ULAM RAJA

-




Scientific name: Cosmos caudatus

 Malay name: Ulam Raja


Facts:

  • Ulam raja is indigenous throughout Central and South America, as well as Asia and many tropical regions around the world.
  • It is popular in Malaysia, as Malaysian and Thai food will often serve this leafy green as a garnish or even as a salad ingredient.
  • Ulam Raja exhibits high anti-oxidant capacity and various medicinal properties, including anti-diabetic activity, anti-hypertensive properties, anti-inflammatory responses, bone-protective effect, and anti-microbial activity.


General uses:

1. Used for reducing blood pressure and bone loss.

2. Traditionally, C. caudatus has been used to boost blood circulation, to strengthen the bones, to reduce body heat, as an anti-ageing agent, and to treat infectious diseases.

3. C. caudatus has also been shown to reduce inflammation.


Pharmacological and Medicinal uses :

  • Anti-oxidant potential
C. caudatus exhibits high antioxidant activity. Studies have shown that 100 g of fresh C. caudatus contains approximately 2500 mg ascorbic acid equivalent anti-oxidant capacity (AEAC) compared to local fruits with AEAC index of less than 300 mg.
  • Anti-diabetic activity
A local study reported that the hexane extract of C. caudatus has high alpha-glucosidase inhibitory activity with low alpha-amylase inhibition. Thus, C. caudatus may be potentially useful in treating postprandial hyperglycemia in vitro.
  • Anti-hypertensive activity
In adrenaline-treated rats, both 500 mg/kg and 1000 mg/kg aqueous extracts of C. caudatus were shown to inhibit the increase of heartbeat frequency and stroke increase in stroke volume amplitude.
  • Anti-inflammatory activity
Methanol and aqueous C. caudatus extracts at a dose of 200 mg/kg have exhibited significant anti-inflammatory activity by suppressing mouse paw oedema induced by carrageenan. The result was comparable to that of the two Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), and a fungus (Candida albicans) by the disk diffusion method.

Scientific name:  Gardenia jasminoides  J.Ellis Malay name: Melur Facts: G. jasminoides  is indigenous in southern China, Japan, the Ryukyu Islands, and Taiwan, possibly also locally in Sri Lanka. It is widely cultivated in the tropics and subtropics, and sometimes naturalised. In Southeast Asia, it is commonly planted in gardens. G. jasminoides  is originally a species from temperate climates. In tropical areas, it grows well at altitudes of 400-1200 m. In the tropical lowlands, it flowers poorly or not at all. It thrives best on properly drained, but not too dry soils with pH 6-7, and it prefers sunny places. G. jasminoides  fruit was found to contain iridoid glucoside (e.g. gardoside and scandoside methyl ester), and caratenoids (e.g. crocetin and crocin). Traditional Use: G. jasminoides  is believed to be bitter and cold in character and has been used to disperse heat, purges fire, cools the blood, and removes toxins. The w...
