Fluid extract can be taken in the amount of 2 to 4 ml three times per day.

Types of interactions: Beneficial Adverse Check

Replenish Depleted Nutrients

Reduce Side Effects

  • none

Support Medicine

  • Albuterol

    A test tube study demonstrated that the bronchodilating effects of salbutamol (albuterol) were significantly increased by the addition of forskolin, the active component of the herb Coleus forskohlii. 2 The results of this preliminary research suggest that the combination of forskolin and beta-agonists such as albuterol might provide an alternative to raising the doses of the beta-agonist drugs as they lose effectiveness. Until more is known, coleus should not be combined with albuterol without the supervision of a doctor.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Ephedrine

    A test tube study demonstrated that the bronchodilating effects of salbutamol, a drug with similar actions in the lung to ephedrine, were significantly increased by the addition of forskolin, the active component of the herb Coleus forskohlii. 3 The results of this preliminary research suggest that the combination of forskolin and beta-agonists (like ephedrine) might provide an alternative to raising the doses of the beta-agonist drugs as they lose effectiveness. Until more is known, coleus should not be combined with ephedrine without the supervision of a doctor.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Epinephrine

    A test tube study demonstrated that the bronchodilating effects of salbutamol, a drug with similar actions in the lung to epinephrine, were significantly increased by the addition of forskolin, the active component of the herb Coleus forskohlii.4 The results of this preliminary research suggest that the combination of forskolin and beta-agonists might provide an alternative to raising the doses of the beta-agonist drugs as they lose effectiveness. Until more is known, coleus should not be combined with epinephrine without the supervision of a doctor.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Salmeterol

    A test tube study demonstrated that the bronchodilating effects of salbutamol, another beta-adrenergic bronchodilator drug, were significantly increased by the addition of forskolin, the active component of the herb Coleus forskohlii.5 The results of this preliminary research suggest that the combination of forskolin and beta-agonists might provide an alternative to raising the doses of the beta-agonist drugs as they lose effectiveness. Until more is known, coleus should not be combined with salmeterol without the supervision of a doctor.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.

Reduces Effectiveness

  • none

Potential Negative Interaction

  • Aspirin

    There are theoretical grounds to believe that coleus  (Coleus forskohlii) could increase the effect of anti-platelet medicines such as aspirin, possibly leading to spontaneous bleeding. However, this has never been documented to occur. Controlled human research is needed to determine whether people taking aspirin should avoid coleus.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
  • Pseudoephedrine

    A test tube study demonstrated that the bronchodilating effects of salbutamol, a drug with similar actions in the lung to ephedrine, were significantly increased by the addition of forskolin, the active component of the herb Coleus forskohlii. 6 The results of this preliminary research suggest that the combination of forskolin and beta-agonists (like ephedrine) might provide an alternative to raising the doses of the beta-agonist drugs as they lose effectiveness. Until more is known, coleus should not be combined with ephedrine without the supervision of a doctor.

    The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
