Indanao,
I noticed in looking at those charts that June , July, and August had temperature slightly below 45 degrees and that would be enough chill for ginseng to break dormancy, I think? If the area you are wanting to grow ginseng in the Philippines has temperatures close to that, it might work. I thought the climate was more tropical though. The chart that Latt linked shows temperatures higher than that even at high altitudes. They are growing another plant there that is called ginseng, so don't confuse it with Panax Quinquefolius. If you try this, I would start very small and see what results you get.
