Kādi ir Ginkgo Biloba ieguvumi?

1. Var mazināt psihisko traucējumu simptomus

Ginkgo var palīdzēt mazināt psihisku traucējumu simptomus, piemēram, Alcheimera slimību un demenci (1). Pekinas Ķīniešu medicīnas universitātes veiktais pētījums atklāja, ka ginkgo ekstrakts var palielināt funkcionālās spējas tiem, kam ir Alcheimera slimība, ja to lieto kopā ar parasto medicīnu (2).

Citā pētījumā konstatēts, ka ginkgo ekstrakts ir efektīvs ar demenci saistīto simptomu ārstēšanā (3). Daži anekdotiski pierādījumi liecina, ka ginkgo var arī uzlabot asins plūsmu smadzenēs (4). Vēl viens Berlīnes Brīvās universitātes veiktais pētījums atklāja, ka ginkgo ekstrakts var uzlabot demences slimnieku stāvokli (5). Epilepsija ir izplatīts nopietnu kognitīvo traucējumu cēlonis. Vienā žurku pētījumā tika norādīts, ka ginkgo ekstrakts varētu uzlabot kognitīvo funkciju, mācīšanos un atmiņu (6).

2. Var palīdzēt ārstēt trauksmi

Ginkgo biloba ekstrakts var mazināt trauksmes un stresa simptomus. Ekstrakts tika izmantots ķīniešu tradicionālajās augu izcelsmes zālēs neirodeģeneratīvo traucējumu ārstēšanai (7). Pētījumos ar dzīvniekiem apgalvots, ka ginkgo biloba ekstrakta antioksidantu saturs var palīdzēt mazināt trauksmes simptomus un citus kognitīvos traucējumus (8), (9).

Vienā pētījumā 107 cilvēku grupa, kas tika ārstēta ar lielu ginkgo devu, ziņoja par trauksmes simptomu samazināšanos (10). Tomēr ir vajadzīgi vairāk pētījumu, lai vēl vairāk izprastu šo ginkgo biloba priekšrocību.

3. Maijs var cīnīties ar iekaisumu

Ginkgo spēj mazināt dažādu apstākļu izraisītu iekaisumu. Taivānas Nacionālās universitātes veiktais pētījums atklāja, ka ginkgo biloba ekstrakts var samazināt dzīvnieku un cilvēku šūnu iekaisuma marķierus (11), (12), (13). Ir arī citi iekaisuma apstākļi ginkgo ekstrakts var palīdzēt ārstēt. Tie ietver:

• Artrīts: Pētījumā, kas tika veikts ar žurkām, tika konstatēts, ka ginkgo ekstrakts varētu palīdzēt mazināt artrītu (14).
• Insults: Ginkgo biloba ekstrakts ir ieteikts pacientiem ar akūtu išēmisku insultu (pēkšņs asinsrites zudums smadzeņu zonā). Zālēm tiek teikts, ka tām piemīt neiroprotektīvās īpašības, kas palīdz uzlabot kognitīvo funkciju pacientiem (15).
• Kairinātu zarnu slimība (IBD): Kairas universitātes veiktais pētījums atklāja, ka kurkumīns un ginkgo varētu būt efektīvi IBD profilaksē un ārstēšanā (16).

Nepieciešams vairāk cilvēku pētījumu, lai izprastu ginkgo ekstrakta nozīmi dažādu slimību ārstēšanā.

4. Var atbalstīt acu veselību

Daži agrīni pētījumi norāda, ka papildināšana ar ginkgo var palielināt asins plūsmu acīs. Tas varētu būt potenciāls glaukomas ārstēšanas līdzeklis. Tomēr šajā ziņā trūkst pārliecinošu pierādījumu (17). Neliels pētījums, ko veica Londonas Higiēnas un tropu medicīnas skola, atklāja, ka ginkgo ekstrakts var labvēlīgi ietekmēt redzi. Turpmāki izmēģinājumi ir pamatoti (18).

Ginkgo biloba ekstrakts ir arī potenciāls, lai ārstētu parastās spriedzes glaukomu (19). Ir vajadzīgi vairāk pētījumu, lai noteiktu, vai ginkgo patiešām efektīvi veicina redzes veselību.

