Fo-ti + Lovastatin
Lovastatin brand names: Mevacor, Altocor.
Lovastatin falls into 2 drug categories that Fo-ti can interact with; the most serious is rated moderate. Theoretically, fo-ti might increase the risk of liver damage when taken with hepatotoxic drugs.
Read the full interaction reportFo-ti and Lovastatin
These two interact in 2 distinct ways. Each one is explained separately below.
Why Are There 2 Interactions?
Fo-ti interacts with whole categories of medication. Lovastatin falls into 2 of those categories, so it can interact with Fo-ti in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).
HEPATOTOXIC DRUGS
1 of 2Why this applies to Lovastatin
Lovastatin falls under HEPATOTOXIC DRUGS — the group Fo-ti interacts with.
Fo-ti has been linked to liver damage in many reports.
Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
Here's the concern with pairing Fo-ti and lovastatin: both can be tough on the liver. Lovastatin, like other statins, occasionally raises liver enzymes and very rarely causes liver injury. Fo-ti has shown up in a number of case reports tied to liver damage on its own. Stack the two, and at least in theory you could add to that strain.
I want to be honest about the evidence here, it's mostly anecdotal and theoretical, not proven cause-and-effect. This isn't a reason to panic. But if you take both, watch for signs like unusual tiredness, belly pain on the upper right side, dark urine, or yellowing of the skin or eyes, and loop in your pharmacist or doctor before combining them.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES
2 of 2Lovastatin also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.
In vitro research suggests that fo-ti might inhibit CYP3A4. One in vitro study suggests that the degree of CYP3A4 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, this evidence conflicts with animal research suggesting that fo-ti does not inhibit CYP3A4. This interaction has not been reported in humans.
Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
Here's the gist: your body clears lovastatin using a liver enzyme called CYP3A4. Lab studies hint that Fo-ti, especially the raw root, might slow that same enzyme down. If that happened in a person, lovastatin could build up higher than expected, which can raise the risk of statin side effects like muscle aches, weakness, and in rare cases more serious muscle breakdown that affects the kidneys.
I want to be honest about the strength of this, though. This is theoretical, coming from test-tube work, and animal studies didn't show the same thing. It hasn't been reported in actual patients. Still, since Fo-ti has its own liver concerns, it's worth a quick chat with your pharmacist or doctor before combining the two. Don't change your lovastatin on your own.

About Fo-ti
What is Fo-ti?
- Anti-aging and longevity
- Hair graying and hair loss
- General tonic for vitality
- Constipation
- High cholesterol
Fo-ti (He Shou Wu) is a root used in traditional Chinese medicine, often promoted for healthy aging and hair. High-quality human evidence for these benefits is limited, and processed Fo-ti has been linked to reports of liver injury, so caution and professional guidance are important.
About Lovastatin
What Is Lovastatin Used For?
Brand names: Mevacor, Altocor
Lovastatin is used to lower high LDL ("bad") cholesterol and total cholesterol in people whose levels have not improved enough with diet alone. It is also used to slow the buildup of plaque in the arteries (coronary atherosclerosis) in people who already have coronary heart disease.
In adults without existing heart disease but with high cholesterol and low HDL ("good") cholesterol, lovastatin tablets are approved to reduce the risk of heart attack, unstable angina, and the need for procedures to open blocked arteries. Lovastatin tablets are also approved for adolescents aged 10–17 with a specific inherited condition called heterozygous familial hypercholesterolemia (heFH), when diet changes alone haven't been enough.

Lovastatin Is Linked to Lower Levels of One Nutrient
Natural Medicines records Lovastatin as a medicine that can lower these. This is not an interaction with Fo-ti — it is a separate effect of the medicine, and it is a reason some people are advised to supplement rather than to avoid one:
