Penelitian Khasiat Ashitaba



Pulau Hachijo, Jepang; Asal Ashitaba
Ashitaba (seledri Jepang) adalah tanaman/sayuran hijau berasal dari Pulau Hachijo, Jepang yang dikenal sebagai rajanya sayuran, disebut juga tanaman “Malaikat” karena banyaknya manfaat sebagai obat dari beberapa penyakit berbahaya. Ashitaba dikenal juga sebagai “Harta Karun” dan “Raja Sayur Mayur”. Menurut sejarah orang Jepang Ashitaba merupakan tanaman untuk panjang umur yang dulu dicari-cari oleh kaisar pertama Cina dari Dinasti Chin. Pada masa-masa jaman edo, Hachi Jo Islan Ashitaba juga dikenal sebagai jamu-jamuan Umur Panjang. Karena daya hidupnya yang kuat, bila dipetik daunnya hari ini maka daun muda yang baru akan bertunas esok harinya, itulah sebabnya ia dijuluki tomorrow leaf
Di Indonesia, Ashitaba bisa tumbuh di daerah puncak atau yang berhawa dingin seperti di gunung Rinjani Lombok, Gunung Raung Banyuwangi Jawa Timur. Berdasarkan hasil penelitian dr. Okuyama dari Tokyo Meiji University of Pharmacy, ashitaba dapat mengobati :
a. penyakit hati,
b. kanker paru
c. kanker kulit.
d. glukoma,mata minus plus dan katarak




Hasil Penelitian Ilmiah Tentang Kandungan, Khasiat dan Manfaat Ashitaba Herbal
Berbagai riset ilmiah berhasil mengungkapkan tentang bermacam-macam keunggulan Ashitaba sebagai Herbal/Tanaman Obat (TO). Dalam salah satu abstrak penelitian misalnya, secara terang-terangan dinyatakan bahwa Ashitaba telah terbukti menunjukkan kemampuannya sebagai Antitumor, Antioksidan, Antidiabetes, dan daun segar serta bubuknya berguna sebagai makanan kesehatan (Angelica Keiskei has been shown to exhibit antitumor, antioxidant, and antidiabetic activities, and fresh leaves and dry powder are used for health food) (Lee HJ, Choi TW, Kim HJ, Nam D, Lee EH, Lee HJ, Shin EM, Jang HJ, Ahn KS, Shim BS, Choi SH, Sethi G, Ahn KS, 2010).

Selain itu, tidak sedikit penelitian ilmiah yang berhasil menemukan bukti yang meyakinkan bahwa Ashitaba juga berfungsi untuk Antihipertensi dan Antistroke serta Antiinflamasi, bahkan Antibakteri. Semua keunggulan tersebut merupakan fakta-fakta ilmiah bahwa Ashitaba mempunyai kemampuan Antiaging yang sangat tinggi.
Ashitaba Antikanker
Riset ilmiah yang memperkuat bahwa Ashitaba bersifat Antikankeradalah sebagai berikut:
  1. Toshihiro Akihisa, Takashi Kikuchi, Hisashi Nagai, Koichi Ishii, Keiichi Tabata and Takashi Suzuki,“4- Hydroxyderricin fromAngelica keiskei Roots Induces Caspase-dependent Apoptotic Cell Death in HL60 Human Leukemia Cells”, Journal of Oleo Science,College of Science and Technology, Nihon University, Vol. 60 2011, No. 2 71-77.
    Kesimpulan: 4-Hydroxyderricin may therefore hold promise as an effective antitumor agent.
  2. Shinsaku Takaoka, Hiroshige hibasami, Kazuya Ogasawara & Nami Imai, “Chalcones from Angelica Keiskei Induce Apotosis in stomach Cancer Cells”, Journal of herbs, Spices & Medicinal Plantss, Vol. 14, 2008.
    Kesimpulan: These findings suggest that growth inhibition by xanthoangelol and 4-hydroxyderricin result from the induction of apoptosis by these Chalcones.
  3. DR. Shoji Shibata, “Antitumorgenic Chalcones”, Shibata Laboratory of Natural Medicinal Material, Minophagen Pharmaceutical, Tokyo Japan, 2010.
    Kesimpulan: It is possible that this compound and other structurally related Chalcones may be developed as effective agents for cancer prevention.
