More like a mint candy than mouthwash.
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
Hard to describe this product. Does it work like your typical mouthwash? No. Does it leave your mouth feeling minty and fresh? Yes, to a certain extent. Would I consider this an alternative to mouthwash on a consistent basis? No, it's ok for traveling because it's easy to transport.
When you chew this tablet, it has the texture and feel of a traditional mint. It's chalky and breaks up easily.

Not a fan of this one
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
I am not a fan of this product. As many of the reviews noted, the flavor is very strong. I was surprised it wasn't more minty. This is a very herbal concoction. It also tastes of the other very strong herbs, especially the rosemary. According to the instructions, this product should be used once a day for 30 seconds. I prefer a product I can use twice a day for 45 seconds to a minute.
My experience is that it takes 30 seconds just to crush it up enough to swish it around and I don't have enough saliva in the morning due to overnight dry mouth. I have to add a little water. The tablets never crush completely and leave a mess in the sink that has to be carefully rinsed away. If I use them more often, my mouth dries out too much and tastes like the tablets all day long. It's not a bad taste but I expect it to go away after a half-hour (or so). They are really chalky.
The container isn't bad, but doesn't pour 1 tablet out at a time. Meh. I don't like touching a bunch of them each time. There is a desiccant packet in with the tablets to protect them. I am not sure this would stay closed during travel or be allowed on a plane in carry-on. It should travel ok otherwise because it's not a liquid, but I haven't tried it. I will probably not buy this product again, but in all honesty, I have bought far worse products and been disappointed far more by them.

Its like they knew what I prayed for🙏🏽
Flavor Name: Mint, Size: 3.5 Ounce (Pack of 1)
Okay, let me start by saying I am a huge skeptic. I need to research things to the nine's and read legit reviews before I buy anything new.
I have had cavities from a very young age and receeding gumlines all my life. At age 50, I have gone all natural, got rid of everything toxic, and got really healthy. I have been listening to Dr. HUBERMAN podcast on you tube and found one he did on oral health. He gets very detailed about how to heal your oral health. He spoke specifically about hydroxyapetite and xylitol and their benefits.
I then started searching for mouthwashes with these ingredients because i am seriously concerned my teeth are going to fall out from these receeding gums. I have been told all my life there was nothing you can do. I knew in my gut that was a lie. I knew there had to be a way to heal our mouths naturally.
Then found BOKA. I got them. I tried them. I lOVE THEM! They are perfect! They are minty fresh, easy to use, makes my mouth feel clean and if they actually do heal my mouth....then awesome sauce!
I read all the reviews. I see the after taste. But, i think its a personal choice. I like the after taste. It tastes and feels like a clean mouth.
I feel the tinglyness. Yes. But I believe from my health and science background it is the mint, aloe, probiotics and everything else stimulating the skin and blood to start the regeneration of skin and mineral. Im happy to report back again in a month or so with outcome plus before and after photos👍🏽
