This is a relatively new drink in the market. Drinho has been selling Ho Yan Hor drinks in packet form. They come in two flavours, one is Sour Plum (aka Buah Asam, in green packaging) and the other is Luo Han Guo (aka longan??) in the brown packaging as shown below.
250ml each.
I know a lot of people are wary about packet drinks since they are usually very sweet with some commercialized chemical taste, but this is pretty authentic. I really like the flavour of this, it tastes almost like the kind of luo han guo you get at chinese food courts.
The REAL Ho Yan Hor herbal tea is extremely bitter. I mean really bitter. It comes in what looks like a really big tea bag and is a lil pricey. I've tried it before and I can understand why people put asam inside. Makes it easier to swallow! But one of the main benefits of the original Ho Yan Hor is that it is cooling. I experience heatiness (yit hei) quite often and I eat/drink as many cooling things as I can.
Do I feel 'cooler' after drinking this? I'm not 100% sure really. It could be psychological. Like I give you a glass of water and I tell you it's gonna make your fever go away. If you believe it, it'll probably work, lol :)
I'm not saying that this drink doesn't help, but I like it because of the flavour. The Asam flavour version is pretty authentic too. My friend who's never tried Ho Yan Hor made a weird face when I let her try it.. hehehe.
Cooling or not, I will buy it. Retails for about RM7.22 for a pack of 6 if I am not mistaken. It may be more expensive than buying the real luo han guo from chinese tea stalls, but you're paying for convenience and mobility.
