Sunstillshines, hi dear, actually I've been taking chinese herbs from a doctor in Toa Payoh since last Sept, problem is the medicine needs to be brewed daily... the herbs are adjusted to your body by this physician, it is actually pretty 'heaty' she told me, but as my body is very 'cold' i can drink that without falling sick at all, only feels more warm thereafter and body can tahan aircon after taking it for a month... prior to that i usually freeze whenever i enter air conditioned places... thats the only one i does religiously, i dont know if it is the one that helps, cos the rest like longan drink/ dr zou/ egg whites etc, i only took it after i embarked on my ivf in april... nothing at all before that just the herbs from this physician in Toa Payoh... if u dont mind exploring u can try, cos i've asked other medical halls with the prescription she gave me, all of them told me the prescription is all the 'heaty' herbs to regulate blood circulation so it increases the flow in the body, this can help those people whom are always 'cold'.... our womb especially is 'cold' by nature...
