This gives it many uses for inflammatory-type disorders that express themselves with redness, swelling and heat.<\/span>\r\n\r\nOne of its primary uses is in the treatment of contagious febrile disorders with fever and sore throat, <\/span>cough<\/span><\/a>, red eyes, mouth ulcers, irritability and in severe cases, delirium, rashes and subcutaneous bleeding (1).<\/span>\r\n\r\nIt can also be used for interior inflammatory conditions such as intestinal and lung abscesses, lumps and nodules as a result of lymphatic obstruction (1).<\/span>","into_the_heart_of":"[caption id=\"attachment_254989\" align=\"alignright\" width=\"510\"]\"Forsythia Forsythia (Forsythia suspensa<\/em>)[\/caption]\r\n\r\nForsythia was said by the 12th century physician Zhang Yuansu to have three main uses: To drain heat in the Heart channel, to dispel various types of heat from the upper burner, and as the sage-like herb for sores (2). The reasoning for this is based on its physical properties.<\/span>\r\n\r\nIts rounded and pointed shape with a hollow chamber inside resembles a heart, giving it a particular affinity for this organ (2). This manifests in its use for treating high fevers, irritability and delirium and for dispersing clumping that manifests as hot, swollen lumps under the skin (1). It clears this heat by facilitating its passage through the urine, indicating it for painful urinary disorders too.<\/span>\r\n\r\nIts light weight lifts it to the upper and exterior parts of the body, making it a chief herb for venting the heat of fevers and sore throats from early stage, externally contracted febrile disorders (1).<\/span>\r\n\r\nIts function in resolving hot skin conditions also derives from its aforementioned affinity for the Heart, for which the <\/span>Basic Questions<\/span><\/i> says that \u201call painful, itchy sores derive from the Heart.\u201d Additionally, light herbs with empty insides are associated with draining, disseminating and unblocking functions that gives forsythia an ability to disperse clumped heat in the collateral channels (2). These are the visible surface blood vessels which manifest as changes in complexion, including rashes, macula and purpurea as well as subcutaneous bleeding.<\/span>","tradtional_uses":"[caption id=\"attachment_254996\" align=\"alignright\" width=\"515\"]\"Forsythia Forsythia (Forsythia suspensa<\/em>)[\/caption]\r\n\r\nIn traditional Chinese medicine, it is traditionally the fruit which is used in capsule form for the clearance of heat and resolution of toxicity, particularly in the upper body. Its main function is the clearance of wind-heat, referring to externally contracted diseases, such as <\/span>colds and flu<\/span><\/a>, of a \u2018warm\u2019 or \u2018hot\u2019 nature. This means diseases that present with a pronounced fever with only slight chills, a sore throat and <\/span>headache<\/span><\/a> (2).\u00a0<\/span>\r\n\r\nIts second, related function, is to clear heat from the Heart, the organ that stores the spirit and commands the Blood. Therefore, it can be used in cases where a pathogen has progressed further into the body, causing changes in consciousness, or when the Blood itself is heated and pushed out of the vessels causing subcutaneous bleeding, macula and purpurea to appear (1). In Chinese medicine, this is referred to as the nutritive level (<\/span>ying<\/span><\/i>).<\/span>\r\n\r\nForsythia is also described as the sage-like herb for sores, for its capacity to treat a number of skin conditions that result from heat. This includes a number of rashes, sores, lesions, swellings, abscesses, ulcerations (1). This action can also operate internally for the treatment of lung and intestinal abscesses and ulcerations.<\/span>\r\n\r\nRelated to its ability to treat sores is the ability of forsythia to disperse accumulations such as lumps, nodules and furuncles. This can also work internally, dispersing heat accumulation that can lead to the formation of urinary stones, burning or bloody urination. In this case, the heat is boiling away fluids leading to the formation of toxic phlegm that can develop into nodules, lumps and stones, and the dispersing, cooling nature of forsythia enables the obstructed fluids to flow again, reducing or preventing their formation (2).<\/span>","what_practioners_say":"

\"ImmuneImmune system<\/h3>\r\nForsythia is one of the primary herbs for treating fever and inflammation anywhere in the body. It can be used for externally contracted diseases with fever and sore throat, or for internal inflammation such as abscesses. This can be directed with the appropriate combination of other herbs, for which its partnering with <\/span>honeysuckle<\/span><\/a> is the most common and famous. This treats the early stage colds and flu with pronounced fever, slight chills, sore throat and headache. Its effects on the throat can be further enhanced by combining with woad (<\/span>Isatis tinctoria<\/span><\/i>) root or leaf, or with <\/span>burdock<\/span><\/a> (<\/span>Arctium lappa<\/span><\/i>) seeds for tonsillitis (2). <\/span>\r\n\r\nFor internal inflammation resulting in intestinal or lung abscesses, it is often combined with <\/span>honeysuckle<\/span><\/a>, wild <\/span>chrysanthemum<\/span><\/a> (<\/span>Chrysanthemum x morifolium<\/span><\/i>) and <\/span>dandelion<\/span><\/a> (<\/span>Taraxacum officinale<\/span><\/i>) (1). It can even be used for severe inflammatory symptoms with high fever and delirium by combining with other cooling herbs such as <\/span>rehmannia<\/span><\/a> (<\/span>Rehmannia glutinosa<\/span><\/i>), figwort (<\/span>Scrophularia nodosa<\/span><\/i>), bamboo (<\/span>Bambusa<\/span><\/i>) leaves, Chinese goldthread (<\/span>Coptis chinensis<\/span><\/i>) and <\/span>red sage<\/span><\/a> (<\/span>Salvia miltirorrhiza<\/span><\/i>), seen in the formula \u2014 Clear the Nutritive Level Decoction (<\/span>Qing Ying Tang<\/span><\/i>) designed for epidemic diseases (3).\u00a0<\/span>\r\n\r\nHowever, it is important that this herb is not used indiscriminately for colds and flu. Chinese medicine divides contagious diseases into warm and cold types with the most important differentiating factor being whether chills or fever predominates. The cooling nature of forsythia is only indicated in a warm presentation where fever is more pronounced and accompanied by signs such as aversion to heat, sore throat, red eyes, red tongue with a yellow coat and a rapid pulse. Where chills and aversion to cold predominate, accompanied by tightness of the neck and shoulders, and generalised body aches, forsythia should be avoided and warming herbs such as ephedra (<\/span>Ephedra sinica<\/span><\/i>) and <\/span>cinnamon<\/span><\/a> (<\/span>Cinnamomum verum<\/span><\/i>) used instead.<\/span>\r\n

