On Licorice


Recommended Posts

I find the effects of licorice very interesting.

WIthin a minute of me drinking its tea I get immediate benefit for all my POTS symptoms and notice the veins in my hands become more visible rather than less which is interesting.

It is often reported that its benefit comes purely from its sodium loading enhancing properties via psuedoaldosteronism - promoting volume expansion.

However, the effects i get from it are always acute and always straight away so I decided to look at alternative actions:

Reduces the expression of ROS superoxide free radicals and inductible (immune system) nitric oxide:

anti inflammation - inhibiting prostaglandin D2 and Cox-2:

Apparently INCREASES nitric oxide production in endothelial cells:

Or does it REDUCE endothelial nitric oxide (eNOS) and NAPHD related oxidisive stress?:

Reduces levels of angiotensin II

I have wondered why you are such a proponent of licorice. I have tried it in many forms, tea, dry root herb, and of course candy. I have not noticed any immediate improvements or downsides like you have and wonder have I just been missing them? The clinical evidence you shared makes me want to analyze more specifically. I have elevated Prostaglandin D2 and cannot tolerate aspirin so to learn that licorice might help is very interesting.

Good thing I like the taste of it.

Sounds like you prefer the tea. (and you may have answered this in a previous post but....) which forms/brands do you observe the most benefit? Is the candy even helpful?

Also, you said you get "immediate relief of all your POTS symptoms"- what does that mean? Which symptoms?

I'm glad you put up some reports of the BAD effects that this could have on SOME people too. But, how many of you read the whole thing to find out if you were one that licorice would not be such a good fit for?

Those with hypertension and low NO this would not be so good for. It does cause fluid retention and salt retention - it lowers potassium levels, it lowers renin and aldosterone levels along with angiotension II levels (some of us are already low in this). As with florinef - since licorice has similiar properties - it can affect your adrenals and cortisol levels. It affects kidney function and can raise blood pressure and cause edema. There is one report here of it causing severe headaches because of the vasoconstricting action.

Some people do need to raise blood pressure - and lower NO. (Although, there were conflicting reports about NO being lowered in all areas of the body. But, more reports showing that overall NO is lowered with licorice.) But, not everyone does. So, although this may be wonderful for some. It will NOT be wonderful for all of us.

It's interesting you mentioned potassium, Issie. I have struggled with low potassium for some reason over the past couple of years and my doctor says to stay away from licorice. Doesn't matter too much, I hate the black kind anyway lol, always have...even black jellybeans! But, it is great that it might help some people with their symptoms!

I had no idea that licorice could be beneficial for some people with POTS. <Still learning - less than 1 year since diagnosis> However, this is very interesting. First, let me admit - I have always 'liked' black licorice (the Austrailian kind with actual licorice extract). I noticed that I crave it particularly before and during mensruation. These are when my POTS symptoms are at their very worst. During this time, if there is black licorice in the house, I cannot stop eating it!! LOL. Now I will have to try the tea.... thanks for posting this topic.

Some brands of licorice candy contain molasses, making it a rich source of potassium and iron--and you might actually crave too during menstruation. And some "licorice" candy contains only anise seed flavor -- no real licorice in the candy.

I only know this b/c I have also always loved licorice--although I am partial to chocolate too :)

Are you still using licorice? My son is finally off florinif but I want to have an natural alternative to try if his blood pressures start to drop again. My son really does not like tea or licorice candy. Does this stuff come in capsules? Starting to go through some of your articles now. My son has been off his flornif for a week. So far his blood pressures are staying up. Any suggestions?

You can get deglycerized licorice in capsules. People often use it when they have heartburn. I tried it a long time ago for a weird bout of heartburn I was experiencing and it helped more than any over the counter antacid.

You may want to read more about it at this link. Pure licorice in too large amounts can lower potassium and increase blood pressure, according to what I understand. So perhaps it acts similarly to florinef?

I'll bump an older thread on licorice. The first article posted by Rama in that thread is very detailed and it's worth reading if you're looking into licorice.

Maybe if its mostly licorice and not licorice flavor. I wish I could take this stuff but I probably shouldn't since my potassium is low. :-( and my bp gets high

That's interesting. My prostaglandin levels were low; now wonder whether it was (is) the licorice rather than lab error as Afrin suspects. I take the capsule form but take it on and off because I already have chronic diarrhea and worry about it lowering my potassium. Don't need more electrolyte challenges; already have enough challenges :unsure: .

I am on day six of improved symptoms. Right now, I am giving much of the credit to licorice. Knock on wood, because I am due a crash. For the last six days my heart rate has been tempered, and my head symptoms have been tolerable.
