Millised on ginkgo biloba eelised?

1. Võib vähendada psühhiaatriliste häirete sümptomeid

Ginkgo võib aidata vähendada psühhiaatriliste häirete sümptomeid, nagu Alzheimeri tõbi ja dementsus (1). Pekingi Hiina meditsiini ülikooli poolt läbi viidud uuringust selgus, et hõlmikpuu ekstrakt võib suurendada Alzheimeri tõvega inimeste funktsionaalseid võimeid, kui seda kasutatakse koos tavapärase meditsiiniga (2).

Teises uuringus leiti, et hõlmikpuu ekstrakt on efektiivne dementsusega seotud sümptomite ravimisel (3). Mõned anekdootlikud tõendid viitavad sellele, et hõlmikpuu võib parandada ka aju verevoolu (4). Berliini Vabaülikooli teises uuringus leiti, et hõlmikpuu ekstrakt võib parandada dementsusega inimeste seisundit (5). Epilepsia on tõsiste kognitiivsete häirete levinud põhjus. Ühes roti uuringus väideti, et hõlmikpuu ekstrakt võib parandada kognitiivseid funktsioone, õppimist ja mälu (6).

2. Võib aidata ärevust ravida

Hõlmikpuu ekstrakt võib vähendada ärevuse ja stressi sümptomeid. Ekstrakti kasutati hiina traditsioonilises taimeravis neurodegeneratiivsete häirete raviks (7). Loomkatsed kinnitavad, et ginkgo biloba ekstrakti antioksüdantide sisaldus võib aidata vähendada ärevuse sümptomeid ja muid kognitiivseid häireid (8), (9).

Ühes uuringus teatas 107 inimesest koosnev rühm, mida raviti suure ginkgo annusega, ärevussümptomite vähenemisest (10). Hõlmikpuu selle kasu paremaks mõistmiseks on vaja rohkem uuringuid.

3. mai võidelda põletikega

Hõlmikpuu suudab vähendada erinevate seisundite põhjustatud põletikku. Taiwani Riikliku Ülikooli korraldatud uuring näitas, et hõlmikpuu ekstrakt võib vähendada põletiku markereid looma- ja inimrakkudes (11), (12), (13). Raviks võib olla ka ginkgo ekstrakt. Need sisaldavad:

• Artriit: rottidega läbi viidud uuring näitas, et hõlmikpuu ekstrakt võib aidata artriiti leevendada (14).
• Insult: Ginkgo biloba ekstrakti on soovitatud ägeda isheemilise insuldiga (vereringe äkiline kadumine ajupiirkonda) patsientidele. Ürdil on väidetavalt neuroprotektiivsed omadused, mis aitavad parandada patsientide kognitiivseid funktsioone (15).
• Ärritatud soolehaigus (IBD): Kairo ülikooli läbi viidud uuring näitas, et kurkumiin ja hõlmikpuu võiksid olla efektiivsed IBD ennetamisel ja ravimisel (16).

Hõlmikpuuekstrakti rolli mõistmiseks mitmesuguste haiguste ravimisel on vaja rohkem inimtegevuse uuringuid.

4. Võib toetada silmade tervist

Mõnes varasemas uuringus väidetakse, et hõlmikpuu lisamine võib suurendada silmade verevoolu. See võib olla glaukoomi võimalik ravi. Selles osas puuduvad siiski veenvad tõendid (17). Londoni hügieeni ja troopilise meditsiini kooli läbi viidud väikeses uuringus leiti, et hõlmikpuu ekstraktil võib olla nägemisele kasulik mõju. Täiendavad katsed on õigustatud (18).

Ginkgo biloba ekstraktil on potentsiaal ravida ka normaalse pingega glaukoomi (19). Vaja on rohkem uuringuid, et teha kindlaks, kas hõlmikpuu on nägemise tervise edendamisel tõeliselt tõhus.

5. Võib parandada südame tervist

Ginkgo võib suurendada verevoolu, soodustades veresoonte laienemist. Seda on kasutatud kehva vereringega seotud probleemide ravimisel. Ginkgo on võimeline suurendama verevoolu keha erinevates osades.

Ginkgo biloba ekstrakt (GBE) on paljutõotav raviaine südame-veresoonkonna ja isheemiliste haiguste korral. See soodustab veresoonte (veresoonte) tervist (20). Hebei Meditsiiniülikooli teise haigla poolt läbi viidud uuring näitas, et hõlmikpuu ekstrakt parandab pärgarteri haigusega patsientidel koronaararterite vereringet (21). See näitas sama efekti ka eakatel (22). Sellel ekstraktil on südame tervisele kaitsev toime. See võib aidata ka neuroloogiliste ja südame-tserebrovaskulaarsete häirete ravis (23), (24), (25).

Ginkgoekstrakt võib olla kasulik diabeetilise müokardi kahjustuse (südamemembraanidega seotud probleemid) ravis (26).

6. Võib parandada aju funktsiooni

Ginkgot on korduvalt hinnatud selle võime eest vähendada ärevust, stressi ja muid sümptomeid, mis on seotud Alzheimeri tõve ja vanusega seotud kognitiivse langusega. Liberty ülikooli terviseteaduste osakonna poolt läbi viidud uuring leidis, et hõlmikpuu ekstraktiga täiendamine võib suurendada vaimset võimekust (27).

Müncheni ülikooli poolt läbi viidud teises uuringus leiti, et ravimtaim parandab tervete vabatahtlike vaimset toimimist (28). Anekdootlikud tõendid näitavad, et ginkgo võib mängida suurt rolli aju verevoolu parandamisel.

7. Mai depressiooniravi

Ginkgoekstraktil on põletikuvastased omadused, mis võivad aidata depressiooni ravis. Uuringus leiti, et hõlmikpuu ekstraktiga täiendamine võib aidata depressiooni sümptomeid ravida (29). Sellega seoses on siiski vaja rohkem uurida.

8. Võib ravida peavalu ja migreeni

Ginkgo biloba võib vähendada põletikku ja potentsiaalselt suurendada aju verevoolu. See võib ravida teatud tüüpi peavalusid ja migreeni. Põletikuvastased ravimtaimed on hiina traditsioonilises meditsiinis migreeni ja peavalude ravis üsna populaarsed (30). Selle väite toetamiseks on siiski vähe uurimusi.

Uuringus käsitletakse ginkgoliidi B, mis on taimne koostisosa, mis ekstraheeritakse hõlmikpuu puulehtedest. Leiti, et koostisosa aitab noorelt ära hoida migreeni ja peavalusid (31). Teises uuringus leiti, et ginkgoliidi B võib kasutada auraga migreeni (nägemishäiretega migreeni) raskuse ja sageduse vähendamiseks (32).

9. Võib parandada astma ja KOK-i sümptomeid

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.

Expert’s Answers For Readers’ Questions

Should I take ginkgo at night?

Ginkgo can stimulate your brain and keep you awake the whole night. Do not take it before sleep.

Does Ginkgo biloba cause liver damage?

Ginkgo has not been linked to liver damage. In fact, it is sometimes used to treat certain liver ailments (50).

Does Ginkgo biloba raise blood pressure?

Puuduvad uuringud, mis väidaksid, et hõlmikpuu võib vererõhku tõsta. Kuigi hõlmikpuu omab veresooni laiendavaid omadusi, pole selge, kas see võib vererõhku vähendada.
