Although it need further research, people sure that white turmeric (curcuma zeodaria/Zedoariae Rhizoma) able to block cancer cell growth. In some cases, and some literature have approved it. If you interest to consume it, don’t be deceived from other turmeric variant that is look like cucrcuma zedoaria, which its power is not afficacious as white turmeric to against cancer disease.
People can be deceived, think that curcuma (Curcuma xanthorrhiza Roburgh) as turmeric. Because in some places curcuma plant has been named as white tumeric (cucrcuma zedoaria). In indonesia its named temu-lawak. Its rhizome like of turmeric (curcuma domestica or curcuma longa), but little bigger. If tumeric having a saffron color, curcuma being colored yellow and tending to whitish after it being chopped and dried up. The other curcuma that being called wrongly as white tumeric is temu mangga (curcuma mangga). usually many people use it for fever condition (antipiretika), weight loose, irritancy or asphyxia. And also frequently being used to to tighten woman vagina after puerperal/childbirth.
There are greater galingale (kaempferia galanga) species that is thought as turmeric, its name is temu-kunci (kaempferia angustifolia), that able to being used for anti-diarhea and anti-dysentery. And kunci-pepet tulen (Kaempheria rotunda) that usually being used as anti-inflammation, antipiretika and to arouse appetite.
So let us correct these terminology problems, that is complicated wrongly. The herb that we being discussed is temu-mangga (curcuma mangga) and its variant, white turmeric (Curcuma zedoaria). In herbal society it being used to treat several stomach problem. It turmeric has a whitish skin but you can find a pimple like a small potato around its root. ciri white tumeric that is useful to against cancer desease are: it has a whitish skin, its flesh colour is cream with manggo aromatic. Fragrance and it taste is not bitter.
Accordion to Dr. Retno S. Sudibyo, a researcher of PAU Bio tecnology UGM, we can eat its fresh root to get its expedience to against cancer. But don’t eat to much, because it can causes diarhea if you’re not resistant.
Both temu-mangga (curcuma mangga) and white turmeric(curcuma zeodaria) content of colorant yellow kurkumin (diarilheptanoid). The Encilopedia of Medical Plands book said that kurkumin has special quality as antioxidant and anti-inflammation. their antioxidant content is stronger than vitamin E while their anti-inflammation content is sronger than chemical hidrocortison/synthetic. The volatile oil component from cucrcuma zedoaria rimpangcontent of: Guaian derifatives (Kurkumol, Kurkumenol, Isokurkumenol, Prokurkumenol, Kurkurnadiol), Germakran derivatives (Kurdion, Dehidrokurdion); Seskuiterpen furanoid with eudesman skeleton (Kurkolon). Germakran skeleton (Furanodienon, Isofuranodienon, Zederon, Furanodien, Furanogermenon); Eleman skeleton(Kurserenon identical with edoaron, Epikurserenon, Isofurano germakren); Asam-4-metoksi sinamat (having the character of fungiStatic). From other research, there are kurkumanolid A, kurleumanolid B, and kurkumenon found in cucrcuma zedoaria.
American Institute of cancer report that cancer can be prevented using turmeric. the antioxidant inside cucrcuma zedoaria be functioning to prevent deoksiribonuklead acid (gene composer) from damage. The gene damage is one of a cancer appearance factors.
Kurkumin with feruloyl and 4-hydroxycinnmoyl are a anti inflammation composite that is contained in turmeric rhizome. kurkumin component very beneficial to against cancer, protect gene from damage and anti-inflammation contemporaneously. Because in cancer disease case inflammation is always happen.
Dr. Retno S. Sudibyo research (published by Tempo 30 mey 1999), give some results that curcuma mangga content of protein toxin, sejenis Ribosome in Activating protein (R.I.P). This is a sejenis that has ability to deactivated ribosom, so that protein synthesis inside cell being hampered. Its easily for this protein to penetrate cancer cell then to penetrate the healthy cell. It causes cancer cell can not proliferate because cancer cell has age limit. At last it will be vanished automatically.
So the conclutions are:
