Medicinal plants are essential to human health and have been used for ages because of
their therapeutic properties, economic value, and medicinal benefits. These plants
include a broad variety of species, including both herbs and trees, and they are all
significant in the medical sector because of their distinct qualities.
some examples of medicinal plants and information on the potential mechanisms of
action for the medicinal plants mentioned:
1.1Green tea (Camellia sinensis): Green tea includes a number of bioactive
chemicals, but epigallocatechin gallate (EGCG), a kind of polyphenol, is the one that
is frequently linked to the plant's possible health advantages. A plant pigment and
natural antioxidant, EGCG is a catechin that can be found in a variety of foods and
drinks. Many research works have looked into EGCG's possible anti-cancer effects. It
has been proposed that EGCG may work through a number of methods to prevent the
growth of lung cancer cells, such as:
1 .Antioxidant activity: EGCG has the ability to reduce oxidative stress and scavenge
free radicals, both of which are linked to the onset and spread of cancer [1].
2 .Anti-inflammatory effects: Research has demonstrated the anti-inflammatory
qualities of EGCG, and chronic inflammation has been linked to the development of
cancer. EGCG may aid in preventing the formation of cancer cells by lowering
inflammation [1].
3 .Apoptosis induction: EGCG has been found to promote apoptosis, which is
programmed cell death. By triggering apoptosis in cancer cells, EGCG may help
prevent their uncontrolled growth [2].
4 .Inhibition of angiogenesis: EGCG may inhibit the formation of new blood vessels
that supply tumors with nutrients and oxygen, thereby impeding their growth [2].
2.1 .Turmeric (Curcuma longa):
The active ingredient in turmeric that has been studied for its potential anti-cancer
effects is a compound called curcumin. Curcumin is a naturally occurring polyphenol
and the primary bioactive compound found in turmeric, which is derived from the
rhizome of the Curcuma longa plant. Curcumin has been extensively researched for
its potential anti-cancer properties, including its effects on lung and liver cancer cells.
Some of the ways in which curcumin may inhibit the growth and spread of cancer
cells include:
1 .Anti-inflammatory activity: Research has demonstrated the potent anti-
inflammatory qualities of curcumin. Curcumin may aid in inhibiting the growth of
cancer cells by lowering inflammation, which is linked to the onset and spread of
cancer [3
