There is no tea in yellow version, just go to the top floor of the mart in Celadon city and buy water and give it to one of the guards.
Buy fresh water and give it to the guard

you have to go and get the tea from the old lady in celedon otherwise he will not let you pass the good thing is that when u give tea to on guard, the rest will also let you pass
If your playing the original red version you need to just hand the water to the guard, if your playing firered you need to get Tea from an old lady in the celadon mansion and give that to the guard.
You go to celadon city and go to the 2nd or third building you see at the top of ur gameboy. Go inside and there will be an old lady. talk to her and she will give you the tea. trust me. I have PKMN Red,Blue,Yellow,Emerald,sapphire,ruby,leafgreen,and firered.
Go to Saffron City by giving the guard the tea you obtained from the old lady in the mansion. Then go into Silph Co.
get the hot tea from the old lady in the same building you get eevee it at the 4th badge
Yellow tea is made similar to green tea, just oxidized somewhat longer than green tea, but shorter than black and oolong tea. This means that the health benefits of yellow tea are similar to those of green tea. Green tea is known for its ability to help control appetite and help with weight loss. So since yellow tea is similar to green tea I believe it is safe to assume that yes it could possibly help slim you down if you drank enough of it.
