Apa itu Jelatang yang Menyengat?
Jelatang yang menyengat (Urtica dioica) telah menjadi jamu pokok sejak zaman kuno (2). Ia mempunyai profil biokimia eksotik. Ia tumbuh di iklim sederhana hingga sederhana di seluruh dunia - terutamanya di tempat yang mempunyai banyak kelembapan. Anda boleh menjumpai spesies jelatang tertentu di hutan, di tepi sungai atau sungai, dan di tepi jalan.
Nama saintifiknya Urtica dioica berasal dari kata Latin uro, yang bermaksud "terbakar," kerana daunnya dapat menyebabkan sensasi terbakar sementara ketika bersentuhan. Tumbuhan ini (atau rumpai) berasal dari Mexico, Itali, Nepal, India, China, Rusia, Belanda, Amerika Utara, dan bahagian Afrika. Spesies jelatang tertentu, terutama jelatang yang menyengat, mempunyai rambut di daun dan bahagian udara. Sebilangan ini juga! Oleh itu, nama (1).
Daunnya ditutup rapat dengan rambut yang menyengat, yang melepaskan racun yang berpotensi menyakitkan (1).
Apabila kulit manusia bersentuhan dengan daun atau batang jelatang, ia cepat tumbuh tompok kemerahan yang gatal dan terbakar. Rambut atau trikom tumbuhan secara semula jadi dirancang untuk melindungi tanaman daripada serangga.
Walau bagaimanapun, pengambilan ramuan ajaib ini setelah diproses adalah selamat. Bahagian berikut adalah mengenai faedah daun jelatang yang menyengat. Mula menatal!
Apakah Manfaat Kesihatan Jelatang yang Menyengat?
1. Boleh Meningkatkan Pertumbuhan dan Kekuatan Rambut
Ubat tradisional menggunakan spesies Urtica untuk merangsang pertumbuhan rambut. Satu kajian menyelidiki sifat jelatang yang menyengat (Urtica dioica) ini dengan gabungan ekstrak herba. Penyediaan herba ini meningkatkan percambahan sel papilla kulit manusia (3).
Β-sitosterol dalam menyengat jelatang memicu pembentukan saluran darah baru (angiogenesis). Ia mendorong sintesis faktor pertumbuhan endotel vaskular (VEGF) dan menyokong pertumbuhan rambut baru (3).
Daun dan akar jelatang menyengat mengatur aktiviti hormon seks dan substratnya. Mereka membantu mengawal keguguran rambut (alopecia) pada lelaki dan wanita dengan ketidakseimbangan hormon (4).
2. Boleh Merawat Demam Hay, Asma, dan Alahan
Demam Hay atau rinitis alergi disebabkan oleh debunga, tungau debu, jamur, spora kulat, lipas, dan bulu. Sebab-sebab lain termasuk kepekaan makanan, penyakit metabolik, dan ubat-ubatan tertentu. Gejalanya termasuk bersin, hidung tersumbat, gatal-gatal, lakrimasi (terkoyak berterusan), sakit kepala, mulut kering, mengantuk, keletihan, dan aritmia jantung (5).
Di sinilah ubat alternatif dapat menyelamatkan (5), (6). Jelatang yang menyengat (Urtica dioica) mengandungi nicotinamide, synephrine, dan osthole, dengan sifat anti-radang dan anti-alergen yang kuat.
Fitokimia ini menunjukkan aktiviti antagonis terhadap reseptor histamin pro-radang, menyekat pengeluaran dan pembebasan histamin (5). Mereka juga mengganggu aktiviti sel pro-radang, utusan kimia, dan gen pengawal (5).
Pengamal kesihatan harus meneliti penggunaan ubat alternatif untuk merawat gangguan akut dan kronik seperti asma, alergi saluran pernafasan, dan lain-lain sebagai alternatif ubat biasa (6).
3. Boleh Membantu Menguruskan Masalah Prostat
Pertumbuhan kelenjar prostat yang berlebihan (hiperplasia prostat jinak) meningkatkan tekanan pada uretra. Ini melumpuhkan sistem kencing dan menyebabkan beberapa gangguan kronik dengan penuaan (7).
Dalam kajian tikus, jelatang menyengat menunjukkan peningkatan dalam masalah prostat. Ekstrak akar jelatang menghalang aromatase, enzim yang mengubah testosteron menjadi estrogen. Estrogen berkait rapat dengan gangguan prostat (7).
