ISLAMABAD, April 03 (Online): According to a new study, sea buckthorn berries, which have been used as medicinal plants for centuries, contain powerful antioxidants.
\nThe findings showed encouraging signs for sea buckthorn berries for treating diabetes and obesity during in vitro tests.
\nHarsh coastal environments in which sea buckthorn berries grow may cause them to produce more antioxidants in response to their environmental stressors.<\/p>\n
Sea buckthorn joins a growing list of potent nutraceuticals whose long-held medicinal value is being confirmed by modern science.
\nA new study from Memorial University in Newfoundland, Canada, has identified what may be an antioxidant powerhouse in a shrub that grows in coastal areas in Newfoundland.<\/p>\n
The study asserts the berries from the plant sea buckthorn have unique nutritional characteristics that have the potential to treat diabetes and obesity.<\/p>\n
The findings were recently published in the Journal of the Science of Food and AgricultureTrusted Source.<\/p>\n
This is not the first time sea buckthorn berries have been identified as having significant value for human health. The berries are already popular in Asia and have also been used for treating arthritis and other inflammatory conditions in Europe.<\/p>\n
Sea buckthorn berries contain powerful antioxidants that inhibit or prevent damage caused to the body\u2019s cells by free radicals. (Free radicals are believed to be products of environmental and other stressors.)<\/p>\n
The shrub\u2019s berries and leaves have been widely used for supporting nutrition and have been used as pharmaceuticals.<\/p>\n
Health benefits of sea buckthorn berries
\nDue to their health properties, Canadian governmental agencies introduced sea buckthorn to the country in the early 2000s. Preliminary research at that time suggested the plant had vast commercial potential.<\/p>\n
The plant\u2019s oil is also a potent sourceTrusted Source of omega-3 and omega-6 fatty acids, polyphenols, and vitamins E, B, and A.<\/p>\n
According to Dr. Menka Gupta, a functional medicine doctor with Nutra Nourish, not involved in the study, sea buckthorn berries \u201chave been used for centuries in traditional medicine in Tibet, China, and several other Asian and European countries.\u201d<\/p>\n
\u201cThe most documented use cases are for digestive health, stomach and intestinal problems, cardiovascular health, skin diseases, and ulcers,\u201d Dr. Gupta told Medical News Today.<\/p>\n
The authors of the present study report the promising findings of sea buckthorn berries for treating diabetes and obesity was observed in vitro.<\/p>\n
Michelle Routhenstein, a registered dietitian and nutritionist at EntirelyNourished.com, not involved in the study, cited the vitamins C and E that sea buckthorn contains, as well as \u201cflavonoids, carotenoids, and phenolic compounds, along with their dietary fiber content.\u201d<\/p>\n
\u201cThese may play a role in their potential effects on diabetes cells by reducing oxidative damage and inflammation, potentially improving insulin sensitivity and glucose metabolism,\u201d Routhenstein explained.<\/p>\n
Similarly, in combating obesity, these antioxidants and dietary fiber may help mitigate oxidative stress and inflammation, supporting metabolic health and aiding in weight management efforts.<\/p>\n
\u201cDue to its combination of anti-inflammatory and antimicrobial properties, [sea buckthorn] can have a positive influence on gut health. Better gut health has a positive impact on metabolic health, potentially helping manage diabetes and obesity.\u201d<\/p>\n

More evidence supporting plant-based nutraceuticals
\nDiscovering medicinal properties in plants is often a carryover from their traditional use before physicians\u2019 experience of the plants\u2019 benefits was supplanted by modern scientific studies.<\/p>\n
Dr. Gupta listed a few common plant-based nutraceuticals as examples:<\/p>\n
turmeric
\nginger
\ngreen tea
\nblueberries
\nchia seeds
\nflax seeds
\n\u201cThey contain certain bioactive compounds which provide health benefits through various mechanisms such as antioxidant properties, anti-inflammatory effects and how they impact gut health.\u201d<\/p>\n
\u201cThey are also shown to improve immune function. Polyphenols found in mentioned foods can improve vascular health and reduce the risk of cardiovascular disease,\u201d Dr. Gupta added.<\/p>\n
Routhenstein cited several other modern nutraceuticals:<\/p>\n
ResveratrolTrusted Source \u2014 found in black grapes, certain berries, and peanuts, has antioxidant properties that may benefit heart health by reducing inflammation, improving blood flow, and protecting against oxidative damage to blood vessels.
\nAstaxanthinTrusted Source \u2014 a carotenoid pigment abundant in algae and seafood such as salmon and shrimp, has demonstrated anti-inflammatory, and vasodilatory effects.
\nLignansTrusted Source \u2014 from flaxseeds and sesame seeds have antioxidant properties that may help support heart health by reducing inflammation and oxidative stress.
\nPlant sterols and stanolsTrusted Source \u2014 naturally occurring in fruits, vegetables, nuts, and seeds, may help lower LDL cholesterol levels by inhibiting cholesterol absorption in the intestines, ultimately reducing circulating LDL cholesterol.<\/p>\n
Marine sources of antioxidants
\nSea buckthorn is a hardy, thorny, deciduous shrub, typically thriving along windswept coastlines.<\/p>\n
There are numerous coastal plants with strong antioxidant properties, said Dr. Gupta, including cranberries, rosemary, and lavender.<\/p>\n
Routhenstein cited several more: \u201cThe young leaves of Hibiscus tiliaceus, Syzigium corymbosa, Calophyllum inophyllum, and Colubrina asiatica \u2014 commonly known as beach hibiscus, water apple, Alexandrian laurel, and Asian snakewood respectively \u2014 have been shown to also provide antioxidant properties.\u201d<\/p>\n
Routhenstein and Dr. Gupta suspected coastal climates may have a unique ability to produce powerful antioxidants.<\/p>\n
\u201cI would think that the challenging conditions under which coastal plants grow, such as high-salt soil, variable moisture, and poor nutrient content, probably increases oxidative stress in these plants,\u201d Dr. Gupta said.<\/p>\n
\u201cThis leads to an adaptation response by these plants \u2014 leading to higher levels of antioxidant production,\u201d Dr. Gupta said, from which we may benefit.<\/p>\n
In any event, these are tough plants, and they are not exclusively found along coastlines, but also in other inhospitable environments.<\/p>\n
\u201cA few years ago, I was surprised to see Buckthorn berries growing wildly in Ladakh, India,\u201d Dr. Gupta recalled, noting Ladakh is the highest plateau in the country. \u201c[Sea buckthorn] is considered drought resistant and can withstand extreme temperatures,\u201d she noted.<\/p>\n","protected":false},"excerpt":{"rendered":"
