Why can't I add the regular potion of healing to my inventory on my character sheet?  I only see listings for greater and higher...

Become a conjunction wizard 

No gold price on this page? Why make two pages for the same item?

Good idea i would love to see this 

feeding you a potion is their action, not yours.

PLEASE ADD PRICES!!!

No, when you are unconscious you can't drink. You'd need healing magic or become stable and take a long rest to recover 1hp, then you can drink the potion

Bababooey

exception: there are non-magical healing potions, and two kits that (herbal Kit) and (healer's kit) that are medical not magical, based on the medicine skill.

Agreed - it's their action to feed you, not your action to drink. I would clarify that you're still in order of initiative, too. If you rolled your death save already, you can't get up until next round. If the character that administered the potion was ahead of you in initiative order, you can get up on your turn and take an action in the same round as you were fed.

you could use the xanathars guide table to determine prices ? so

common - 1d6 + 1 x 10 GP

uncommmon - 1d6x100 GP

rare - 2d10 x 1000GP

very rare - 1d4 + 1 x 25,000GP

I hope this helps people 

Quote from AndrewDanger >>

If someone feeds a potion of healing to a teammate, who rolls the dice? The person who is receiving the potion or the person who administered it?

... Does it matter?

Quote from VancouverDave >>

So someone feeds you a potion of healing during combat while you were unconscious ... is ‘drinking’ your action for this round? Or can you, in the same round, stand up (using half your movement) and take an action?

 no, its their action for that round

I've showy felt that 5e made magic super common.

This potion doesn't seem to show up under "Manage Inventory: Add Items" on either the character sheet or builder, for some reason.

Only the Greater, Superior, and Supreme versions (all more powerful than this) show...

Quote from Bossidious >>

For those who ran into this same issue: The common healing potion is the only healing potion that isn’t classified as a potion in your character sheet. Instead, it’s set under “Other gear”. Definitely a bug that they need to fix.

 Oh, this explains it!

regular is 50gp (stated in the PHB)

The DMG says magic item prices per rarity are:

Uncommon: 101-500 gp

Rare: 501-5 000 gp

Very Rare: 5 000-50 000 gp

It also states consumable items are priced half of normal ones, therefore the price should be 

For a greater healing pot: 50-250 gp 

For Superior: 250-2 500 gp

For Supreme: 2 500- 25 000 gp

Obviously you can alter this to be more balanced for your games if you like, this is just what the books say and how I'd interpret them.

Hope this helps (4 years later but still) 

A column perhaps containing some average prices would be a nice edition.

This may have been fixed since the initial question.  I couldn't find a regular healing potion to add either, but if you type in healing with potion filter on the standard healing potion will be there to add.

I found the potions to be... Too expensive? For the group I DM I do-

20Gp potion of healing

100Gp potion of greater healing

250Gp potion of superior healing

500Gp potion of supreme healing.

I then make the shops that can sell them more rare, yeah sure every town might have a couple stashed away in their local trading post (normally I roll 1d4 and this represents the number of healing potions and on a 4 it's one potion of greater healing)

But they can buy them in much greater numbers at potion shops alchemists or something similar
