Turmeric (Luyang dilaw) Curcuma longa 
 Medicine-and-Spice
Luyang dilaw has outstanding medicinal properties that are a potential cure to many ailments and diseases associated with our postmodern living. 

Dr Abe V Rotor 

You may miss the plant on the farm, roadside, pasture, or the garden.  It is because it is unassuming in its vegetative stage - appearing like lily, baston de San Jose, lobster's claw, camia or any of its relatives under Family Zingiberaceae or ginger family.

But no one would miss in its flowing stage, this plant universally known as tumeric,  Its flowers are typical of ginger species led by the popular Zingiber officinale or luya, no kitchen is without it.  

Luyang dilaw is a leafy plant, 1 to 1.5 meters tall, with 5 to 6 leaves. Rhizomes are bright yellow inside, thick and cylindrical. Leaf blade is green, oblong, 30 to 45 centimeters long and 10 to 20 centimeters wide. Petiole is as long as the blade. Peduncle is 15 centimeters or more in length, borne within the tuft of leaves. Spikes are 10 to 20 centimeters in length and about 5 centimeters in diameter. Floral bracts are pale green, ovate, 3 to 4 centimeters long, the comabracts tinged with pink. Flowers are pale yellow to pink, as long as the bracts. Fruits are capsules.

Luyang dilaw is pantropic, native of India, Its rhizomes are contain flavonoid curcumin (diferuloylmethane) and various volatile oils, including tumerone, atlantone, and zingiberone. It contain volatile oil (3-5%), tumerol (alcohol), d-alpha phellandrene, carvone, camphor, curcumone; fat, 3%; starch (30%); resin; curcumin (yellow orange pigment). It is a good source of phosphorus and iron.

As one who grew up on the farm, luyang dilaw is a familiar wild plant which old folk would gather for spice like the local luya. My Auntie Yaya, Basang would dig up a hill even if the rhizomes are still young and small, and would crush them as poultice for minor wounds and insect bites. A decoction would expel bad air, and loosen breathing if you have colds or flu. Little did I know about this annual plant. It aestivates in summer, awaking at the first rain in May, profusely growing to overcome weeds around. It would bloom shortly, then dries up leaving its rhizomes beneath the ground - if not harvested -  only to germinate again the next monsoon season.  

Here is a summary of some distinct characteristics of luyang dilaw, largely from researches I conducted in the university and from the Internet. Thanks to Philippine Medicinal Plants, and Alternative Medicine. Special thanks to the late Dr Eduardo Quisumbing, author of Medicinal Plants of the Philippines, who was then my professor in botany in the early sixties.
