Arginine causing a herx

Is there any reason why this amino acid would cause an increase in bartonella symptoms? Is this a good thing ? I thought I heard it could ease a lot of bartonella symptoms.

L-arginine
L-arginine is an important amino acid normally present in the body. Its levels can drop during many bacterial infections, including those from bartonella and mycoplasma. L-arginine is a crucial amino acid, needed for the replication and division of cells, protection of endothelial integrity, healing of wounds, healthy immune function, and proper hormone activity. It is strongly protective of bones and helps repair bacterial damage to them. It significantly decreases the amount of time needed for wounds to heal.
L-arginine is important to use during bartonella infections in that it strongly protects the endothelial cells from the kinds of damage the bacteria cause. It reduces the cytokine cascade the bacteria initiate and stops them from creating more habitat. Researchers have found that the use of L-arginine can counteract the majority of detrimental effects that occur.
Dosage
One or two 500 mg capsules up to 3x daily.
Side Effects and Contraindications
L-arginine should be avoided in cases of shingles or herpes as it can exacerbate the outbreak. L-arginine will not usually initiate an outbreak but existing viruses can use arginine to enhance their replication.
Supplement/Drug Interactions
L-arginine can affect blood sugar levels and should be used with caution if you are diabetic. It can also lower blood pressure and so should be used with caution if you are taking blood pressure medications.
