Monitor for rare occurrences of bleeding especially patients who are on anticoagulants or antiplatelets. Examples: Chuan Xiong (Rhizoma Chuanxiong), Dang Gui (Radix Angelicae Sinensis) and Dan Shen (Radix et Rhizoma Salviae Miltiorrhizae). Recognize that some herbs, such as Dang Gui (Radix Angelicae Sinensis), contain phytoestrogens. However, the use of herbs with phytoestrogen effect in patients with breast cancer is a large topic best addressed in a separate publication. Bao He Wan (Preserve Harmony Pill) should not be taken in patients with wheat or gluten sensitivity. There is no clinical trial data, but theoretical interactions exist for Shan Zha (Fructus Crataegi) with antiarrhythmics, antihypertensives, digoxin, and antihyperlipidemic agents. |

Herbal formulas should not be used in place of standard of care such as surgical resection Herbal formulas should not be used to address symptoms (hyperactivity, insomnia, auditory hallucinations) caused by steroids given for chemotherapy premedication Herbal formulas are not appropriate for severe nausea and vomiting caused by gastric outlet obstruction due to cancer Herbal formulas should not be used in place of antibiotics for infectious symptoms such as fatigue, dyspnea, and productive cough Patients with antibiotic related diarrhea such as C. difficile colitis (diarrhea, cramps, mucus in stool, nausea, fatigue, should not be treated with herbal formulas) Patients on blood thinners for pulmonary embolism or other clots, are not good candidates for herbal formulas, especially if their insomnia or dyspnea symptoms are related to physical pathology. There is also the additional risk of bleeding |

Take herbs separately by 2 hours (pharmacokinetic interactions on absorption, distribution, metabolism, elimination) CYP450 induction: some herbs may induce CYP450 and decrease therapeutic effect on other medications ○ Herbs: St. John’s Wort, Ku Shen (Radix Sophorae Flavescentis), Ge Gen (Radix Puerariae Lobatae) ○ Medications: OCP/Seizure meds/antibiotic/steroids/steroids ○ Takes about 1–2 months before effect observed CYP 450 inhibition: some herbs may inhibit CYP450 and increase therapeutic action of medications ○ Herbs: curcumin, Xin Yi Hua (Flos Magnoliae), Gan Cao (Radix et Rhizoma Glycyrrhizae), Dan Shen (Radix et Rhizoma Salviae Miltiorrhizae) ○ Medications: docetaxel, tacrolimus, antifungal, antiulcer, grapefruit ○ Takes about 2 weeks before effect observed Recommendations ○ Monitor patient carefully ○ Adjust dosage of herbs as needed ○ Select another herb without interaction Ask (Gilmour, 2011 [ Review adverse effects (Posadzki, 2013 [ |
| Tips on Checking Interactions |

PubMed - “Silybum or milk thistle and CYP” or “Losartan and CYP metabolism” filter clinical study, human (no need for in vitro or preclinical studies) Learn whether drugs and/or herbs induce or inhibit CYP450 enzymes Look at other supplements and do the same Check up to date drug interaction checker - double check risk and rating, health notes interaction (See Ask pharmacist to check drug-herb and herb-herb interactions. Note that often in vitro and pharmacokinetic data is used, providing more conservative recommendations. Half-life information can be useful for guidance on when to HT before chemo/radiation. |
