BOXWOOD Overview Information

Boxwood is a plant. People take chemicals from the leaf to make medicine (boxwood extract). The leaf itself should not be used for medicine. It can cause serious harm, including death.

Boxwood extract is used to treat HIV/AIDS and to boost immunity. Boxwood extract (SPV 30) is not usually found on store shelves. Most users get it through internet sources or AIDS buyers' clubs.

Boxwood is also used for arthritis and as a “blood-detoxifying agent.”

How does it work?

Boxwood might stop viruses from reproducing, but there isn't enough scientific evidence to support this theory.

BOXWOOD Uses & Effectiveness What is this?

Insufficient Evidence for:

  • Treating HIV/AIDS. There is early evidence that 990 mg per day of a specific boxwood leaf extract (SPV 30) might delay disease progression in HIV-infected people. It seems to delay decreases in CD4 cell counts, increases in viral load, and/or progression to AIDS in HIV-infected people who have no AIDS symptoms. A higher dose of 1980 mg per day does not seem to be effective.
  • Stimulating the immune system.
  • Arthritis.
  • Detoxifying the blood.
  • Other conditions.
More evidence is needed to rate the effectiveness of boxwood for these uses.

BOXWOOD Side Effects & Safety

Boxwood extract (SPV 30) is POSSIBLY SAFE for most people when taken by mouth for up to 16 months. It sometimes causes diarrhea or stomachcramps.

It’s LIKELY UNSAFE to use whole boxwood leaf. It has serious side effects that the leaf extract doesn't seem to have. Whole boxwood leaf can cause poisoning, including life-threatening side effects such as seizures and paralysis. It can also cause death.

Special Precautions & Warnings:

Pregnancy and breast-feeding: It’s LIKELY UNSAFE to use whole boxwood leaf, whether or not you are pregnant or breast-feeding. Not enough is known about the safety of using boxwood extract during pregnancy or breast-feeding. Stay on the safe side and avoid use until more is known.

Slow heart rate (bradycardia): Boxwood extract might slow down the heart rate. This could be a problem in people who already have a slow heart rate.

Gastrointestinal tract blockage: Boxwood extract might cause “congestion” in the intestines. This might cause problems in people who have a blockage in their intestines.

Ulcers: Boxwood extract might increase secretions in the stomach and intestines. There is concern that this could worsen ulcers.

Lung conditions: Boxwood extract might increase fluid secretions in the lung. There is concern that this could worsen lung conditions such as asthma or emphysema.

Seizures: There is concern that boxwood extract might increase the risk of seizures.

Urinary tract obstruction: Boxwood extract might increase secretions in the urinary tract. There is concern that this could worsen urinary obstruction.
