For many who survived devastating Typhoon Haiyan the worst may still be ahead as victims cope with extreme hunger, contaminated water and infections.
Doctors said diarrhea is a daily problem, leading to potentially deadly dehydration.
That's why Alex Huang plans to fly to the Philippines Saturday.
Huang is the CEO of LiveLeaf in San Carlos, which makes an anti-diarheal product. He plans to bring suitcases full of the plant-based product.
"We're hoping to get several thousands, tens of thousands of doses to health workers there to give the anti-diarheal product to them and get them back to work," he said.

Huang said one dose can stop symptoms in just a few hours. The product has helped people in the aftermath of the 2010 earthquake in Haiti.

Those injured in the typhoon may also soon receive medical attention from Dr. Enoch Choi's group, Jordan International Aid.
The Redwood City urgent care doctor plans to send a team of about a 100 doctors and nurses from the Bay Area to provide medical care.
"What we always find is there is an overwhelming need and we are there to provide care where patients can't get care," Choi said.
