Black Pepper

Black Pepper is the dried mature berry of Piper nigrum, a climbing, perennial shrub mostly found in hot, moist region of Southern India. Under cultivation pepper vines are trailed over support as columns, 5-6 mtr tall, 1-2 meter diameter. The climbing woody stems have swollen nods with clinging roots at each node, which helps in anchoring the vine to the support trees (standards). It has straight upward growing main stem and have lateral shoots from the axils of the leaves having shorter inter nodes without adventitious roots. In such branches the terminal buds get modified into an inflorescence (spike) and the auxiliary buds continue further growth.

The root system confined to 75-100 cm radius and depth. The inflorescence is a pendent spike, 3-15 cm long with 50-150 flowers. Flowers are minute, white pale yellow, arranged spirally on fleshy pedantries. The specie is naturally self-pollinated and pollen dispersal is aided by the presence of water droplets. Fruit is a single seeded drupe often called berry. It is spherical in shape, green in colour, changing to red on ripping.                                      


Pepper is considered originated in the hills of South Western Ghats of India. It is now grown in Indonesia, Malaysia, Sri Lanka, Thailand, China, Vietnam, Cambodia, Brazil, Mexico, and Guatemala apart from the country of origin. Pepper requires hot and humid climate and grows between 20 degree North and South latitudes, from sea level to up to 1500 meters above MSL. The crop tolerates temperatures between 10 degree and 40 degree C. A well-distributed annual rainfall of 125 to 200 cm is considered ideal for pepper.

Uses of Black Pepper:

Pepper is largely used by meat packers and in canning, pickling, baking, considering for its preservative value. It has the ability to correct the seasoning of dishes, therefore used as a final dash at the end of cooking to effectively adjust the flavour. It is an important component of culinary seasoning of universal use and is an essential ingredient of numerous commercial foodstuffs. It is also used as an ingredient in spice mixes. White pepper is used in products like mayonnaise where, black specks of black pepper is not liked. Other products in use are pepper oil, oleoresin, micro encapsulated pepper, green pepper in brine, dehydrated green pepper, frozen pepper etc. Black pepper is an essential ingredient in Indian system of medicine. Piperine, the pungent principle in pepper oleoresin helps to enhance bio-availability and therefore used in pharmaceuticals. They have been used as carminative, reducing stomach and intestinal gas and have been found to stimulate the activities of the heart and kidneys. The major functional properties of pepper are analgesic, anti-pyretic, anti-oxidant and anti-microbial.

Antioxidant Properties of Black Pepper:

Free radicals are unstable molecules that can damage our cells. Excessive free radicals are formed from exposure to pollution, smoke, and sun rays. Excess free radical damage may lead to major health problems. It has been linked to premature aging, Inflammation heart diseases and certain cancers.

Black pepper is rich in a plant compound called piperine, which studies have found to have potent antioxidant properties. Black pepper can help repair that damage and in turn, help reduce the risk of cancer and other diseases.

Studies suggest that a diet high in antioxidants may help prevent or delay the damaging effects of free radicals.

Fenugreek, Curry Leaves, Cumin Seeds, coriander, cinnamon, chilies, cardamom, aniseeds are also some of the commonly used spices known for antioxidant benefits.

Black Pepper for Cholesterol and Heart health:

Black Pepper and Blood Sugar:

Diabetes mellitus is a metabolic disorder and emerging pandemic of the 21st century. Piperine, the chief alkaloid present in Piper nigrum (black pepper), has a wide array of uses in alternative and complementary therapies. The effect of piperine on blood glucose level was studied in alloxan-induced diabetic mice in acute and subacute study models.

Studies suggest that piperine may help in reducing blood sugar levels. It was observed that consumption of the dietary supplement was associated with a significantly greater decrease in insulin resistance.

Some of the other spices which may be helpful to control diabetes are Garlic, Fenugreek, Curry Leaves, Cumin Seeds, Coriander, Cloves, Bay Leaves, Basil.

Black Pepper Benefits Cancer Patients:

Cancer is a genetic disease characterized by unregulated growth and dissemination of malignantly transformed neoplastic cells. The process of cancer development goes through several stages of biochemical and genetic alterations in a target cell.

Piperine is an active alkaloid with an excellent spectrum of therapeutic activities such as anti-oxidant, anti-inflammatory, immunomodulatory, anti-asthmatic, anti-convulsant, anti-mutagenic, antimycobacterial, anti-amoebic, and anti-cancer activities.

