Eat a varied diet and you will also supply your body with things that might be lacking.
More importantly, before taking ANY herbal supplement, even if it's primarily going to have a placebo effect, caution your family member to check with her regular doctor or pharmacist to make sure there isn't anything in it that will interfere with any prescription or other over-the-counter medications she is taking. Even common foods can interfere with some medications, so it's always worth checking even if the ingredients seem totally innocuous and ineffective. On the off-chance there is something in it that really does have therapeutic value, it's even more important to make sure it won't have interactions with other medications she's on.
Remember, these herbal supplements are not FDA approved or regulated until they either cross a line to making therapeutic claims, or are found to be harmful. So even if your relative is willing to spend a lot of money on over-priced seasonings, it's always worth checking with someone who knows her medical history before assuming it's going to just be a harmless waste of money.