Kajian lain menunjukkan sifat antiproliferatif akar jelatang pada sel barah manusia. Ekstrak alkohol 20% dari akar jelatang yang menyengat mengurangkan pertumbuhan sel epitel prostat barah selama tujuh hari (8).
4. Boleh Mengurangkan Keradangan
Ekstrak jelatang yang menyengat mengandungi bahan anti-radang yang dapat menekan beberapa sitokin pada penyakit sendi radang (9).
According to another study, applying stinging nettle leaf appears to relieve osteoarthritic pain (10). Stinging nettle reduced levels of multiple inflammatory hormones by interfering with their production (11).
However, more research and human studies are required to recommend nettle as an anti-inflammatory treatment.
5. May Lower Blood Pressure
Stinging nettle was traditionally used to treat high blood pressure (12). Stinging nettle extract was found to possess antihypertensive effects.
It may help lower blood pressure by allowing blood vessels to relax and reducing the force of the heart’s contractions. More human studies are needed to confirm these effects.
6. May Aid Blood Sugar Control
Nettle has shown some promising effects on blood glucose levels. Traditional medicine uses nettle leaves to treat diabetes mellitus due to their anti-hyperglycemic properties (13).
However, more research on humans is needed to establish the safety and efficacy of nettle leaves in controlling blood sugar levels.
7. May Monitor Heart And Liver Health
In a 2018 rat study, the administration of 150 mg/kg/day stinging nettle extract for a month improved the blood lipid profile. The nettle extract worked far better than its commercial synthetic drug counterpart (14).
Nettle extract boosts the antioxidant machinery in the body, thereby preventing (and ending) lipid peroxidation. A balanced lipid profile and healthy liver reduce the risk of hypercholesterolemia-induced diseases (15).
Hypercholesterolemia is linked to atherosclerosis and other inflammatory diseases. Nettle leaf helps prevent atherosclerosis and hypertension, as per rat studies. It is, hence, a potent hepato- and cardioprotective dietary additive (16).
8. May Help Treat Menstrual Health, PCOS, And Fertility Concerns
Around 10%-15% of women of reproductive age experience oligomenorrhea and 3%-4% of them have amenorrhea.
Oligomenorrhea and amenorrhea are changes in regular menstrual cycles that cause long menstrual cycles and the absence of menstruation, respectively. While hormone replacement therapy is the most common remedy, herbal medicine is proving to be effective in such cases (17).
Herbal extracts of nettle, peppermint, onion, and nigella showed a positive effect on polycystic ovary syndrome (PCOS). They could control menstrual bleeding, ameliorate menstrual irregularities, balance hyperandrogenism, and promote fertility (17).
These herbs possess phytochemicals, including flavonoids, phenols, phytosterols, and terpenoids, that can mimic the natural hormonal function and restrict bleeding. That is why nettle plant parts can enhance follicle maturation, reduce coagulation factors, relax uterine muscles, and facilitate uterine recovery (17), (18).
9. Can Accelerate Wound Healing
Wound healing could get prolonged in the presence of free radicals and several physiological stresses. The delay might affect one or all steps of wound contraction, recovery of epidermal cells (reepithelialization), and restoration of blood supply (neovascularization) (18).
Using plant medicine for healing wounds is an ancient remedy. Several flowering plants like stinging nettle have been lauded for their vulnerary and antioxidant properties.
The nettle leaf has an antihemorrhagic effect because of its flavonoids, minerals, vitamins, and fatty acid content (18).
Using stinging nettle extract on wounds would reduce the bleeding time and promote blood clotting. It also eliminates pathogens, traps the pro-inflammatory free radicals, and reduces the average healing time in rat models (18).
In short, the leaf, root, and other parts of the stinging nettle have powerful antioxidant, vulnerary, antihemorrhagic, anti-inflammatory, anti-atherosclerotic, anti-hypercholesterolemic, cardioprotective, hepatoprotective, anti-allergic, and anti-diuretic properties.
Shouldn’t there be something in the nettle plant parts that impart(s) these properties?
Absolutely! Learn more about them in the following section.

These compounds can cause burning and rashes. Researchers found that nettle roots might cause GI tract disturbances, profuse sweating, and allergies in some individuals. Freshly plucked nettle leaves might cause localized stinging, rash, itching, and tongue edema (21). But as they act as an emmenagogue, they may possess uterine-stimulant properties.
