Cancer is a complex disease caused by genetic mutations and external factors like radiation and lifestyle choices. Traditional treatments, including chemotherapy and radiation, often cause severe side effects, prompting interest in alternative therapies. Herbal remedies, rich in phytochemicals, have shown promise in cancer prevention and treatment by targeting tumor growth, inducing apoptosis, and inhibiting angiogenesis and metastasis. This review article aims to explore and analyze the potential of herbal remedies in cancer treatment, focusing on their mechanisms of action, including apoptosis induction, inhibition of angiogenesis, and modulation of molecular pathways.
This review examines key phytochemicals curcumin, naringenin, capsaicin, and resveratrol for their anticancer properties. Relevant studies were analyzed to assess their mechanisms of action, such as apoptosis induction, inhibition of molecular pathways like COX-2 and 5-LOX, and protective effects on healthy cells. A literature search was conducted using databases such as PubMed, Scopus, and Web of Science. Keywords included “phytochemicals,” “herbal,” “curcumin,” “naringenin,” “capsaicin,” “resveratrol,” “herbal remedies,” and “cancer therapy.” Studies published in peer reviewed journals over the past 30 years were selected. The quality of the literature was assessed based on study design, sample size, reproducibility, and relevance to cancer treatment.
The findings highlight that these phytochemicals exert significant anti-cancer effects by inducing cell cycle arrest and apoptosis while inhibiting angiogenesis and metastasis. For example, curcumin and resveratrol inhibit cancer progression by targeting key molecular pathways. Additionally, herbal remedies protect healthy cells from damage often caused by chemotherapy and radiation, making them an attractive alternative or complementary option for treatment.
These phytochemicals demonstrated significant therapeutic potential through multi-targeted actions, such as apoptosis induction, angiogenesis inhibition, and protection of healthy cells. Their ability to complement conventional therapies, highlights the relevance of integrating herbal remedies into cancer management strategies.
Herbal remedies, with their potent phytochemicals, offer a promising alternative to cancer therapy, providing protective effects to normal cells while targeting cancerous ones. Their lower toxicity compared to conventional treatments suggests they could play a crucial role in future cancer therapies. However, further clinical research is needed to establish optimal dosages and treatment protocols for effective integration into cancer care.
