" Curcumin has a
long established safety record. For example, according to JECFA
(The Joint United Nations and World Health Organization Expert
Committee on Food Additives) and EFSA (European Food Safety
Authority) reports, the Allowable Daily Intake (ADI) value of
curcumin is 0–3 mg/kg body weight. Several trials on healthy
subjects have supported the safety and efficacy of curcumin." - Curcumin, an active component of turmeric (Curcuma longa), and
its effects on health | Critical Reviews in Food Science
and Nutrition
"Curcumin has been one of the most studied herbal remedies,
attracting strong pharmaceutical attention due to its diverse
biological activities. Curcumin is one of the most studied
phytochemicals used as anticancer molecules. This polyphenol has
been used in traditional medicine in Asia since ancient times
and it has been shown to have extensive cytotoxic effects
against cancer cells. In addition, curcumin has also shown
beneficial and protective functions in acute myocardial
infarction and cardiovascular diseases, chronic atherosclerosis,
neurodegenerative diseases and autoimmune diseases. Interest in
curcumin has gradually increased after several studies
demonstrated its chemotherapeutic and chemopreventive effects."

International Journal of Molecular Sciences | 2023
"Curcumin is the most important chemical component of
turmeric, which can exert antioxidant, anti-inflammatory,
anti-angiogenic and anti-tumor pharmacological effects without
significant adverse effects. Studies have shown that curcumin
and curcuminoids in turmeric could provide good protection
against many chronic diseases in the body by inhibiting
inflammatory responses, lowering blood lipids, and improving
blood sugar. Curcumin in turmeric can effectively inhibit
inflammatory reactions and reduce symptoms such as pain and
swelling. In recent years, it was found that curcumin could
alleviate some symptoms in some autoimmune diseases such as
rheumatoid arthritis and inflammatory bowel disease" -
Frontiers in Immunology | 2023
"For thousands of years, turmeric has been used to treat
common colds, fevers, stomachaches, liver diseases, open wounds,
skin diseases, and chronic inflammations. After epidemiological
studies, turmeric may have the ability to lower cancer incidence
rates by 10-50% among those who regularly consume the spice.
Considered pharmacologically safe, curcumin possesses various
effects, including antioxidant, anti-inflammatory, and
anti-septic properties, and also modifies its influence on the
expression of genes involved in cytotoxicity, angiogenesis,
metastasis, and drug resistance. Curcumin mediates its promising
activities by regulating several key molecular targets." -
International Journal of Biological Sciences | 2023
"Curcumin is characterized by many desirable properties. It
has anti-inflammatory, antioxidant, and anticancer properties,
among others. Furthermore, importantly, it is safe and rarely
causes adverse symptoms. For this reason, it is used to treat or
support the treatment of many diseases, e.g., cardiovascular
diseases, inflammatory bowel diseases, breast, stomach,
pancreatic and lung tumors, dermatoses, allergic asthma, and
liver diseases." -
International Journal of Environmental Research and Public
Health | 2023
"According to the results of preclinical and clinical studies
conducted in vitro and in vivo, curcumin may be helpful in the
prevention and treatment of many diseases, including
cardiovascular diseases, diabetes mellitus, obesity, allergy,
asthma, inflammatory diseases, and neurodegenerative disorders,
e.g., Alzheimer’s, Parkinson’s, multiple sclerosis, and
Huntington’s disease by affecting different molecular targets.
Over the few current decades, considerable studies have been
conducted on curcumin due to its beneficial health properties,
including potent antioxidant properties, antimicrobial,
anti-inflammation, anticancer effects, cardio-protectiveness,
and hypoglycemic action. Compared to other medications, curcumin
is viewed as a very cost-effective and safe natural substance
that can be used to prevent and treat many disorders." -
Impacts of turmeric and its principal bioactive curcumin on
human health: A comprehensive review | 2023
"Research suggests that curcumin can help in the management of
oxidative and inflammatory conditions, metabolic syndrome,
arthritis, anxiety,,and hyperlipidemia. It may also help in the
management of exercise-induced inflammation and muscle soreness,
thus enhancing recovery and subsequent performance in active
people. In addition, a relatively low dose can provide health
benefits for people that do not have diagnosed health
conditions." -

"One of the most commonly used herbal supplements is
curcumin, which has been extensively studied in cancer
prevention and treatment. In fact, a plethora of preclinical
studies have demonstrated the anti-cancer properties of curcumin
as well as its role as a chemosensitizer agent." -

"Curcumin, the key bioactive phytochemical present in
turmeric (Curcuma longa L.), is the most studied
natural compound in cancer. Preclinical studies (in vitro
and in vitro) and clinical trials have demonstrated
curcumin's effectiveness as an anti-inflammatory agent. The
existing evidence supports that curcumin inhibits the
proliferation of many types of cancer cells related to the
effect on different types of cancers, such as chronic myeloid
leukemia, multiple myeloma, prostate, colorectal and pancreatic
cancer as well as cancer therapy-related complications,
including oral mucositis and radiation dermatitis." -

"Curcumin, a multi-targeted compound, has traditionally been
used as a dietary spice and a medicinal herb in Asian countries
for a variety of pathologies due to its anti-inflammatory
properties, and antioxidant properties. Moreover, curcumin
possesses antibacterial, antiviral, antifungal, anti-arthritic,
hepatoprotective, anti-thrombotic, cardio-protective,
hypoglycemic, anti-allergic, wound-healing, and chemo-preventive
and anticancer properties. Curcumin’s anti-inflammatory and
antioxidant effects, among others, form the basis of curcumin’s
critical neuroprotective effects in a variety of neurological
diseases affecting both the central and peripheral nervous
systems. Several molecular targets of curcumin have been
identified based on extensive evidence from in vitro and in vivo
studies." -