Piperine can play an important role in regulating cancer cell proliferation and are considered as potential targets for the treatment of cancer. Piperine is also known to affect cancer cells in variety of other ways such as influencing the redox homeostasis, inhibiting cancer stem cell (CSC) self-renewal and modulation of ER stress and autophagy. Piperine can reverse multidrug resistance (MDR) in cancer cells and acts as bioavailability enhancer for many chemotherapeutic agents.

Some findings suggest that piperine may be a potential agent for the prevention and treatment of human breast cancer, colon cancer, and prostate in men. Piperine has also shown promising effects in laboratory studies for reversing multidrug resistance in cancer cells which needs further studies.

Garlic, Fenugreek, Curry Leaves, Cumin Seeds, Cloves, Cinnamon, Chilies, Cardamom, Bay Leaves are also commonly used spices which are known to be helpful in tumor or cancers.

Black Pepper Benefits Brain Health:

Chronic inflammation plays a major role in the development of various neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, brain tumor, and meningitis. Why these diseases are more common among people from some countries than others is not fully understood, but lifestyle factors have been linked to the development of neurodegenerative diseases. For example, the incidence of certain neurodegenerative diseases among people living in the Asian subcontinent, where people regularly consume spices, is much lower than in countries of the western world. Extensive research over the last 10 years has indicated that nutraceuticals derived from such spices as turmeric, red pepper, black pepper, licorice, clove, ginger, garlic, coriander, and cinnamon target inflammatory pathways, thereby may prevent neurodegenerative diseases.

In a study it was found that the administration of the plant extract significantly improved memory performance and exhibited antioxidant potential. Results suggest that the plant extract ameliorates amyloid beta(1-42)-induced spatial memory impairment by attenuation of the oxidative stress in the rat hippocampus.

Piper nigrum prove to be effective for prevention of Alzheimer’s disease and Parkinson’s disease. A study in rats with Alzheimer’s disease found that piperine improved memory. Piperine extract has been linked to decrease in the formation of amyloid plaques, which are dense clumps of damaging protein fragments in the brain that have been linked to Alzheimer’s disease.

Some other commonly used spices known to aid memory are Fenugreek, Black Pepper, Mint, Ginger, Cumins, Cinnamon, Bay Leaves and Chilies.

Black Pepper is Anti-Inflammatory:

Research has revealed that the major risk factors for most chronic diseases are infections, obesity, alcohol, tobacco, radiation, environmental pollutants, and diet. It is now well established that these factors induce chronic diseases through induction of inflammation. Inflammation could be either acute or chronic. Acute inflammation persists for a short duration and is the host defense against infections and allergens, whereas the chronic inflammation persists for a long time and leads to many chronic diseases including cancer, cardiovascular diseases, neurodegenerative diseases, respiratory diseases, etc.

Studies indicate that cancer incidence in countries such as India where spices are consumed daily is much lower (94/100,000) than those where spices are not consumed such as United States (318/100,000), suggesting the potential role of spices in cancer prevention.

Many laboratory studies suggest that piperine, the main active compound in black pepper, may effectively fight inflammation. Results suggest that piperine has anti-inflammatory, antinociceptive, and antiarthritic effects in an arthritis animal model. Thus, piperine should be further studied with regard to use either as a pharmaceutical or as a dietary supplement for the treatment of arthritis.

In rats, piperine significantly reduced nociceptive and arthritic symptoms at days 8 and 4, respectively. Studies have shown that piperine significantly reduced the inflammatory area in the ankle joints.

Some studies also suggest that piperine effectively treats asthma.

Black Pepper Boosts Nutrient Absorption:

Black pepper can enhance the absorption and function of certain nutrients and beneficial compounds. In particular, it may improve the absorption of curcumin, an active ingredient in the popular anti-inflammatory spice turmeric. One study found that taking 20 mg of piperine with 2 grams of curcumin improved the availability of curcumin in human blood by 2,000%

Research also shows that black pepper may improve the absorption of beta-carotene — a compound found in vegetables and fruits that your body converts to vitamin A. Beta-carotene functions as a powerful antioxidant that may combat cellular damage, thus preventing conditions like heart disease.

Black Pepper for Digestion & Weight Loss:

Black pepper may promote proper stomach function. Black pepper stimulates the entire digestive system, from the salivary glands to the large intestine including the all-important digestive juices such as bile and acids that help digest our food.

Since black pepper enhances digestion, it can go a long way in helping weight loss. The breakdown of fat cells can be supported by the outer layer of the peppercorn, making it easier to be processed by the body, so black pepper can help you lose weight more easily.
