Introduction
Cancer is a global health problem because of its high prevalence and poor prognosis.It can affect any part of the body and spread one part to other organs.Widespread metastases are the most imperative reason of death in cancer [1].The Cancer registry specifies 18.1 million new cases and 10 million global deaths due to cancer in 2020.Although the most common cancers are breast, lung, colorectal and prostate, contributing 12.5%, 12.2%,10.7%and 7.8% respectively to the total number of new cases diagnosed in 2020 [2].Moreover, in India, 1.3 million new cancer cases and 0.85 million deaths were reported [3].The burden of cancer incidence and mortality is rapidly growing worldwide [4].
Cancer occurs due to over expression of oncogenes or damage in DNA.Conversely, oxidative stress or reactive oxygen species (ROS) play a considerable role in key cellular pathways of DNA damage, mutagenesis and apoptosis.Besides genetic injury, habitual use of tobacco, alcohol dependence, inadequate diet, physical apathy, radiation, chemical and environmental pollutants are the major threats considered for any type of cancer [5].The International Agency for Research on Cancer (IARC) has already identified more than 150 chemicals, drugs, foods, airborne particles, ionizing radiation and other consumer products as potential carcinogens [6].
There are four types of therapeutic modalities in cancer depending upon the nature, progression of disease conditions and possibilities of recovery, viz.surgery, chemotherapy, radiation therapy and palliative care.In the early 1900s, the term "chemotherapy" was first introduced by German chemist Paul Ehrlich to treat specific infective conditions like cancer with chemicals.After several attempts, methotrexate (1948), chlorambucil (1957), cyclophosphamide (1959), 5-fluorouracil (1970), Doxorubicin (1974) and Cisplatin (1978) were developed for the treatment of cancers [7].Cytotoxic chemotherapeutics target directly to DNA; while the target chemotherapeutics aim at the abnormal protein expression inside the malignant cells [8].At this time, although chemotherapy is the most powerful weapon to treat deadly cancers, causes widespread cytotoxicity of healthy cells and causes severe side effects, such as nausea, emesis, anorexia, diarrhoea, skin damage and hair loss.To overcome these unwanted side effects, searching for novel and safe chemotherapeutics for cancer is crucial.Consequently, alternative medicine may provide a safe chemotherapeutic to treat cancer without undesirable side effects.

5-Fluorouracil Cisplatin Paclitaxel
Figure 1: Anticancer medicines The anticancer properties of plants have been recognized from ancient times.The innovation of the application of the plant alkaloids (Vincristine and Vinblastine from Vinca rosea) for both leukaemia and Hodgkin's disease has been considered a major breakthrough in the research of chemotherapeutics (1963).From that time to till now, numerous chemotherapeutics have been isolated, identified or developed from natural resources.Paclitaxel (Texol) was obtained from the bark of Taxus baccata (2002), while colchicine alkaloid was first isolated from the corn of Colchicum autumnale (2009) and has exhibited clinical significance against different cancers such as ovarian, breast, prostate and lung cancer [9,10].There are reports that several natural supplements, including single or mixed herbal extracts and pure compounds are able to reduce the harmful side effects of chemotherapy and can improve the quality of life (QoL) of cancer patients [11][12][13].

Materials and Methods
A bibliographic search of PUBMED, MEDLINE, Academic Google, and other relevant websites (2010-2022) was performed for the present study.Indian medicinal plants employed in the Indian herbal formulation (Body Revival) have been the top search terms.Following the rigorous reading of the titles and abstracts used in the original search, only fully published papers were selected to take part in this review.

