Overview Information

Chlorophyll is a green pigment found in plants. Plants use chlorophyll and light to make food. People sometimes use chlorophyll as medicine. Common sources of chlorophyll used for medicine include alfalfa, algae, and silkworm droppings.

Chlorophyll is used for bad breath, colostomy odor, acne, wound healing, and many other conditions, but there is no good scientific evidence to support these uses.

How does it work?

There isn't enough information available to know how chlorophyll might work.


Uses & Effectiveness?

Possibly Ineffective for

  • Reducing colostomy odor. Taking chlorophyll by mouth does not seem to reduce colostomy odor.

Insufficient Evidence for

  • Acne. Early research shows that applying a sheet containing chlorophyll to the face for 30 minutes along with light-emitting diode (LED) irradiation reduces acne compared to the LED irradiation alone in young adults.
  • Hay fever. Early research shows that taking chlorophyll for 8 weeks might reduce the use of medications used to treat hay fever but does not seem to improve symptoms of hay fever such as runny nose.
  • Lung cancer. Early research suggests that injecting chlorophyll into the vein (by IV) along with the drug talaporfin, followed by treatment with laser therapy, might reduce cancer lesions in people with early-stage lung cancer. However, this effect appears to only last for 2 weeks.
  • Swelling (inflammation) of the pancreas (pancreatitis). Early research shows that injecting chlorophyll into the vein (by IV) might reduce pain and other symptoms in people with chronic relapsing pancreatitis.
  • Skin cancer. Early research shows that injecting chlorophyll into the vein (by IV) or applying it to the skin along with laser or light therapy reduces the recurrence of cancer in people with a common type of skin cancer called basal cell carcinoma.
  • Bad breath.
  • Constipation.
  • Wound healing.
  • Other conditions.
More evidence is needed to rate the effectiveness of chlorophyll for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Chlorophyll is LIKELY SAFE for most people when taken in the amounts found in foods. There isn't enough reliable information to know if it is safe in the larger amounts used as medicine.

When applied to the skin: Chlorophyll is POSSIBLY SAFE when applied to the skin. But chlorophyll can cause skin to become extra-sensitive to the sun. Wear sunblock outside, especially if you are light-skinned.

When given by IV: Chlorophyll is POSSIBLY SAFE when injected intravenously (by IV) by a trained medical professional.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if chlorophyll is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.



Moderate Interaction

Be cautious with this combination

  • Medications that increase sensitivity to sunlight (Photosensitizing drugs) interacts with CHLOROPHYLL

    Some medications can increase sensitivity to sunlight. Chlorophyll might also increase your sensitivity to sunlight. Taking chlorophyll along with medication that increase sensitivity to sunlight could increase the chances of sunburn, blistering or rashes on areas of skin exposed to sunlight. Be sure to wear sunblock and protective clothing when spending time in the sun.

    Some drugs that cause photosensitivity include amitriptyline (Elavil), Ciprofloxacin (Cipro), norfloxacin (Noroxin), lomefloxacin (Maxaquin), ofloxacin (Floxin), levofloxacin (Levaquin), sparfloxacin (Zagam), gatifloxacin (Tequin), moxifloxacin (Avelox), trimethoprim/sulfamethoxazole (Septra), tetracycline, methoxsalen (8-methoxypsoralen, 8-MOP, Oxsoralen), and Trioxsalen (Trisoralen).



The appropriate dose of chlorophyll depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for chlorophyll. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
