Suzuna, turnip! The paper says it makes the environment in your intestines good. I bet it does.
And then there was suzushiro, daikon radish. He's a little bugger, about the size of my pinky. And believe it or not he does exactly the same thing as turnip up there. So much for being unique.
Then things got terribly difficult. I THINK these are correct. Much time was spent on Google and consulting with my son who just wanted to play his guitar and didn't care one lick about the shape of a leaf or the length of a stem.
Next we have what just might be nazuna, shepherds purse. Nazuna helps your blood, improves your blood pressure and stuff like that.
Okay, here comes hotokenoza, nipplewort. (No, I'm not making these up as I go along.) Eating this will build you a better body.
Also had a little hakobera, chickweed. Oh boy! While looking at what this grass does I found that it is mostly used as a topical skin remedy, should probably not be taken internally, and contains nitrate. Great. Now I find this out.
And finally the fuzzy leafed gogyou, cudweed. Another appetizing name. This little fella stops coughing, clears mucous and works as a diuretic.
Remember I'm not sure the pictures match the actual description. In the end it doesn't matter because you wash all the grasses, lightly boil them, chop them to bits and then stew them in a big pot of rice gruel. Add a touch of salt for taste and voila! You have nanakusa okayu.
