Lymph Savior Side Effects: What the Label and Federal Pages Say

This is the line with the most federal text. NCCIH: “The raw seeds, bark, flowers, and leaves of horse chestnut are unsafe when used orally because they contain a toxic component.” Only standardised seed extract, with that component removed, is described as likely safe for short-term use, and it “has been used safely in research studies for up to 12 weeks.”

The label names a seed extract standardised to 20% aescin, which is the form NCCIH describes. The side effects NCCIH names for that extract are “dizziness, digestive upsets, headache, and itching in some people.” On pregnancy: “Little is known about whether it's safe to use horse chestnut seed extract during pregnancy or while breastfeeding.”

Twelve weeks is 84 days. A six-bottle pack is 180 days at two capsules a day. No federal page describes use that long.

Not published. Yerba mate leaf extract is line six at 100 mcg, and yerba mate contains caffeine. The label does not say how much reaches the capsule. FDA's consumer page gives the general figure: “For most adults, the FDA has cited 400 milligrams a day — that's about two to three 12-fluid-ounce cups of coffee — as an amount not generally associated with negative effects.” FDA also notes “wide variation in both how sensitive people are to the effects of caffeine and how fast they eliminate it.”

Without a figure, this capsule cannot be added to your daily total. If caffeine affects your sleep or your heart rhythm, that missing number is a reason to ask a doctor, and a reason to take the capsules in the morning rather than at night if you take them at all.

From the label: pregnant or nursing mothers, children under 18, and anyone with a known medical condition, unless a physician says otherwise. From NCCIH: anyone pregnant or breastfeeding should treat red clover as possibly unsafe, and horse chestnut as unknown. From FDA: anyone who already drinks a lot of coffee has an unlisted caffeine source here.

On medicines and surgery, the label is silent, so NCCIH's general line applies: dietary supplements “may interact with your medications or pose risks if you have certain medical problems or are going to have surgery.” If you take a blood thinner, a hormone, a heart medicine or anything daily, ask the prescriber first. Stop and call a doctor if you get a rash, dizziness, a fast heartbeat or stomach pain that does not pass.

This is a dietary supplement. It is not FDA approved, no supplement is, and it is not intended to diagnose, treat, cure or prevent any disease.

A side-effect page for a product with no side-effect list is really a page about what is missing. Two of the eleven herbs have a federal safety record worth reading, and both carry a pregnancy line. One line carries caffeine that nobody has counted. Seven lines have no record at all. That is not a reason to panic, and it is not a reason to relax either.

The sensible reader checks with a doctor if any of the label's caution applies, takes the printed dose or nothing, and treats any reaction as a reason to stop.
