Dandelions: potensi faedah, dos, dan kesan sampingan

Dandelions secara saintifik disebut Taraxacum officinale . Mereka bukan hanya rumpai yang menjengkelkan yang menonjol di halaman belakang rumah anda. Dalam perubatan tradisional, ini diketahui telah digunakan untuk sifat perubatan mereka.

Kajian haiwan menunjukkan bahawa dandelion dapat membantu dalam rawatan diabetes (1). Lebih banyak penyelidikan menjelaskan kemungkinan manfaat dandelion untuk kesihatan, termasuk memerangi keradangan dan barah.

Di sini, kami akan meneroka pelbagai cara bunga ini dapat membantu meningkatkan kesihatan dan kesejahteraan anda.

Apa Manfaat Kesihatan Dandelion yang Berpotensi?

Sebatian bioaktif dalam dandelion dapat membantu melawan keradangan dan juga barah. Mereka juga dapat membantu menurunkan kadar gula dalam darah. Walaupun kandungan kalsium dan vitamin K mereka dapat menguatkan tulang, kandungan zat besi mereka dapat membantu mencegah anemia.

1. Boleh Membantu Melawan Keradangan

Sel yang dirawat dengan sebatian dandelion didapati mempunyai tahap keradangan yang lebih rendah. Polisakarida dari dandelion mempunyai sifat anti-radang dan anti-oksidatif yang memainkan peranan yang menjanjikan dalam hal ini (2).

Dandelion berfungsi dengan mengurangkan pengeluaran sitokin pro-inflamasi, yang merupakan sebatian yang biasanya terlibat dalam keradangan tubuh (3).

Dalam kajian lain yang melibatkan tikus dengan radang paru-paru, pengenalan dandelion (Taraxacum mongolicum, tumbuh di China) didapati memperbaiki keadaan (4).

2. Boleh Mengurangkan Risiko Kanser

Kajian yang dilakukan pada akar dandelion (dan ekstrak serai) mendapati bahawa ia mempunyai potensi anti-barah. Akarnya ditemukan untuk mendorong apoptosis (kematian sel barah) dan meningkatkan kesan kemoterapi. Kajian ini dilakukan pada sel barah prostat (5).

Ekstrak akar Dandelion boleh menjadi alternatif anti-kanser yang tidak beracun dan berkesan. Ia dapat memicu kematian sel kanser yang diprogram dalam model barah kolorektal. Kerumitan molekul (parameter tertentu yang terlibat dalam penemuan ubat) ekstrak akar boleh bertanggungjawab untuk aktiviti anti-barah ini (6).

Ekstrak akar Dandelion juga didapati dapat mencegah barah hati (7). Kesan serupa juga dilihat pada barah pankreas (8).

Walaupun penemuan ini menggembirakan, lebih banyak penyelidikan diperlukan untuk memahami dan menentukan bagaimana dandelion dapat mencegah dan merawat barah pada manusia.

3. Boleh Membantu Rawatan Diabetes

Asid chicoric dan chlorogenic di dandelion memiliki potensi besar sebagai nutraseutikal dan farmaseutikal anti-diabetes untuk mengawal diabetes. Asid mengandungi sebatian fenolik yang dapat meningkatkan kesan anti-diabetes bunga (1).

Dalam satu kajian, kedua-dua daun dandelion dan akarnya didapati mempunyai kesan terapeutik yang serupa pada individu yang menghidap diabetes. Ini dapat meningkatkan kesihatan dan kesejahteraan jangka panjang pesakit (9). Walau bagaimanapun, kesan jangka panjang penggunaan dandelion perlu dikaji.

Sebatian bioaktif lain dalam dandelion yang menawarkan faedah anti-diabetes termasuk fenol, flavonoid, asid fenolik, dan triterpen. Akar dandelion mengandungi inulin, yang mengandungi karbohidrat kompleks. Ini membantu menormalkan tahap gula dalam darah (1).

4. Boleh Menggalakkan Kesihatan Jantung

Tikus yang dirawat dengan ekstrak dandelion menunjukkan penurunan dramatis dalam kadar trigliserida dan kolesterol. Ketika tikus diberi makanan berlemak tinggi ditambah dengan ekstrak, pengurangan lipid hepatik berkurang diperhatikan (10).

Penemuan serupa diperhatikan dalam kajian arnab. Pada arnab yang diberi makanan tinggi lemak, pengenalan akar dandelion meningkatkan status antioksidan dan menurunkan kadar kolesterol serum. Akarnya juga mengatasi tekanan oksidatif dan boleh meningkatkan kesihatan jantung (11).

Dandelion juga dapat meningkatkan kesihatan jantung dengan menurunkan tahap tekanan darah. Tumbuhan ini mengandungi kalium (12). Kajian menunjukkan bahawa kalium diet biasa dapat membantu menurunkan kadar tekanan darah (13).

5. Boleh Membantu Mengurangkan Berat Badan

Dandelion didapati mempunyai kesan yang serupa dengan ubat penurunan berat badan yang popular (Orlistat), yang berfungsi dengan menghalang lipase pankreas. Lipase pankreas adalah enzim yang dilepaskan semasa pencernaan yang membantu pemecahan lemak. Menghambat enzim ini dapat mengubah cara penyerapan lemak di dalam badan, yang dapat membantu menurunkan berat badan (14). Walau bagaimanapun, kajian lanjutan diperlukan untuk menjelaskan kesan anti-obesiti dandelion pada manusia.

Dandelion adalah ramuan pahit. Kajian menunjukkan bahawa ramuan pahit, jika diambil sebagai teh sebelum makan, dapat merangsang rembesan gastrik dan mendorong kolesterol dan pemecahan lemak. Dengan cara ini, mereka dapat melengkapkan usaha menurunkan berat badan anda (15).

