Useful Plants At The Farm- Galangal or Alpinia Galanga / Greater Galanga
The Greater Galanga or lengkuas is a ginger originally from Malaysia and Indonesia. It is used in Thai, Malay, Nyonya and Indonesian cuisine.
It is active against gram-positive and gram-negative bacteria.
In our farm, we have found it to be effective against mycoplasma sp. infection in the chickens. In combination with garlic and at the appropriate dosage it is effective against chronic infections.
We now use lengkuas as a weekly preventive for the chickens
At our farm, we grow the lengkuas wild in our Food Forest. It requires no maintenance and provides free medicine for our animals and even our workers.
Here’s more information about lengkuas:

Useful Plants At The Farm- Derris elliptica or Tuba
Tuba root has long been used by the ‘Orang Asli’ to fish, as it is a piscicide.
As we can see from the pictures, the plant has arresting flowers.
It is a creeping and climbing vine.
It is a wasteful method of fishing as all fish, big or small are wiped out within minutes. Thankfully, very few ‘Orang Asli’ are using tuba roots nowadays and in fact, some do not even know how to identify it.
The root of the tuba.
In the farm we grow it for use as an insecticide. It is the only local plant that we know of, that’s truely insecticidal. The rest are repellents. For many years, organic standards permitted the use of rotenone, the active ingredient in tuba root against insects. That has now been withdrawn.
Pounding the root.
We do not use tuba on vegetables or fruits, but on roots and trunks of non-fruiting trees and ornamentals that are attacked by tough borers etc. The withdrawal of its use in organic farms is because of concern over its safety after scientists injected the active ingredient, rotenone, into the blood stream of rats and which resulted in Parkinson’s-like symptoms in the rats.
The pounded root will be squeezed in water to make an aqueous extract of the active ingredient, rotenone.
The milky aqueous extract ready for use.
Quote from Wikipedia, “In 2000 it was reported that injecting rotenone into rats causes symptoms of Parkinson's disease to develop. Rotenone was continuously applied over a period of five weeks, mixed with DMSO and PEG to enhance tissue penetration, and injected into the jugular vein.[12] “ . Citation [12] here refers to : Caboni P, Sherer T, Zhang N, Taylor G, Na H, Greenamyre J, Casida J (2004). "Rotenone, deguelin, their metabolites, and the rat model of Parkinson's disease". Chem Res Toxicol 17 (11): 1540–8.
One would think that would be expected injecting toxic stuff into the bloodstream. Anyway, as an organic farmer, it is better to be on the safe side and cease from using tuba on edibles. The tuba extract does not remain in the environment and is totally detoxifed in 6 to 7 days, being degraded by sunlight.
In the farm, though rarely used, it is nonetheless a useful plant to have.

'Miraculous' Plants at the Farm

The young green unripe limau nipis,(Citrus Aurantifolia), or key lime, is the most aromatic fruit you will ever taste. We kid you not!!
But you need to first eat one of the berries from this bush - the Miracle Berry bush.
Otherwise the extreme sourness of the limau will shut down all your other senses and you will not be able to experience the aroma. After you chew on the berry,
the sourness of the limau is ‘smothered’ by sweetness. The limau becomes so delicious you want to finish off the whole fruit and you have to remind yourself what’s happening to avoid a major tummy upset later on.

The Miracle Berry Bush
The miracle berry is a bush from West Africa (Synsepalum dulcificum or Richadella dulcifica).
The active ingredient is called Miraculin, which in itself is not sweet, but the tongue, once exposed to miraculin, perceives sour foods such as citrus as sweet for up to a couple of hours afterwards.
If you chew on the fruit of the lemba or curculi latifolia, plain water and any sour drink will taste sweet. The lemba is found in wet areas of the jungle and we can find them in the jungle next to our farm. The leaves can be used to make ropes and for wrapping things. 
There's a patent in the USA (Patent 5378489 ) for the use of the active ingredient, curculin, as a form of sweetener by a team of Japanese scientists.
Don't you think we Malaysians should be ashamed of ourselves for not recognising the value of plants that's growing literally right outside our doorsteps?

This is a plant from Central America, now endemic in Malaysia. It is an inconspicuous and not particularly pretty small tree. You will see it by the road side growing wild. It is known as 'pokok pagar' locally. In our farm, it serves multiple functions.