5. Var uzlabot sirds veselību

Ginkgo var palielināt asins plūsmu, veicinot asinsvadu paplašināšanos. To lieto, ārstējot jautājumus, kas saistīti ar sliktu asinsriti. Ginkgo spēj palielināt asins plūsmu uz dažādām ķermeņa daļām.

Ginkgo biloba ekstrakts (GBE) ir daudzsološs terapeitisks līdzeklis sirds un asinsvadu un išēmisko slimību ārstēšanai. Tas veicina asinsvadu (asinsvadu) veselību (20). Hebei Medicīnas universitātes Otrās slimnīcas veiktais pētījums atklāja, ka ginkgo ekstrakts uzlabo koronāro artēriju cirkulāciju pacientiem ar koronāro artēriju slimību (21). Tas arī parādīja tādu pašu efektu gados vecākiem cilvēkiem (22). Šis ekstrakts aizsargā sirds veselību. Tas var arī palīdzēt ārstēt neiroloģiskus un sirds-cerebrovaskulārus traucējumus (23), (24), (25).

Ginkgo ekstrakts var būt noderīgs diabētiskā miokarda bojājuma ārstēšanā (jautājumi, kas saistīti ar sirds membrānām) (26).

6. Var uzlabot smadzeņu darbību

Ginkgo ir vairākkārt novērtēts par spēju mazināt trauksmi, stresu un citus simptomus, kas saistīti ar Alcheimera slimību un ar vecumu saistītu kognitīvo pasliktināšanos. Liberty University universitātes Veselības zinātņu departamenta veiktais pētījums atklāja, ka papildināšana ar ginkgo ekstraktu var palielināt garīgo veiktspēju (27).

Vēl viens Minhenes universitātes veiktais pētījums atklāja, ka zāle uzlabo veselīgu brīvprātīgo garīgo darbību (28). Anekdotiski pierādījumi liecina, ka ginkgo var būt galvenā loma asins plūsmas uzlabošanā smadzenēs.

7. Maija palīdzības depresijas ārstēšana

Ginkgo ekstraktam piemīt pretiekaisuma īpašības, kas var palīdzēt depresijas ārstēšanā. Pētījumā konstatēts, ka papildināšana ar ginkgo ekstraktu var palīdzēt ārstēt depresijas simptomus (29). Tomēr šajā ziņā ir jāveic vairāk pētījumu.

8. Var ārstēt galvassāpes un migrēnu

Ginkgo biloba var mazināt iekaisumu un potenciāli palielināt asinsriti smadzenēs. Tas var ārstēt noteiktus galvassāpju un migrēnas veidus. Garšaugi, kas cīnās ar iekaisumu, tradicionālajā ķīniešu medicīnā ir diezgan populāri kā migrēnas un galvassāpju ārstēšana (30). Tomēr ir maz pētījumu, lai pamatotu šo apgalvojumu.

Pētījumā apspriests ginkgolīds B, kas ir augu sastāvdaļa, kas iegūta no ginkgo biloba koka lapām. Tika konstatēts, ka sastāvdaļa palīdz novērst migrēnu un galvassāpes jaunā vecumā (31). Citā pētījumā tika atklāts, ka ginkgolidu B var izmantot, lai samazinātu migrēnas ar auru smagumu un biežumu (migrēnas ar redzes izmaiņām) (32).

9. Var uzlabot astmas un HOPS simptomus

The anti-inflammatory properties of ginkgo biloba extract may treat symptoms associated with respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). A study conducted by Jilin University found that the anti-inflammatory compounds available in ginkgo may reduce inflammation in the airways (33). In another study, asthma patients treated with ginkgo extract showed better improvement in their condition compared to patients who received conventional medication alone (34).

In another study, a group of 100 COPD patients over 50 years of age who consumed a mixture of Chinese herbs (including ginkgo) reported a reduction in bronchitis and cough (35).

10. May Reduce PMS Symptoms

Ginkgo biloba may help reduce PMS symptoms. A study found a reduction of PMS symptoms by 23% after consuming ginkgo extract (36). Further information on the safety of the herb in this regard is needed.

Ginkgolide B has also been associated with a reduction in PMS symptoms (37).

