients (Xu et al., 2020).

Herbal remedies used in traditional Iranian medicine, such as camel thorn, lemon balm, watercress, borage, ginger, cinnamon, psyllium, rosemary, chicory, and valerian, can be poisonous at excessive dosages and induce liver damage and changes in enzyme levels. These plants contain a variety of poisons that can impact different human organs. These toxins include alkaloids, glycosides, organic acids, resins, resinoids, and mineral compounds (Ebadollahi-Natanz & Arab-Rahmatipour, 2023). Concerns regarding adulteration and contamination are raised by the growing usage of phytopharmaceuticals and herbal remedies in both developed and developing nations. Lax quality control and ineffective monitoring systems can lead to contamination with heavy metals and pesticides, which raises toxicological issues and makes it difficult for toxicologists to evaluate herbal medicines (Cheng et al., 2023).

Herbal supplements have the potential to cause negative responses by changing medication concentrations, influencing metabolism, and interfering with testing. St John’s wort is a popular example. These interactions can be identified using therapeutic drug monitoring. Moreover, herbal supplements can change a patient’s reaction to medication treatments and the blood concentrations of medications that are administered concurrently (Likhodii et al., 2024). The causes and clinical implications of interactions between herbs and drugs are covered in a recent review. Given that herb–drug interactions can have negative consequences and reduce the advantages of medication, the review emphasises the need for further clinical evidence to make well-informed judgements about patient safety. The need to raise awareness of possible interactions between prescription medications and herbal supplements is emphasised in the research (Rasheed et al., 2023).

New literature examines the holistic character of traditional and complementary medicine (T&CM), highlighting the significance of herbal medicine and the necessity of taking into account the opinions of many stakeholders in order to integrate T&CM effectively. It offers methods for promoting acceptance and incorporating herbal therapy into conventional medical practices (Salau et al., 2024). Integrating contemporary, complementary, and alternative medicine can boost overall health outcomes, lower expenses, and improve patient outcomes (Gupta, 2023). The benefits of combining herbal therapy with traditional medicines are discussed in another study, with an emphasis on how doing so may lessen side effects and enhance therapeutic results. It emphasises the value of a comprehensive strategy in healthcare, with a focus on the advantages for professionals, patients, and clients. The significance of involving clients in pet healing for success is also emphasised in the study (Perdrizet, 2023). Resolving issues with healthcare delivery and enhancing health outcomes are possible when conventional and contemporary medicine are combined. Nonetheless, there are obstacles such as disparities in fundamental methodologies, distinctions in epistemology, and all-encompassing health policies. Cross-referrals between traditional and mainstream medicine, better communication, and more awareness are necessary for successful integration (Srikanth, 2021).

Research advancements in herbal medicine offer significant potential to enhance our understanding and use of medicinal plants for therapeutic purposes. A key area of focus is the integration of biotechnology, including genetic engineering techniques like CRISPR/Cas9, to increase the production of specific bioactive compounds in medicinal plants, thereby boosting the availability of rare but therapeutically valuable phytochemicals. Metabolic engineering further enables the modification of plant pathways to synthesise novel compounds or increase the yield of existing ones, potentially leading to the development of new drugs and more potent herbal remedies. Additionally, omics technologies, such as genomics, transcriptomics, and metabolomics, are being utilised to uncover genetic, transcriptomic, and metabolic profiles of medicinal plants, facilitating the discovery of novel bioactive compounds and paving the way for personalised treatments based on human genetic variations. Sustainable production practices are being developed through green chemistry approaches and nanotechnology-based delivery systems, which aim to minimise environmental impact and enhance the bioavailability of herbal compounds. Moreover, ethnopharmacological research focuses on documenting traditional knowledge from indigenous and local communities, preserving ethnobotanical information, and guiding new drug discoveries. Community-based participatory research ensures that studies are culturally relevant and benefits are shared equitably. Regulatory and standardisation efforts are crucial for ensuring the quality, safety, and efficacy of herbal medicines, and they involve developing standardised protocols for plant cultivation, harvesting, and processing. Furthermore, sustainable practices in the cultivation and conservation of medicinal plants, both in situ and ex situ, are essential to preserve biodiversity and reduce the strain on wild populations. These innovative approaches underscore the importance of a multidisciplinary strategy that integrates traditional knowledge with modern scientific advancements, positioning herbal medicine as a vital component of future healthcare systems.
