Herbalife has been involved in many health problems. Here are some examples.
Example 1: "Severe hepatotoxicity following ingestion of Herbalife nutritional supplements contaminated with Bacillus subtilis."
Example 2: "An association between intake of Herbalife products and acute hepatitis was identified in Israel. We call for prospective evaluation of Herbalife products for possible hepatotoxicity."
Example 3: "Hepatotoxicity is probably associated with the use of Herbalife products. Hepatotoxicity due to herbal remedies is an important differential diagnosis in the diagnostic work-up of liver injury."
Herbalife is sold as a supplement and supplements are not approved by the FDA, are virtually unregulated, do not have the protections afforded foods and drugs, are not recommended by the US National Institute of Health, do not require any testing, are often contaminated, may not even be what the label says, usually contain cheap ingredients, are often over priced scams, have been known to be dangerous, and can have numerous adverse or unwanted side effects.
And, because Herbalife is only a crutch for healthy options, it should be avoided. Aloe is an over-rated fad ingredient in countless products and has little to no value to people. It's like acai, hoodia, and all the other "gray area" supplements with reputations that come from folk lore instead of science. Shakes are also a terrible way to get nutrition on a regular basis because they contribute very little to the health of your digestive system and can deliver huge calories in seconds...no mastication, salivation, etc. It sounds like your Mom is a fad freak. You should try to eat healthy...good food is all you need. If you need to know how to eat, here's how.
Whether you want to gain weight, lose weight, add muscle, or maintain, you should use the same diet. In other words, everyone should be eating essentially the same macro nutrients (carbs, fats, protein), micro nutrients (vitamins, minerals, fiber, etc.) barring special health or medical considerations because we all have essentially the same physiognomy and there is only one version of peak health. Here is how we should all eat according to the US National Institute of Health who are among the best health professionals in the world and the people doctors listens to in the US.
Eat varied, wholesome, and high quality foods such that your daily caloric intake is about equal to your daily caloric burn while keeping your macro nutrient ratios at about 55/25/20 (%calories from carbs/fats/protein) or whatever works for your goals. Go here for more about macros --> http://www.freedieting.com/tools/nutrient_calculator.htm . Only slight changes should be made in the macro nutrient ratios to accommodate the extreme demands of special activities such as extreme athletics or inactivity due to illness.
Note: Here are the details in case you're interested:
YOU MUST make your own food choices (no supplements without a doctor's recommendation) based on your location, culture, available foods, personal preferences, personal resources, food allergies, etc. However, the words "varied", "wholesome", and "high quality" are important. And, you should consume your food in 4-6 daily meals with healthy snacks between such that you're nourishing yourself every two hours when awake.
VARIED means a variety of foods including fruits, dairy, meats, vegetables, grains, nuts, etc.
WHOLESOME means as unprocessed, unrefined, nutritious as is practical.
HIGH QUALITY means using the best ingredients, the least contaminants or fillers or unnecessary chemicals, etc.
Nutrient tracking is necessary to ensure you have the optimal caloric intake and macro nutrient balance. For most people, tracking is only required for fat loss because of the difficulty in cutting intake and nutrients while maintaining digestive and appetite satisfaction. However, tracking is an excellent exercise for noobs who are just learning how to eat right for the first time. Tracking makes it necessary to read labels, look up food nutrients, record data, plan meals and recipes, etc. And, as annoying as it may be to have to track, it is easier to do today than ever before with the help of website such as My Fitness Pal ---> http://www.myfitnesspal.com .

Try to avoid buying based on advertising and commercial propaganda. Use good sources for information. You could have found the information on Herbalife and more just by going to USA.gov.
Good luck and good health!!