11. May Treat Sexual Dysfunction

Ginkgo biloba extract (GBE) may facilitate blood flow and influence nitric oxide systems, and has a relaxant effect on smooth muscle tissue. These processes are important for sexual response in women. GBE may have the potential to boost sexual health in women (38).

A study found that ginkgo extract has the ability to improve blood levels of nitric oxide (39). This may help improve women’s sexual function too. However, we need more research to further understand this mechanism of ginkgo.

12. May Help Reduce Obesity

Ginkgo biloba extract (GBE) may help reduce obesity. One rat study stated that ginkgo biloba extract could be efficient in preventing and treating obesity-induced insulin signaling impairment (40). GBE may improve insulin resistance and reduce body weight gain (41). GBE may also represent a potential alternative therapy for menopause-related obesity (42).

A study found that ginkgo biloba leaves could improve blood lipid parameters. They could be used in the treatment of dyslipidemia (abnormal amount of lipids in the blood) (43). Ginkgo biloba extract reduces oxidative stress in diet-induced obese rats (44). It could also exhibit anti-obesogenic effects in white adipose tissue of rats (45).

More long-term studies are needed to understand the anti-obesogenic effects of ginkgo extract on humans.

13. May Improve Skin Health

Ginkgo biloba is said to possess anti-aging effects too. The ginkgo leaf extract contains quercetin and kaempferol (natural plant flavonoids that act as antioxidants) that help fight free radicals. They may reduce signs of skin aging. Ginkgo also had synergistic effects with green tea on improving skin barrier function and elasticity (46).

14. May Boost Hair Growth

Ginkgo biloba has been proven to potentially help slow down hair loss. It may also promote hair growth. However, these studies have been conducted on mice alone (47).

These are the benefits of ginkgo biloba. In the following section we will look at the herb’s ideal dosage.

Dosage And Forms Of Ginkgo Biloba

Ginkgo biloba is available in various forms such as liquid extracts, tablets, capsules, and dried leaves/tea. It seems to be most effective when taken in several doses throughout the day (total daily dosage being 120–240 mg). Ensure you do not take the raw form of ginkgo, as it can be poisonous.

Ginkgo may take up to 4 to 6 weeks to show any results. A common dose of 40 milligrams of extract three times daily is recommended to those with dementia. For improving cognitive function in healthy people, 120 milligrams to 600 milligrams of the extract may be used. These values are based on anecdotal evidence. Consult your doctor for more information.

Though ginkgo biloba is generally safe for use, it does have a few side effects that you need to keep in mind. Check them out in the next section.

What Are The Side Effects Of Ginkgo Biloba?

Excess intake of ginkgo biloba may cause several adverse effects. These may include allergies, headaches, stomach pain, diarrhea, dizziness, nausea, and some drug interactions.

In some cases, intake of the herb can cause serious harm. Individuals who are allergic to plants with alkylphenols, pregnant and breastfeeding women, and people with epilepsy should avoid intake. People who are on medications must consult with their doctor before taking ginkgo.

High exposure to ginkgo may increase the risk of breast and colorectal cancers in some individuals. Also, ginkgo does not seem to reduce the risk of other forms of cancer (48). Some anecdotal evidence suggests that ginkgo has the potential to interact with certain medications like blood thinners (aspirin, warfarin) and antidepressants.

Ginkgo biloba may also have other risks associated with it.

Risks

Ginkgo is generally considered safe for healthy people when used in limited amounts for up to six months. The Food and Drug Administration (FDA) doesn’t regulate ginkgo supplements or most other drugs that contain the herb (49).

Some anecdotal evidence suggests that ginkgo may lower blood sugar levels. Hence, use with caution if you have diabetes.

Eating raw or roasted ginkgo seeds may be poisonous and may lead to adverse effects. Research is limited here, though.

Conclusion

Ginkgo biloba is one of the oldest plant species on the planet. It is said to possess several anti-inflammatory and antioxidant properties that offer health benefits. The herb helps reduce symptoms of psychiatric disorders, treats anxiety, and fights inflammation. However, excess intake of ginkgo extract may lead to several adverse effects. Most of the research related to this herbal extract is still ongoing. Consult your doctor before including this herb into your routine.