Results and Discussion
Herbal extracts consisting of multiple herbs for the management of cancer have been used in Ayurveda, Indian System of Medicine, since immortal time.These formulations are reported to work on multiple biochemical pathways simultaneously [17].It is observed that mixed herbal formulations are more effective than any single herb due to their similar cumulative actions.On this concept Body Revival (Health Reactive, Rajasthan, India), a formulated herbal liquid suspension has been developed based on immunotherapy to treat cancers as mentioned in ancient Ayurvedic texts.The nine natural ingredients of Body Revival are selected from the traditional medicines as mentioned in Ayurvedic Pharmacopoeia of India [18].The composition of Body Revival suspension (5 ml) contained pure extract of Aegle marmelos fruit pulp (150 mg), Acorus calamus rhizome (175 mg), Withania somnifera root (325 mg), Blumea lacera fruit (115 mg), Rumex vesicarius whole plant (240 mg), Rubia cordifolia root (200 mg), Cucumis melo seed (200 mg), Symplocos racemosa stem bark (95 mg) and honey (Q.s).Earlier preclinical studies reported, it has potent antiinflammatory, immunomodulatory, chemo preventive and antithrombotic actions.Body Revival contained polyphenolic compounds and exhibited beneficial action on myelosuppression and cardiac ischemia [19][20][21].It has been reported that Body Revival therapy unquestionably better the health condition in general and mental disabilities and illness due to weak immune circumstances by modulating signalling pathways or/and cellular functions.In due course, it is helpful to fight infections from environmental pathogens or chemicals that suppress physical immunity [21].
Body Revival is used to improve the body's defence mechanism, repair damaged tissues, flush out harmful metabolites through excretion and rejuvenate healthy cells and helpful to improve quality of life and enhance longevity during palliative care in cancer patients in the last 25 years.In this juncture, we are trying to focus on the importance and the perspective of the use of Body Revival in cancers with comprehensive evidence and justification.The main part of this review is based on underlying plausible mechanistic analysis of its individual phytoconstituents as chemotherapeutics/or adjuncts and their synergistic impacts on the management of cancer.

Anticancer activities of phytochemicals present in the ingredients of Body Revival
The anticancer properties of the ingredients present in Body Revival are pure aqueous extracts of Aegle marmelos fruit pulp, Acorus calamus rhizome, Withania somnifera root, Blumea lacera fruit, Rumex vesicarius whole plant, Rubia cordifolia root, Cucumis melo seed, Symplocos racemosa stem bark and honey.

Withania somnifera
Withania somnifera familiar as "ashwagandha" or "winter cherry" or "Indian ginseng" is belongs to the family of Solanaceae.It exhibits antioxidant, anti-inflammatory, anti-stress, immunomodulatory, adaptogenic, chemo preventive effects, anticancer activity.The rhizome/root contains two main bioactive anticancer components, Withanolide and Withaferin A [36].W. somnifera is a promising therapeutic agent for a broad range of cancers.It showed cytotoxicity against four human cancer cell lines such as prostrate DU-145, colon HCT-15, lung A-549 and neuroblastoma IMR-32 [37].Several studies demonstrated that Withaferin A (WA) has the potential to restrict the genesis and proliferation of cancer cells via controlling the non-genetic influences on gene expression [38,39].It also reduced the side effects of some cancer chemotherapeutic agents, viz.cyclophosphamide and paclitaxel without interfering with the cancer-reducing actions of the drugs [40].Recently, it has been reported WA inhibited cell cycle, angiogenesis, proteasomes and tumor growth in the prostate [41].Nagy and his co-workers (2020) reported that WA activates TRIM16 (tripartile motif 16) expression, which acts as tumor suppression in melanoma [42].In molecular docking studies, Withanolide, WA and Withanone showed the best binding affinity against Protein kinase C and (ii) NF-KB.Furthermore, enzyme ligand binding affinity have also been noted against Tyrosineprotein kinase JAK1, Mitogen-activated protein kinase P38, Glutathione Reductase and Glutathione S-Transferases [43,44].Molecular docking study also provides evidence that Withanolide, Withaferin A and Withanone robustly attach to the macromolecules to restrain escalation of cancer cells, as a promising anticancer medicine.

Rumex vesicarius
Rumex vesicarius also known as "amlabet" or "bladder dock" is belongs to the family of Polygonaceae.It is used in the treatment of tumors, liver diseases, cardiovascular disease, asthma, bronchitis and nausea [50].It possessed a promising anticancer potential against MCF-7 and WRL68 cell lines and HCC induced hepatic carcinoma model.It showed potent antiangiogenic and antiproliferative activities [51,52].

