Pungency
Pungency ( ), commonly referred to as spiciness, hotness or heat, is a sensation that contributes to the flavor of certain foods such as chili peppers. Highly pungent foods may be experienced as unpleasant. The term piquancy ( ) is sometimes applied to foods with a lower degree of pungency that are "agreeably stimulating to the palate". In addition to chili peppers, ''piquant'' ingredients include wasabi, horseradish and mustard. The primary substances responsible for pungency are capsaicin (in chilis), piperine (in peppercorns) and allyl isothiocyanate (in radishes, mustard and wasabi). Terminology In colloquial speech, the term "pungency" can refer to any strong, sharp smell or flavor. However, in scientific speech, it refers specifically to the "hot" or "spicy" quality of foods like chili peppers and garlic. It is the preferred term by scientists as it eliminates the ambiguity arising from use of "hot", which can also refer to temperature, and "spicy", which can also refer ...

Allspice
Allspice, also known as Jamaica pepper, myrtle pepper, pimenta, or pimento, is the dried unripe berry of ''Pimenta dioica'', a midcanopy tree native to the Greater Antilles, southern Mexico, and Central America, now cultivated in many warm parts of the world. The name ''allspice'' was coined as early as 1621 by the English, who valued it as a spice that combined the flavours of cinnamon, nutmeg, and clove. Contrary to common misconception, it is not a mixture of spices. Several unrelated fragrant shrubs are called "Carolina allspice" ('' Calycanthus floridus''), "Japanese allspice" ('' Chimonanthus praecox''), or "wild allspice" ('' Lindera benzoin''). Production Allspice is the dried fruit of the ''Pimenta dioica'' plant. The fruits are picked when green and unripe, and are traditionally dried in the sun. When dry, they are brown and resemble large, smooth peppercorns. Fresh leaves are similar in texture to bay leaves and similarly used in cooking. Leaves and wood are oft ...

Trigeminal Nerve
In neuroanatomy, the trigeminal nerve (literal translation, lit. ''triplet'' nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for Sense, sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves. Its name (''trigeminal'', ) derives from each of the two nerves (one on each side of the pons) having three major branches: the ophthalmic nerve (V), the maxillary nerve (V), and the mandibular nerve (V). The ophthalmic and maxillary nerves are purely sensory, whereas the mandibular nerve supplies motor as well as sensory (or "cutaneous") functions. Adding to the complexity of this nerve is that Autonomic nervous system, autonomic nerve fibers as well as special sensory fibers (taste) are contained within it. The motor division of the trigeminal nerve derives from the Basal plate (neural tube), basal plate of the embryonic pons, and the sensory division originates in ...

Thiosulfinate
In organosulfur chemistry, thiosulfinate is a functional group consisting of the linkage (R refers to organic substituents). Thiolsulfinates are also named as alkanethiosulfinic (or arenethiosulfinic) acid esters. They are the first of the series of functional groups containing an oxidized disulfide bond. Other members of this family include thiosulfonates (), α-disulfoxides (), sulfinyl sulfones (), and α-disulfones (), of which all (except αdisulfoxides) are known. The thiosulfinate group can occur in cyclic as well as acyclic structures. Thiosulfinate also refers to thiosulfinate anion and its salts. Occurrence A variety of acyclic and cyclic thiosulfinates are found in plants, or formed when the plants are cut or crushed. A well-known thiosulfinate is allicin, one of the active ingredients formed when garlic is crushed. Allicin was discovered in 1944 by Chester J. Cavallito and coworkers. Thiosulfinates containing various combinations of the methyl, n-propyl, ''n''-pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemesthesis
Chemesthesis is the detection of potentially harmful chemicals by the skin and mucous membranes. Chemesthetic sensations arise when chemical compounds activate Sensory receptor, receptors associated with other senses that mediate pain, touch, and Thermoception, thermal perception. These chemical-induced reactions do not fit into the traditional sense categories of taste and Olfaction, smell. Examples of chemesthetic sensations include the burn-like irritation from capsaicin and related compounds in foods like chili peppers; the coolness of menthol in mouthwashes and topical analgesic creams; the stinging or tingling of carbonated beverages in the nose and mouth; the tear-induction of cut onions; and the pungent, cough-inducing sensation in the back of the throat elicited by the oleocanthal in high-quality extra virgin olive oil. Some of these sensations may be referred to as spiciness, pungency, or piquancy. Chemesthetic sensations sometimes arise by direct chemical activation of ...

