The strong enduring nature of the wood has led to it being chosen for the construction of dwelling places, ships and cathedrals, including Salisbury Cathedral in the UK where it can be seen to be structurally sound over 800 years after its construction (12).<\/span>\r\n\r\nIt has been said that an oak tree is the ideal place to sit to calm your nerves and unravel problems that are affecting your well-being. In the Ogham, an ancient British and Irish language also known as the \u2018Celtic tree alphabet\u2019, oak represents the word Duir which is derived from the Gaelic word for \u2018door\u2019. Oak energy is associated with accessing the doorway to our inner strength and peace when we need it most (13).<\/span>\r\n\r\nOak flower essence is indicated for individuals who have steadfastly remained strong against adversity but who are reaching the limit of their endurance (14). These individuals may also benefit from <\/span>adaptogenic<\/span><\/a> herbs.<\/span>\r\n\r\nOak has been multiply immortalised in prose and verse including by John Keats (15).<\/span>\r\n\r\n\u201cThose green-robed senators of mighty woods,<\/em>\r\n<\/span>Tall oaks, branch-charmed by earnest stars,\r\n<\/span><\/em>Dream, and so dream all night without a stir\u2026<\/em>\u201d<\/span>\r\n\r\n(John Keats, from Hyperion, Book 1)<\/span>","tradtional_uses":"[caption id=\"attachment_11977\" align=\"alignright\" width=\"453\"]\"Green Green oak leaves (Quercus robur<\/em>)[\/caption]\r\n\r\nOak has been used as medicine since the times of Hippocrates, Galen and Dioscorides. Records indicate it was considered effective for the treatment of diarrhoea, excessive uterine bleeding and the spitting of blood (5).<\/span>\r\n\r\nCulpeper (1653) advised that the inner bark of the oak tree along with the thin skin covering the acorn be used to \u201cstay the spitting of blood, and the bloody flux. A decoction of the bark and powdered cups was given \u201cto stay vomiting, bleeding at the mouth or other fluxes of blood in men or women\u201d (16).<\/span>\r\n\r\nOther traditional herbalists claim the skin of the acorn to be effective against the spitting of blood and finely powdered oak bark is said to have been proven beneficial in the early stages of consumption after it was noted that working tanners appeared to be exempt from contracting this disease (17).<\/span>\r\n\r\nHomeopathically oak is indicated for chronic alcoholism and drunkenness; it is considered to be an antidote for alcohol intoxication and may be given to control cravings for alcoholic beverages (1,5,11, 18).<\/span>","what_practioners_say":"[caption id=\"attachment_11982\" align=\"alignright\" width=\"488\"]\"Old Old oak tree (Quercus robur<\/em>)[\/caption]\r\n\r\nThe high tannin content of oak is the reason it is primarily indicated in conditions that involve an excess of fluids, blood loss or tissues that are damaged or lack tone. The astringency that results from the action of these constituents creates a barrier protecting the underlying tissue from infection.\u00a0\u00a0<\/span>\r\n

Digestive system<\/h3>\r\nWithin the digestive system oak is considered to be specific in the primary treatment of cases of acute diarrhoea including dysentery (7,19), where it clearly demonstrates its ability to reduce excess fluids. Adequate fluid intake is essential to maintain during episodes of acute diarrhoea and supplementary electrolytes may also be recommended in some situations.\u00a0<\/span>\r\n\r\nIts benefits for this system are also evidenced in the treatment of disorders affecting the mouth such as inflammation or bleeding of the gums (8,10,19) where, as a mouthwash, it tightens tissues that lack tone whilst reducing the risk of potential infection.<\/span>\r\n

Respiratory system<\/h3>\r\nOak could be included in a prescription for conditions of the upper respiratory system where there is seen to be an excess of fluid such as catarrh or congested sinuses (10).\u00a0<\/span>\r\n\r\nConditions affecting the throat including tonsillitis, pharyngitis and laryngitis, particularly when tissues are inflamed, appear boggy and infection is present, may benefit from the inclusion of oak bark in gargle for its astringent and microbial effects (6,11,20).<\/span>\r\n\r\nIts styptic action has been demonstrated through its ability to stop nosebleeds when administered topically as a snuff (10) and it may show benefits in reducing the size of nasal polyps when administered similarly or, alternatively, as a nasal spray alongside other anti-inflammatory, astringent or mucous membrane restorative herbs specific to the tissues of the nasal passages and sinuses.<\/span>\r\n

Cardiovascular system<\/h3>\r\nAs a remedy for the cardiovascular system, the benefits of oak are most evident where there is venous insufficiency resulting in conditions such as varicose veins and haemorrhoids. Here the ability of oak to tighten and tone tissues is clearly demonstrated when applied topically to the affected area as a lotion (6,10) or, in the case of haemorrhoids a decoction may instead be used as an enema (11,20).<\/span>\r\n\r\n[caption id=\"attachment_11981\" align=\"alignleft\" width=\"476\"]\"Oak Oak tree leaves (Quercus robur<\/em>)[\/caption]\r\n