6. Boleh Menggalakkan Kesihatan Tulang

Dandelion hijau adalah sumber vitamin K dan kalsium yang baik (12). Kedua-dua nutrien ini dikaitkan dengan kesihatan tulang.

Vitamin K diketahui dapat meningkatkan pembentukan tulang. Ia juga dapat mengatur keseimbangan kalsium dan metabolisme tulang. Selain meningkatkan kepadatan mineral tulang, vitamin K juga mengurangkan kadar patah tulang (16).

Pengambilan kalsium juga mempengaruhi kesihatan tulang dengan cara yang positif. Ia memainkan peranan penting dalam mencegah kehilangan tulang dan patah tulang (17).

Sebatian dalam dandelion mengandung prebiotik, yang didapati dapat meningkatkan penyerapan kalsium. Dengan cara ini, mereka juga berperanan dalam kesihatan tulang (18).

7. Boleh Meningkatkan Kesihatan Hati

Akar Dandelion dapat meningkatkan kesihatan hati dengan pelbagai cara. Dalam satu kajian, ia dapat mengurangkan penyakit hati berlemak bukan alkohol yang disebabkan oleh diet tinggi lemak dan juga mengurangkan tekanan oksidatif yang disebabkan oleh alkohol (19).

Beberapa penyelidikan juga menunjukkan bahawa dandelion dapat mendorong pemulihan dari kecederaan hati (20).

8. Boleh Meningkatkan Kekebalan

The flavonoid contents of dandelion may have a major impact on the human immune system. It contains short-chain fatty acids, which were found to boost immune function and prevent infectious diseases in weaned pigs (21).

Dandelion also may nourish the blood cells in the body. Mice studies show it can help achieve normal red blood cells and white blood cells balance. This way, it may boost the immune system (22).

9. May Prevent Anemia

There is less information available in this aspect. Some research states that dandelion can help prevent anemia as it contains iron (23). One cup of chopped dandelion (55 g) contains about 2 mg of iron (12).

10. May Prevent Water Retention In Kidneys

The diuretic properties of dandelion can help here. Its high potassium content makes dandelion a good diuretic (24).

In a study, intake of dandelion increased the urinary frequency in subjects over a period of 5 hours (25). Hence, this plant shows promise as a diuretic in humans and may help prevent water retention in kidneys. However, if you have kidney disease, consult your doctor before using dandelion.

11. May Boost Skin Health

Studies show that dandelion extracts can protect the skin from UVB damage. They exhibited protective effects against photoaging (26).

In folk medicine, dandelion (especially the sap of the plant) was believed to be used to treat warts and eczema, among other skin disorders (27).

Some evidence also states that the sap of dandelion may be used to combat acne (28). However, more research is warranted in this regard.

These are the ways dandelion can make your life better. Though we know a few of the nutrients present in this plant, well, there is a lot more. In the following section, we will take a detailed look at dandelion’s nutrition profile.

That’s an impressive nutritional profile, isn’t it? Including dandelions in your diet is quite easy. Up next, we will discuss a few simple ways to do just that.

How To Consume Dandelions

• The simplest way to consume dandelions is to include them in a salad. Just toss a few dandelion greens into your evening vegetable salad.
• Sauteéd dandelions are another good option. Cooking dandelions removes their bitterness. You can boil the greens for about 5 minutes and then transfer them to a pan with garlic and hot olive oil. Sauté for 3 to 5 minutes. Eat as it is.
• You can also use dandelion flower petals in your preparations. You can add the petals to your bakery items like muffins, cookies, or even plain bread.

The most popular way of enjoying the goodness of dandelion is in the form of tea. But how do you make it?

How To Make Dandelion Tea

The process is simple.

1. Throw the dandelion roots into a food processor and process.
2. Dry them at 250o F in an oven until they are completely dry.
3. Roast in the oven at 350o F until they turn brown.
4. Add the roots to water in a pan and bring to a boil. You can add 2 tablespoons of the root for every 16 oz of water.
5. Simmer for 20 minutes.
6. Strain the liquid and drink.

What Is The Ideal Dosage Of Dandelions?

The American Botanical Council recommends the following doses (29):

• For the powdered root, the dosage is 3 to 4 grams, thrice daily.
• If you are taking a decoction, boil 3 to 4 grams of powdered root in 150 ml of water.
• In case of an infusion, you can steep 1 tablespoon of cut root in 150 ml of water.
• If you are having a tincture, stick to 10 to 15 drops, thrice daily.

You can get the supplement here.

Before you start making dandelion a regular part of your diet, you need to be aware of its side effects.

Do Dandelions Have Any Side Effects?

• May Cause Allergies

Dandelions may cause allergic contact dermatitis. This can be attributed to the presence of compounds called sesquiterpene lactones, which are irritants. The symptoms of these allergies include dry and itchy eczema-like reactions (31).

• May Interfere With Blood Thinners

Dandelion is rich in vitamin K, which aids blood clotting. Dandelion may interfere with blood thinners like Warfarin (32).

• May Cause Kidney Failure In Susceptible Individuals

There is less research on this. However, a herbal remedy containing dandelion as one of the primary ingredients caused renal failure (33). If you have kidney issues, please avoid dandelion and check with your doctor.

There is no information on the safety of dandelion during pregnancy and breastfeeding. Hence, consult your doctor in this regard.

Conclusion

Though they seem like simple weeds, dandelions may have several benefits. However, more research is needed to establish these benefits for humans. Also, be aware of the possible side effects and consult your healthcare provider before including dandelion or its supplements in your diet.