Pepper Spray
Pepper spray, oleoresin capsicum spray, OC spray, capsaicin spray, mace, or capsicum spray is a Tear gas, lachrymator (tear gas) product containing as its active ingredient the chemical compound capsaicin, which irritates the eyes with burning and pain sensations and so causes them to close, bringing temporary blindness. This blindness allows officers to more easily restrain subjects and permits people in danger to use pepper spray in self-defense for an opportunity to escape. It also causes temporary discomfort and burning of the lungs which causes shortness of breath. Pepper spray is used as a less lethal weapon in Police, policing, riot control, crowd control, and self-defense, including defense against dogs and bears. Pepper spray was engineered originally for defense against bears, cougars, wolves and other dangerous predators, and is often referred to colloquially as bear spray. Kamran Loghman, who developed it for use in riot control, wrote the guide for police departm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Analgesic
An analgesic drug, also called simply an analgesic, antalgic, pain reliever, or painkiller, is any member of the group of drugs used for pain management. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and anesthetic effects. Analgesic choice is also determined by the type of pain: For neuropathic pain, recent research has suggested that classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants may be considered as an alternative. Various analgesics, such as many NSAIDs, are available over the counter in most countries, whereas various others are prescription drugs owing to the substantial risks and high chances of overdose, misuse, and addiction in the absence of medical supervision. Etymology The word ''analgesic'' derive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Topical Medication
A topical medication is a medication that is applied to a particular place on or in the body. Most often topical medication means application to body surface area, body surfaces such as the skin or mucous membranes to treat ailments via a large range of classes including Cream (pharmaceutical), creams, foams, gels, lotions, and ointments. Many topical medications are epicutaneous, meaning that they are applied directly to the skin. Topical medications may also be insufflation (medicine), inhalational, such as asthma medications, or applied to the surface of tissues other than the skin, such as eye drops applied to the conjunctiva, or ear drops placed in the ear, or medications applied to the surface of a Human tooth, tooth. The word ''topical'' derives from Ancient Greek, Greek wikt:τοπικός, τοπικός ''topikos'', "of a place". Justification Topical drug delivery is a route of administering drugs via the Human skin, skin to provide topical therapeutic effects. As sk ...

Ginger
Ginger (''Zingiber officinale'') is a flowering plant whose rhizome, ginger root or ginger, is widely used as a spice and a folk medicine. It is an herbaceous perennial that grows annual pseudostems (false stems made of the rolled bases of leaves) about one meter tall, bearing narrow leaf blades. The inflorescences bear flowers having pale yellow petals with purple edges, and arise directly from the rhizome on separate shoot (botany), shoots. Ginger is in the family (taxonomy), family Zingiberaceae, which also includes turmeric (''Curcuma longa''), cardamom (''Elettaria cardamomum''), and galangal. Ginger originated in Maritime Southeast Asia and was likely domesticated first by the Austronesian peoples. It was transported with them throughout the Indo-Pacific during the Austronesian expansion ( Before Present, BP), reaching as far as Hawaii. Ginger is one of the first spices to have been exported from Asia, arriving in Europe with the spice trade, and was used by ancient Gre ...

Black Pepper
Black pepper (''Piper nigrum'') is a flowering vine in the family Piperaceae, cultivated for its fruit (the peppercorn), which is usually dried and used as a spice and seasoning. The fruit is a drupe (stonefruit) which is about in diameter (fresh and fully mature), dark red, and contains a stone which encloses a single pepper seed. Peppercorns and the ground pepper derived from them may be described simply as ''pepper'', or more precisely as ''black pepper'' (cooked and dried unripe fruit), ''green pepper'' (dried unripe fruit), or ''white pepper'' (ripe fruit seeds). Black pepper is native to the Malabar Coast of India, and the Malabar pepper is extensively cultivated there and in other tropical regions. Ground, dried, and cooked peppercorns have been used since antiquity, both for flavour and as a traditional medicine. Black pepper is the world's most traded spice, and is one of the most common spices added to cuisines around the world. Its spiciness is due to the che ...

Somatosensory
The somatosensory system, or somatic sensory system is a subset of the sensory nervous system. The main functions of the somatosensory system are the perception of external stimuli, the perception of internal stimuli, and the regulation of body position and balance (proprioception). It is believed to act as a pathway between the different sensory modalities within the body. As of 2024 debate continued on the underlying mechanisms, correctness and validity of the somatosensory system model, and whether it impacts emotions in the body. The somatosensory system has been thought of as having two subdivisions; *one for the detection of mechanosensory information related to touch. Mechanosensory information includes that of light touch, vibration, pressure and tension in the skin. Much of this information belongs to the sense of touch which is a general somatic sense in contrast to the special senses of sight, smell, taste, hearing, and balance. * one for the nociception detec ...
