Watered down Aloe Vera

I could not believe this when I read it. It is from Positive Health Publications Ltd .
Has any body been "had " by these people?

Adulteration with Cheap Non-Aloe Solids Clearly, the people who sell almost pure water and pass it off as Aloe are easy to detect and, equally obviously, they are not afraid of being detected. The circumstances just have not been created yet to make life sufficiently uncomfortable for them, even though the Trades Descriptions Act gives the theoretical ability to take action. Other suppliers who dilute Aloe try to make out that they are not diluting it, by adding back some solids of a different kind, i.e. non-Aloe solids. When this is done, simple measurement of the total solids in the product is no longer capable of exposing the dilution of the Aloe. Total solids can be made to look normal, but the point is that the solids are of the wrong kind and will not possess the biomedical properties of Aloe. This calls for a slightly more sophisticated form of chemical analysis which is capable of distinguishing between Aloe solids and non-Aloe solids.
