I buy everything from our local health food store. The psyllium husk Yerba Prima is $7.95 and the Benonite clay we use is by Sonne's and it sells for $19.99. I am sure you could order it online as well. I don't have the name of the probotic my husband is on, because he just finished the bottle and threw it away last night, but I will find out for you. The probotic is pricy at $20.00 for a two week supply, but it is very high in intestinal flora (50 billion) and you only have to take it once per day. Also I forgot to mention, your husband may also want to try tea tree oil topically. We have mixed tea tree oil(natural anti bacterial) in with vicks vapor rub (our natural doctor recomended the vapor rub) apply it at night before bed.