Skin<\/h3>\r\nForsythia is a key herb for sores and used in a number of skin disorders, especially where there are rashes, swellings, lesions, ulcerations and nodules (2). However, it should also be remembered that this is a cooling and dispersing herb without any tonifying properties and so should be avoided when the skin is not hot and red, especially if it is worse for cold. If there is an underlying deficiency, this should also be combined with other herbs to address the deficiency (1,2).<\/span>\r\n

Urinary<\/h3>\r\nIn Chinese medicine, heat trapped in the body must be released somehow, either through sweating, urination or the stool. Forsythia primarily releases heat through the urine, which means that, as a secondary function, it can be used to promote urination through a <\/span>diuretic<\/span><\/a> action, especially where the obstruction is due to heat accumulation. This makes it a supportive herb in cases of burning, painful urination, possibly with the presence of blood due to <\/span>stones<\/span><\/a>, where its <\/span>anti-inflammatory<\/span><\/a> actions can help to ease their passage (1).<\/span>","research":"[caption id=\"attachment_254994\" align=\"alignright\" width=\"515\"]\"Forsythia Forsythia (Forsythia suspensa<\/em>)[\/caption]\r\n

The phytochemistry, pharmacology, pharmacokinetics, quality control, and toxicity of Forsythiae Fructus: An updated systematic review<\/h3>\r\nThis systematic review was conducted to update a previous review on forsythia fruits in 2017. Two hundred and fourty-eight compounds were identified, including 42 phenylethanoid glycosides, 48 lignans, 22 terpenoids, 14 flavonoids, three steroids, 24 cyclohexyl ethanol derivatives, 14 alkaloids, 26 organic acids, 21 volatile oils, and and 24 other compounds.<\/span>\r\n\r\n Pharmacologically, they found evidence of anti-inflammatory, <\/span>antioxidant<\/span><\/a>, antibacterial, antiviral, anti-tumor, neuroprotective, and <\/span>hepatoprotective<\/span><\/a> properties, with the capacity to regulate cytochrome P450, alleviate <\/span>asthma<\/span><\/a>, relieve atopic dermatitis, prevent androgenic alopecia, and assist thermoregulation, provide nephroprotective effects, and reduce ischemic damage. Most of these activities were due to the anti-inflammatory and anti-influenza properties of phenylethanoid glycosides, especially forsythoside A and lignans such as phillyrin (4,5).<\/span>\r\n

Amplifying protection against acute lung injury: Targeting both inflammasome and cGAS-STING pathways by Lonicerae Japonicae Flos-Forsythiae Fructus drug pair<\/h3>\r\nThis <\/span>in vivo<\/span><\/i> and<\/span> in vitro <\/span><\/i>study looked at the common herb pairing of forsythia fruits and honeysuckle flower in the treatment of acute lung injury through a lipopolysaccharide induced mouse model and cultured macrophages. <\/span>\r\n\r\nThey observed an enhanced protective effect from the use of both medicinals compared to each one used alone, attenuating the damage to alveolar structures, pulmonary hemorrhage, and the infiltration of inflammatory cells, approaching the effectiveness of dexamethasone. In cellular models, herbs operated through the same (cGAS-STING and NLRP3) inflammasome pathways but their combined use enhanced the overall effectiveness (6).<\/span>\r\n

Better detoxifying effect of ripe Forsythiae fructus<\/i> over green Forsythiae fructus<\/i> and the potential mechanisms involving bile acids metabolism and gut microbiota<\/h3>\r\nThis study compared effects of the ripe and unripe forms of forsythia fruits in a rat model of a bile duct ligation-induced cholestasis in order to determine the best fruits to use in these models. Forsythia has been used in formulas to treat jaundice since the Han dynasty (~ 210 CE) and while the green fruits are often preferred in formulas to reduce fever, the best type to use in liver conditions remains uncertain. <\/span>\r\n\r\nTheir study showed that the ripe fruits had a better effect at resolving the toxic bile acid accumulation through an indirect mechanism of modulating the gut microbiota, which makes the ripe form a superior choice when treating liver related conditions with bile acid accumulation (7).<\/span>\r\n

Efficacy of Forsythia suspensa<\/i> (Thunb.) Vahl on mouse and rat models of inflammation-related diseases: a meta-analysis<\/h3>\r\nThis meta analysis was conducted on animal studies s and investigated the effect of forsythia fruits on inflammation to date. In a total of 11 papers that met the criteria, they found that forsythia fruit effectively reversed the changes in acute or chronic inflammation indicators in animal models, through the regulation of multiple inflammatory signaling pathways. The disorders investigated included inflammatory injury in the liver, lungs, and colon; oxidative stress; chronic pelvic inflammatory disease; atopic dermatitis; and B16 melanoma growth (8).<\/span>\r\n