Gynaecological system<\/h3>\r\nOak is indicated in cases of both menorrhagia (heavy menstrual loss) and leucorrhoea (non-infective white vaginal discharge). However, there are many other herbs that a modern herbal practitioner may alternatively turn to when treating these conditions such as <\/span>yarrow<\/span><\/a> (<\/span>Achillea millefolium<\/span><\/i>), lady\u2019s mantle (<\/span>Alchemilla vulgaris<\/span><\/i>), shepherd\u2019s purse (<\/span>Capsella bursa-pastoris<\/span><\/i>), <\/span>raspberry leaf<\/span><\/a> (<\/span>Rubus idaeus<\/span><\/i>)<\/span> and white dead nettle (<\/span>Lamium alba<\/span><\/i>).\u00a0 Additional herbs may also be added to a prescription to alleviate the cramping and pain that often accompanies heavy periods.\u00a0<\/span>\r\n\r\nHeavy menstrual bleeding is often associated with the perimenopausal stage of an individual\u2019s life or with conditions such as endometriosis, fibroids and uterine polyps for which investigations may be recommended in order that the underlying dysfunction or disease process can be addressed rather than merely palliating the symptoms.<\/span>\r\n\r\nUse of any herbs rich in tannins should be used selectively and for restricted amounts of time due to their effect of gut absorption of nutrients and minerals including iron, particularly given that any condition featuring regular blood loss as a symptom is associated with an increased risk of iron-deficiency anaemia.<\/span>\r\n\r\nShould any acute condition not resolved within acceptable time parameters or symptoms become chronic then seeking further professional medical advice is strongly recommended. This might include an appointment with a GP, practice nurse or other healthcare provider.

These effects may be potentially attributed to the rejuvenation of mitochondrial function that has been evidenced following Robuvit supplementation (6,23).\u00a0<\/span>\r\n\r\nResearch into the anti-inflammatory action of ellagitannins found in herbs including oak bark, meadowsweet (<\/span>Filipendula ulmaria<\/span><\/i>), raspberry leaf (<\/span>Rubus idaeus<\/span><\/i>) and herb Robert (<\/span>Geranium robertianum<\/span><\/i>) has indicated they may have a key role to play as a source of bioavailable gut microbiota metabolites shown to demonstrate anti-inflammatory activity (24).<\/span>\r\n\r\nA 2016 study concluded there is sufficient evidence to suggest that oak bark may have a role to play in the mediation of allergic reactions. An oak bark decoction was demonstrated to inhibit degranulation and the release of cytokines from basophilic and mast cells in <\/span>in vitro<\/span><\/i> trials. Further research is required, however, this could potentially indicate a role for the topical use of oak in the management of allergic reaction (25).\u00a0<\/span>\r\n\r\nAn earlier study in 2013 investigated the potential benefits of <\/span>Quercus acutissima, <\/span><\/i>commonly known as saw-tooth oak which is native to China, Tibet, Korea and Japan, in the prevention of allergic asthma using an ethanol extract of the acorn rather than the bark as is most commonly seen. As foods derived from acorns are commonly available in the parts of the world this species of oak is native to, the study was intended to explore whether the consumption of acorns could be promoted as an anti-inflammatory health-food. The results of this work suggested that the acorn of <\/span>Q. acutissima <\/span><\/i>may have anti-inflammatory effects that are beneficial in the prevention of allergic asthma (26).<\/span>\r\n\r\nAnother study utilising a part of oak other than the bark investigated the therapeutic efficacy of oak gall in a double-blind randomised controlled trial into its effectiveness and safety for treating bacterial vaginosis when compared to the standard treatment of metronidazole vaginal gel. The results of these trials indicate that a vaginal cream made from oak gall was equally effective as treatment with metronidazole gel based on symptom score after one week of treatment. Furthermore, none of the oak gall group experienced any adverse effects whereas 7.7% of the women using metronidazole gel reported vaginal burning (27).<\/span>\r\n\r\nAs antibiotics are increasingly seen to reduce in efficiency as resistant bacterial strains continue to develop, there has arisen a need to identify alternative sources of antimicrobials including those that are plant-derived (28). Studies involving an aqueous (water-based) extraction of oak indicate that it has an effective antimicrobial action and may have a part to play in the solution to antibiotic resistance (29).<\/span>","did_you_know":"The etymology of the Latin name for the oak species \u2018<\/span>Quercus\u2019 <\/span><\/i>is said to be derived from the Celtic words <\/span>quer <\/span><\/i>and <\/span>cuez<\/span><\/i> which translates as \u2018fine tree\u2019(17).<\/span>\r\n\r\nAlongside its other traditional uses, oak has been synonymous with the process of tanning leather and the making of barrels for the storage of wines and spirits (30).<\/span>\r\n\r\nUntil around a hundred years ago, oak galls were used to produce ink (30). <\/span>","additional_information_right":{"illustration":238022},"additional_information_left":{"botany":"The oak is a large, spreading deciduous tree demonstrating extreme longevity of 800 years or more which may grow to over 30\u201340\u00a0 metres in its lifetime (35,36).\u00a0<\/span>\r\n\r\nIt has rugged bark but hairless twigs and leaves, initially a pale yet almost luminous green but darkening as the year progresses.