Cucumis melo
Cucumis melo or "madhuphala" or "muskmelon" is belongs to the family of Cucurbitaceae.Cucurbitacin B (CuB) is a tetracyclictriterpenes present in Cucumis melo [60].The anticancer activity of CuB in human leukemia cells has been observed.It restrains STAT3 activation and the Raf/MEK/ERK pathway in K562 leukemic cells [61].It is also used as a liver protection medicine in curing hepatic lesions and liver cancer [60,62].CuB also inhibited multiple myeloma cells in the G2/M phase [63].Cucumis melo exhibited cytotoxicity against PC3, HCT116, HeLa, and Jurkat cell lines [64].

Symplocos racemosa
Symplocos racemosa or "Lodhra" is associated with the family of Symlocaceae.It has been extensively applied in traditional medicine for gastro-intestinal and liver problems, uterine complaints, menstrual disorders and solid tumors.It has several bioactive glycosides such as symplocomoside, symponoside, benzoyl salireposide, salireposide etc. [65,66].Symplocos racemosa bark showed cytotoxic action on Hep3B hepatocellular carcinoma cells [67].Raval and his coworkers (2009) evaluated the chloroform, butanol and methyl acetate bark extracts for their cytotoxicity assay against leukemia and cervical cancer cell lines.They reported that the butanol extract had the highest cytotoxicity activity against HeLa cell line [68].

Honey
Honey is composed of sugars, amino acids, proteins, enzymes, vitamins, flavonoids, phenolic acids and other compounds.Bioactive polyphenolic compounds such as kaempferol, quercetin, chrysin, luteolin, apigenin, naringenin etc are present in honey [69].Honey has potential apoptotic, antiproliferative and immunomodulatory activities [70].It antagonizes estrogenic activity, restricts cell proliferation, exaggerates apoptosis and reduces mitochondrial membrane potential in the two most widely used breast cancer cell lines, MCF-7 and MDA-MB-231 [71,72].It inhibits cell proliferation, suppresses angiogenesis, induces apoptosis, protects against mutagen-induced DNA damage in HepG2 liver cancer cells and HT 29 colorectal cancer [73].Honey contains other anticancer molecules such as methylglyoxal, which inactivates glyceraldehyde-3-phosphate dehydrogenase (GA3PD) and down regulates ATP production in cancer cells and thereby accelerating the death of cancer cells [74].Hence, honey is potentially helpful to resist cancer via controlling three key steps of carcinogenesis: initiation, proliferation and progression.

Therapeutic Application of Herbal Formulations in Cancer
Herbal formulations frequently composed with some primary herbs which are responsible for the target therapeutic actions and accessory herbs which have either synergetic actions to improve the therapeutic properties of primary herbs or nullifying the other effects related to disease.There are multiple scientific evidences and clinical trial reports of using herbal formulations on cancers.In this juncture, some marketed anticancer drugs are tabulated in the Table 2. Most of these formulations are now applied as a combination therapy with the conventional chemotherapy, radiotherapy or palliative care treatment to enhance the therapeutic advantages by reducing the side effects or complications.Anorexia, vomiting, constipation, diarrhoea, anaemia, headache, fatigue, pain, infection and hair loss are the common sign and symptoms of conventional therapy in cancers.A substantial number of meta-analysis and review of randomized control trials specifically informed that herbal medicines and formulations could improve the quality of life of cancer patients during conventional therapy and palliative care [87][88][89][90].Other than that life style modifications including food habits, exercise, meditation and Yoga can improve the quality of life of cancer patients, particularly during palliative care [91,92].

Conclusions
The burden of cancer in society can be lowered by early detection and to starting effective and specific treatment management of cancer.Most cancers have high possibility of curing if diagnosed early and preventing the spread of disease.Body Revival is a polyherbal medicine intended to use broad spectrum cancer patients.From literatures based on ancient knowledge and modern research, strongly admits that Body Revival is able to stimulate the immune system, protect DNA from injury, restores damaged DNA, lower oxidative impairment, anti-proliferation, cancer cell cycle arrest, initiation of apoptosis, suppression of angiogenesis and metastasis, chemo preventive or restore/protects normal cells from harmful effects of radiation.The goal-oriented programmed clinical approaches are highly desirable in future to conclude the effectiveness and nature of the anticancer drug of natural origin.
